Keep gas cylinders away from direct sparks.
EVERLAST DC 150A PowerPlasma - Symbol 8 DANGER! Welding and cutting operations pose serious inhalation hazards. Some of these hazards are immediate while others are cumulative in their effect. Do not weld in enclosed spaces or in areas without adequate ventilation. Fumes and gases released in the welding and cutting operations can be toxic. Use fans or respiration equipment to insure adequate ventilation if you are welding in a shop or garage area. Do not weld on galvanized metal under any circumstance. You may develop metal fume fever. Symptoms are similar to lulike symptoms. Seek medical advice and treatment if you are exposed to galvanized welding fumes.
If you experience any eye burning, nose or throat irritation while welding, these are signs that you need more ventilation.
If you feel these symptoms:
• Stop work immediately and relocate work area with better ventilation.
• Wash and clean your face and hands.
• Stop work completely and seek medical help if irritation persists
EVERLAST DC 150A PowerPlasma - Symbol 9 DANGER! Never use brake cleaner or any chlorinated solvent to clean or degrease metal scheduled to be welded or other related equipment in the area being welded. The heating of this cleaner and its residue will create highly toxic phosgene gas. Small amounts of this vapor are harmful and can lead to organ failure and death. If degreasing of a part is necessary, use Acetone or an approved pre-weld cleaner. Use the proper personal protective equipment (PPE) when handling any cleaners/solvents.
EVERLAST DC 150A PowerPlasma - Symbol 2 DANGER! People with pacemakers should consult a physician and pacemaker manufacturer before welding. There is a potential for damage or serious malfunction resulting in death. High Frequency energy (HF)/Electromagnetic Fields generated during welding can interfere with pacemaker signals, even permanently damaging it. Some pacemakers offer some shielding, but restrictions regarding amperage and HF starting of TIG arcs may be placed upon the individual. Warn all potential bystanders that they should exit the work area if they have a pacemaker or similar medical equipment before welding. Severe electrical shock leading to injury or death may occur while using the plasma cutter if the user becomes part of the circuit path. While the Amp output of the plasma cutter is limited, the unit may produce an OCV of 300V or greater. Consult with a Physician if a pacemaker is expected to be implanted.
EVERLAST DC 150A PowerPlasma - Symbol 10 DANGER! Never defeat or modify any safety guards or shields. Keep all safety covers and shields in place.
Never place your fingers in or near a fan shroud or insert any object into the fan(s).
EVERLAST DC 150A PowerPlasma - Symbol 11 DANGER! Do not supply more than 100 PSI to the air-pressure regulator supplied with this machine. If you do, the regulator may leak or explode, causing severe injury or death. Use a separate regulator mounted at the air-compressor to control supply air pressure. Never use an air compressor without a separate compressor mounted air regulator!
EVERLAST DC 150A PowerPlasma - Symbol 12 CAUTION! Trip Hazards exist around plasma cutters. Cords, cables, welding leads and hoses pose a trip hazard. Be aware of their location and inform others of their location. Tape and secure them so they will stay out of high traffic areas.
EVERLAST DC 150A PowerPlasma - Symbol 13 CAUTION! Welded metal can stay hot long after welding is completed. Burns may occur. Always wear gloves or use tongs/pliers when handling welded or cut metal. Remember the heat from the metal may catch other material on fire. Always have a fire-proof area ready to place welded components until they fully cool. Use soap stone or a metal marking marker to label the metal as “HOT” to serve as a reminder to all present in the area.
EVERLAST DC 150A PowerPlasma - Symbol 14 CAUTION! Welding and cutting operations generate high levels of ultraviolet (UV) radiation which can burn and damage skin and eyes. The intensity is so high that exposed skin and eyes can burn in a few minutes of exposure. Minimize direct skin and eye exposure to this intense form of radiation by using proper PPE and sun screen where appropriate.
EVERLAST DC 150A PowerPlasma - Symbol 15 CAUTION! Do not allow bystanders. Do not allow others without proper Personal Protection Equipment (PPE) suitable for welding to stand in the welding area or to observe welding and welding related activities. If protection is not readily available, use a welding screen to separate the welding area from the rest of the area. If no protection or screen is available, physically exclude them from the welding area by a wall or other solid divider. Keep all pets and young children away from the welding area.
EVERLAST DC 150A PowerPlasma - Symbol CAUTION! Electromagnetic Fields can be generated by this plasma cutter and radiate into the work place. The effect of EMF is not fully known. Exercise caution when welding by: NOT draping welding leads (guns/cables) over your shoulders or arms, NOT coiling them around your body, NOT inserting yourself directly between the cables, and by NOT contacting the unit while welding. DO keep the work clamp connected as close as possible to the area of the weld and directly to the object being welded whenever possible.
EVERLAST DC 150A PowerPlasma - Symbol 16 DANGER! Never touch connectors or fittings while this machine is turned on. Keep all safety covers in place when not in use. Never remove or replace the plasma consumables while the machine is turned On. Even though the torch is equipped with a “parts-in-place” safety disconnect, it is possible that overheating of the torch, excessive wear or damage to the consumables may cause this feature to malfunction. Make sure the brass safety cut out pins on the torch head remain in good repair and that the spring loaded function remains operational and keeps them fully extended when the torch cap is removed. The Open Cir- cuit Voltage (OCV) while in plasma mode may exceed 300V. This is enough to cause burns, injury severe electrical shock, injury and instant death.

WARNING!
Never use the electrical power outlet on the back of this machine for anything other than powering an Everlast brand water cooler. This is a special outlet designed for the special plasma cutter water cooler normally used for CNC operation. No other device or brand should be used in conjunction with this unit’s outlet. Do not attempt to modify, or change this outlet for use with anything else other than an Everlast brand water cooler designed for this unit. Severe damage, fire or injury may occur if other devices or other brand equipment is connected.

HF INTERFERENCE WARNING!
This unit utilizes High Frequency to generate and sustain the Pilot arc. This means that the unit is subject to emit emf/HF energy which may cause damage to unshielded components. When using the unit near or with electronic equipment such as computers and electronic and fluorescent lighting the use of this plasma cutter may interfere with the stable operation of the control systems. The use of this unit should always comply with local wiring codes, including operating on a separate, dedicated circuit and proper ground(s).
This unit may cause damage to unshielded CNC cut tables and control equipment unless the items are factory shielded and designed for use with high amperage plasma CNC type cutting. This unit should only be used with commercial CNC equipment that is fully shielded. Manufacturers of high amperage CNC cutting equipment(more than 125A) usually shield equipment from the possible effect of High Frequency. HF start is the normal type of plasma start for plasma units greater than 125A so the threat is generally recognized and accounted for in larger commercial CNC systems. This unit should never be used with home-owner or noncommercial CNC type tables and controls.
HF emissions can be controlled with use of proper shielding/ grounding techniques and maintenance of the HF spark gap. If problems are experienced in a commercial environment, call Everlast Tech Support for help diagnosing and reducing interference.

Duty Cycle
Duty Cycle is simply the amount of time out of a 10 minute period in which the unit can operate. For example, if this unit has a duty cycle of 60% at maximum output means that the unit can be operated for 6 minutes out of 10 minutes. This may be continuously, or intermittently during the 10 minute period of time. This rating standard (United States) is based on a maximum ambient temperature of 40 C. Operating above this point, or at lower temperatures with high humidity may reduce the duty cycle rating. Of course, the duty cycle may increase somewhat as ambient temperature drops. Regardless, this unit’s duty cycle is not controlled by a timer. Rather, this unit is equipped with a heat sensor located on a heat sink near the critical power components of the plasma cutter. If the operating temperature of the unit is exceeded, welding output will stop and an over-temperature warning light/error code will be displayed on the panel. If a duty cycle event is registered, do not turn the unit off! Allow the plasma cutter to continue to run at idle for at least 10-15 minutes until the temperature has fallen enough to reset the sensor and over-temperature warning light. Even if the unit resets, allow the unit to cool for a full 15 minutes, or the duty cycle will be more quickly triggered since the unit resets just below the heat threshold. The fan (s) must continue to run for a full 15 minutes to cool the unit properly after the duty cycle shut down has occurred. After 15 minutes of cooling, you may switch the unit off if you are finished welding. If the unit does not automatically reset after 15 minutes, turn the unit off. Wait for 15 seconds be- fore turning the machine back on. If the unit does not reset, contact technical support for further advice and assistance. As a best practice, when you have completed welding and have been welding continuously for extended periods of time, keep your unit on for 10 additional minutes without welding to allow it to cool.

The intentional and/or repeated triggering of the duty cycle protection feature on this unit will shorten the lifespan of the unit’s electronics and can weaken internal components. The effect of overheating your unit repeatedly takes a cumulative toll on the unit.
NOTICE: These units are tested by an international and independent certifying agency for their ability to sustain the claims of duty cycle, under lab induced conditions which are typically more stringent than average shop conditions.

DUTY CYCLE AND CNC USE

When considering this unit for use with CNC applications, keep in mind that CNC applications may require nearly a 100% duty cycle. For this reason, the unit should be used at or near the 100% Duty Cycle Amperage rating of the unit, and not at the full maximum amperage. See the specification chart for this rating. This does not mean the unit cannot be used at the maximum Amp rating of the unit (the 60% Duty cycle rating), but it does mean that special attention should be taken when cutting parts that may require over ten minutes of cut time to complete, or when rapidly cutting one part after the other at maximum settings, without sufficient cooling time between parts being cut.

Keep in mind that the 100% duty cycle Amp rating does not mean that this unit will cut continuously for an infinite period of time. The duty cycle is based on a clearly defined 10 minute window of time. For example, a 100% duty cycle does not mean the unit will cut continuously for 25 minutes without a rest for cooling. It only means it will cut up to 10 minutes at the rated amperage without having to rest a cool. This means that after the 10 minute time period has expired, the unit may overheat if the unit continues to cut without a rest. But in practical terms, though, when using at much lower amperage than the 100% rating, continuous or near continuous cutting may be possible in some circumstances. Additionally, ambient operating conditions and other factors such as cleanliness of the internal parts can affect the duty cycle positively or negatively. This unit regulates duty cycle by means of a thermo-sensor rather than a timer, so duty cycle may vary disproportionately at times, and is not a completely linear function.

Breaker Sizing and Wiring Requirements
Before installation of this unit in any facility, always consult a licensed local electrician familiar with the requirements of properly wiring a plasma cutter into the electrical supply. Refer to the National Electric Code (NEC) and local codes. If needed, refer the electrician to Article 630 of the NEC during consultation to determine proper application and wiring needs. Use the I1MAX and the I1EFF ratings listed above to determine the proper breaker and conductor (wire) sizing required. Everlast plasma cutters are designed around use in industrial wiring applications and are intended to be used with modern electrical systems. Household wiring may need to be upgraded before this plasma cutter may be installed. Additional HF protection and isolation may be needed if this plasma cutter interferes with the operation of electrical/electronic equipment.
IMPORTANT: Do not modify plasma cutter wiring. This unit meets the standards for conductor sizing on the power cable and takes into account power cable length, duty cycle and rated current.

NOTICE: If any electrical disturbance is noticed as a result of the high frequency interference that is possible with the operation of the inverter switching and operation, the HF service bolt should be connected directly to a 12 gauge wire that is bonded directly to an outside copper ground rod driven into moist soil. Additionally, all metal items including any metal frame or sheeting of the building should be connected and grounded to separate copper ground rods driven into the ground at 10 foot intervals around the perimeter of the building. This includes items such as tables, carts, rack material, metal surrounds, etc. that may act as “antenna” to radiate/absorb HF energy. Additionally, all cords and welding leads should be twisted together and run directly to the work without coils or excess cabling. Normally, this will not be required, but it is supplied in the case of any interference that may be observed. This is usually observed in older or non standard installations where grounding and ground isolation is a problem.

WARNING!
Never connect the torch or work clamp to the machine while the machine is switched on. Never torch any fitting or torch connector while the unit is switched on. Touching the connectors while running may result in severe shock, burns or electrocution. Always switch the machine off before changing consumables or touching any of the cutting parts (consumables) of the torch.

Setup Guide

Getting Started
UNPACK YOUR UNIT.
Upon arrival, you will need to completely unpack your unit, and check things over. This is a time sensitive matter. Do not delay or hold the plasma cutter unopened in the box. First, make sure the unit is opened from the top. Be careful with using knives and sharp objects so you won’t cut cords and cables inside the boxes. Lay all items out and inspect them.

You should have the following in your box:

  1. Plasma cutter with built in water line connections for optional water cooler use.
  2. Air-Regulator with built in water trap/particulate filter.
  3. 200A Work Clamp (approx. 9.5 ft with cable).
  4. Consumable Starter Kit for Plasma.
  5. Torch, Air-Cooled Innotec LT150, Optional Water-Cooled machine torch.

When you receive your package, inspect the unit for damage. Check for the presence and general condition of the accessories. Some slight rubbing or chaffing of some of the accessories may be present, but this is considered normal. Most notably, the torch may appear to be used or fired. This is because it has been live tested in the factory for proper operation before putting into the box. If any item is damaged or missing, please inform Everlast within 72 hours of product receipt. See pages 4 and 5 for more details. Assemble the handle with the supplied screws. Do not overtighten the screws.

EVERLAST DC 150A PowerPlasma - PowerPlasma

NOTICE: The unit comes with a basic consumable starter kit, designed to get you only through a couple days of plasma cutting. You should have 5 standard 150A cutting tips and electrodes. You will need to pur- chase a more extensive kit soon after receiving and using your unit. If you don’t order extra consumables soon after you receive this unit, you may run out more quickly than you expect. This kit contains stand-off type, non-shielded consumables that are sized for the maximum Amp operation of the unit are designed for stand-off cutting. Lower Amp operation, gouging or drag cutting will require the purchase of additional consumables (See torch parts page for amp ratings and sizes). Additionally, some miscellaneous parts may be found together with the consumable kit which may include fasteners, and some items for the air regulator required for assembly. If you think you are missing a needed part, check the consumable kit bag before calling Everlast for replacement.

POWER UP AND TEST YOUR UNIT.
You will need to fully test the unit as soon as possible. Within 72 hours after receipt of the unit, be sure to have every thing you need at hand to test the unit. Make sure the correct input power, wiring, and plug configuration is being used. Then, power up your machine without any accessories installed. Allow the unit to idle for 15 minutes. Check and observe operation of knobs, controls and buttons, cycling through each as required. Make sure the fan is running at full speed. After the test is completed, turn the unit off, connect the accessories, shielding gas (customer supplied) and conduct live testing of all the functions and features of the machine. For testing and cutting make sure work clamp is connected di- rectly to the part being welded (work). Check for arc starting and stability. If problems are observed, contact Everlast. See page 5 for more information. NOTICE: Cosmetic damage claims after 30 days will not be accepted, unless Everlast is contacted and informed of such delay and reason for such a required delay (i.e. Overseas in deployment).

CHECK FOR LEAKS.
Be sure to check for gas and water leaks before attempting to cut. Connect all the air and water lines and tighten and recheck any related clamps, plugs and fittings. If you hear or suspect air leaks, use warm, soapy water (or a dedicated leak testing solution available from welding suppliers) and spray on all rear external connections. If any leaks are present, bubbles will form around the area of the leak. Tighten any clamps or fittings found to be leaking on the air and water tubing connecting the unit and torch to the air compressor and optional water cooler . If the regulator is leaking, make sure the pressure is not more than 90 psi, and tighten the small screws on the regulator with a screw driver. If too much air pressure is applied, the regulator may have blown internal and external O-rings. Check and remedy if the regulator persists leaking. If the problem cannot be remedied, or internal leak is suspected contact Everlast.
NOTICE: A small drop in set pressure and operating pressure (while cutting) is normal. This does not indicate a leak. This drop should never be more than 4 to 5 psi and is usually less than 3 psi. Setting the unit one LED light over the target pressure will offset this drop and allow the unit to perform satisfactorily while cutting. If the pressure drops more than 3 to 5 psi, this usually indicates the supply hose is too long or too small for the length it is running before reaching the unit. Always keep the supply hose as short as possible. Use 1/2” air hose or larger for best results.

DISTANCE YOUR PLASMA CUTTER FROM YOUR WORK.
As a best practice technique, be sure to locate your plasma cutter away from the immediate area you are welding. Sparks and debris thrown by the plasma cutting process can enter the unit and cause damage. Do not intentionally cut with the plasma cutter on the work station or in the immediate area of the cut. This includes any grinding or milling operations that may occur in the area. With CNC operation, keep the cutter out of the immediate area of the cut table. Keep in mind the fan draws air in from the rear and exhausts out the front and the sides of the unit.

GIVE YOUR PLASMA CUTTER SPACE TO COOL.
The plasma cutter needs room to cool itself. Place the unit in a place that will allow 18” from all sides to allow for proper cooling. The plasma cutter pulls air in from the rear, and pushes it through the unit’s heat sinks to cool the electronics. The air is then exhausted through the front panel and side louvers of the unit. If any of sides is blocked or restricted, the duty cycle will be reduced, and overheating will occur, leading to possible damage if the restriction is severe enough. Never attempt to restrict air flow by attaching filters to the vents or by modifying your fans for “on demand” service.

CONNECT YOUR UNIT TO THE OUTLET.
This unit is designed for 480V 3 phase use only. Do not attempt to connect this unit to any other power source.
This unit is designed for commercial use and is not intended for homeowner or small shop use where single phase power may be present. In addition, all three phases must be used. This cannot be used with single phase 480V, two conductor configuration.

NOTICE:
There are special rules centered around wiring an outlet for service with a welding machine. The National Electric Code under Article 630 has developed specific regulations for wiring electrical service for welding equipment. These are different than for other types of service such as a stove or dryer in a household or even in a commercial application. You need to consult and/or employ a locally licensed industrial electrician familiar with industrial wiring codes and techniques before installing this unit to make sure all national and local codes and regulations are followed. If you are not qualified to make these connections, don’t. Everlast is in no way liable for any damages caused by improper connection of your plasma cutter. Your plasma cutter should be on a dedicated branch circuit not far from an electrical disconnect box. Importantly, it should not share circuits with other shop or household items. If possible the unit should be wired direct into a disconnect. If this is not possible then use a suitable 480V 3 phase rated plug capable of supporting the rated amperage of this machine that is connected direct to a disconnect device that is on a dedicated branch.
In addition, OSHA rules governing line de-energizing may apply to installation and maintenance of this machine.
Lockout or disconnect power to the disconnect box before connecting the input conductors. Connect the green ground wire first before connecting any other wire. This unit does use a breaker type switch that turns the unit on and off and which provides a disconnect at the ma- chine, but cannot easily be locked out to prevent use, and does not prevent flow of power to the plasma cutter itself.

Wire Configuration 3 Phase 480VEVERLAST DC 150A PowerPlasma - Wire

ADVISORY:
This unit uses an High Frequency (HF) mechanism to create a pilot arc without touching the steel. This can cause interference with unshielded electronics in proximity to the plasma cutter. It may also interfere with operation of lower tiered CNC plasma tables that are unshielded.
Even with shielding some disturbances may be noticed. If this is the case, consider grounding all metal objects in the affected area of at least fifty feet at regular distances prescribed by your electrician. This includes tables, pipes, racks, plumbing, conduits and power boxes. If being used in a metal building, every panel should be connected via a braided copper wire.
Use a braided 12 gauge wire to connect all objects, providing a direct ground to earth via a copper ground rod driven in the ground to the outside the building. Space every fifty feet. Ground rods must be driven in moist earth to be effective.
It may also be necessary to create a “Faraday” cage made of copper or brass screen over windows and open doors to prevent High Frequency leakage to nearby areas.
The plasma cutter also provides a ground bolt in the rear to provide an easy way to ground the case as well. This must be grounded when grounding other metal items in the vicinity.
Regardless of perceived interference, always keep the plasma cutter away from communication cables and commercial powerlines. Separate them from the plasma cutter by at least 50 feet. This includes power heads.
This work should only be completed by a qualified electrician familiar with industrial applications and the rules and agencies governing them.

CONNECT THE AIR COMPRESSOR
What do I need to be able to plasma cut?

The unit comes with everything you need as far as a basic starter kit for consumables, torch and regulator. However, you will need to supply a few things on your own.

  1. You will need a suitable air-compressor and at least 1/2” supply line hose. 5/8” supply may be required for long distances. The input side on the regulator is the standard industrial 1/4” quick connect fitting. Suitable units should follow recommendations found in the product specification recommendations. Compressors supplying less than 9 CFM @ 90 psi with less than a 60 gallon reserve capacity are not suitable for this unit.
  2. You will need to be able to regulate your air at the air compressor. Do not use the pressure switch on the air compressor to control the air pressure. A gate or ball valve installed on the air compressor is not enough either. You will need an adjustable regulator which will control the air pressure at the tank. The regulator that you install on the unit is to be used to regulate actual cutting pressure. You need to be able to regulate the supply pressure down to 90PSI at the air-compressor. If you supply more than 100PSI to the cutter’s regulator, you may damage the regulator.
  3. You will need a separate air-dryer. Moisture is the enemy of any plasma system and will destroy consumable life and eventually torch as well. The regulator/filter included with the unit is not sufficient to remove moisture from the system. It is designed to trap particulates and slugs of water created by the coupling/ decoupling process. A refrigerated system is not necessary. We recommend you look at the cartridge type systems that have replaceable elements for a budget alternative. If these are not available, consider at least having a replaceable paint gun dryer mounted inline and monitor the moisture it traps and replace it often.
  4. You will need additional consumables with different sizes to match the cut Amperage. The stock consumables are designed for use at the maximum amperage of the machine. The orifice in the plasma tip is specifically designed for a narrow range of Amps. To see that range, check the plasma torch pages of this manual, and each tip diameter corresponds to a specified amp range. Lowering air pressure to try to compensate for lower Amps results in poor quality cuts and inconsistent arc behavior. Always match the consumable size to the Amperage being used.
    NOTICE: For direct on-the-metal drag cutting and CNC use, special shielded consumables.

Connect Regulator To Cylinder And Unit.
NITICE:
Depending upon model, regulator may be mounted either on the rear or the side of the unit.EVERLAST DC 150A PowerPlasma - Connect Regulator To Cylinder And Unit

Install the air pressure gauge in the middle hole of the regulator.
The regulator/water trap is connected to the rear of the cutter via the screw holes on the case.

IMPORTANT:
Do not reverse air flow direction on the regulator! Make sure the arrow stamped on top of the regulator coincides with the direction of air flow. If flow direction is reversed, it can cause operational issues.

The PowerPlasma 150H uses a multi-point connection. These connections also include water cooled connections for the optional water cooler and water cooled torch. But whether the torch is air cooled or water cooled, the connection of the torch is essentially the same. With the water cooler, the water cooler water supply line connects in the rear and the torch water cooled lines connect in the front.
The standard unit is equipped with an Innotec HF LF150 series torch.

How Do I Connect The Torch? EVERLAST DC 150A PowerPlasma - Connect The Torch

  1. Work Clamp Connection
  2. Pilot Arc Wire Connection
  3. Torch Switch/Control (Not used for CNC applications)
  4. Cool Water to Torch (For optional Water-Cooled torch only)
  5. Main Power and Air Line (Air and Water Cooled torches)

The torch supports a wide range of amperages when the correct size and type of consumables are used.

When operating with CNC plasma tables, Everlast discourages the use of hand held torches, and recommends that the user purchase the optional machine torch. While Everlast does not outright prohibit their use with CNC systems, it should be noted that hand torches are more prone to wearing out prematurely and failure. While the consumables are the same between the hand torch and the machine torch, there are slight differences internally that make the machine torch more suitable for longer life. Machine torches have straight sides which can be easily measured and squared. The hand torch has a slight angle and bevel to the torch head, which makes getting it truly perpendicular to the torch piece much more difficult. Even prefabricated adapters and hand torch holders are notorious for slipping or holding the torch at a angle other than a true 90 . While squaring the machine torch, make sure that the plate is not warped by checking the torch on opposite sides first with a speed square or machinist’s square. If one side reads square and the other side does not, then it is likely you have a warped plate, or loose holder. After checking the initial two opposing sides, rotate 90 clockwise around the torch circumference and check the torch for squareness in that direction. Then check the opposing side. Once square, check all sides again for squareness. If the torch needs a major adjustment in one direction, you will need to check the other direction for squareness, since adjustment with some torch holders allows movement in all directions.
Out of square torches cause a lot of issues with beveled cuts. If you notice a cut that is beveled in one direction of travel, you should suspect a warped plate, cutting deck or an out of square torch. Slight bevels caused while cutting around circles are normal, but a change in direction of travel can change the amount of bevel and the direction of the bevel.

Squaring the Machine Torch EVERLAST DC 150A PowerPlasma - Squaring the MachineSquare the torch on all four sides to ensure the torch and the plate are level. Check at every 90 °, all the way around the torch. Recheck all sides after any adjustment has been made.

3 Pilot Arc Thumbscrew The torch pilot arc is connected here. This provides the autolighting and relighting of the torch. If this is not connected the torch cannot function properly.
4 Torch Water Line Connector
(Raise Cover to Access)
Connect the water line of the optional water cooled torch to this connector. When the water cooling mode is selected, this line must run through the plasma cutter instead of directly from the cooler. If no water flows through this line, the Plasma Cutter will sense a no-flow situation and will not cut.  If this happens, an E04 code will be displayed simultaneously as confirmation. The return line is connected directly to the water cooler from the torch however. Be sure not to mix up the air and water lines or damage to the torch will
result. Make sure your lines are connected correctly before use and that the water is connected at the rear.
5 Main Torch Connector
(Raise Cover to Access)
The unit may be operated with a water cooled or an air cooled torch. This is the main torch connector where air and power is supplied to the torch. Do not mix up the main torch connection and the water cooler connection or damage will result to the torch.
6 Torch Switch Control Connector The torch switch of the Plasma cutter connects to this fitting for hand cutting.  CNC cutting and arc activation is controlled  through the rear socket.

WARNING!
Never connect the torch or work clamp to the machine while the machine is switched on. Never touch any fitting or torch connector while the unit is switched on. Touching the connectors while the machine is switched on may result in severe shock, burns or electrocution.

1 ON/Power LED N/A The ON LED should be lit while the unit is in operation. This confirms that the switch is powered on.
2 Display Area/Warning LED’s Multiple The Display registers the information of the parameter that has been selected and displays either in Amps (A) or Seconds (S) The
warning LED’s will illuminate when a critical condition has occurred. When one or more of these lights are triggered to illuminate,
cutting output will cease to protect from damage.  From Left to Right Order:
• The Over-Current light registers an internal or external electrical fault. If this light has been triggered, check voltage input and
phase related issues and reset the machine. If the light does not clear after resetting the machine by cycling the power switch, it’s
likely internal damage has occured. Contact Everlast Technical Support to for further diagnosis. Do not attempt more resets or
further machine damage may occur.
• The Over-Temperature light registers when the duty cycle has been exceeded.  Allow the unit to cool for 15 minutes while the
unit remains switched on. Check for obstructions and cleanliness of the unit. Reset the machine by cycling the power switch after
15 minutes if the light does not clear automatically.  If the Over-Temperature light does not clear after reset, contact Everlast
Technical Support for further diagnosis.
• The Low/High Air pressure warning will illuminate if air pressure is critically low or high.  If the pressure drops below approxi-
mately 45 psi, the light will illuminate to protect the torch from damage.  This critical high/low protection does not mean that air
pressure is set to an ideal level if the light is off.  Set to 65 to 72 PSI for most cutting applications.
• The H20 Flow sensor senses when water flow is interrupted. This sensor is located on the machine and not the water-cooler to
ensure that when selected, the water-cooled torches are always supplied with water flow.  If the unit is set to “air-cooled” use, this
sensor is inoperative.  If the air-cooled torch is connected, be sure that “water-cooled” function has not been selected if output
problems arise.  Never attempt to bypass this sensor while operating with a water-cooled torch by connecting directly to the
water-cooler.

5 Graph-line Parameters of Plasma
Cutter Functions
Various This  graphline includes all adjustable functions of the welder.  These assist in both hand cutting and CNC cutting by offering a programmable control of the Plasma Cutter as it operates throughout the cut cycle. From Left to Right order:
• Air Pre-Flow sets a preflow time of air before the arc starts. Set to 0.0 to 0.5 seconds for best results.
• Pilot Arc Amperage allows you to adjust the pilot arc (non-cutting) amperage of the plasma cutter for maximum arc stability for different model torches. This is the initial arc that starts when the unit is triggered and that can be maintained without cutting taking place. Use as low as possible Amperage to ensure that the Pilot Arc operates smoothly to reduce consumable wear. Pilot arc usage increases consumable wear.  The Pilot arc will discontinue once the torch is brought near enough to the part being cut to establish electrical continuity to transfer the arc. Pilot Arc Amperage is best set to 20-25A for most purposes.
• Up Slope controls the time the unit increases the Pilot Arc Amperage to the “Pierce” amperage after cutting has started. This helps to minimize damage to the torch and consumables by harshly “blasting” to the Pierce amperage immediately after continuity is gained. This softens the blow on the consumables as arc transfer occurs.
• Pierce Amps are typically set higher, especially for  CNC use  while the cutting arc bores through the metal to reach the bottom of the cut and blow out the dross. This improves the delay time required, especially when cutting thicker plate while using the CNC process where torch manipulation will not help ease the blow back on the torch and the time the torch consumables are exposed to the piercethrough process.
Setting from 30 to 70% higher than cut Amperage is typically recommended. Less Amperage is available for thicker materials
as more cutting Amperage is required to cut.
The machine will not exceed the maximum rated cut amperage while using this function. For hand cutting this setting is not as
important since the torch can be manipulated into position as the arc pierces through.
If a pierce Amperage is not wanted, set pierce cutting equal to the cut Amps.
• Pierce Duration controls the amount of time that the pierce cycle stays engaged. This timed amount of delay varies by the thickness of the metal and Piercing Amperage used. If the CNC control program offers a “delay” setting, this should not be set longer than the delay programmed on the controller, unless the metal being cut is sold or varies in initial cut thickness. If a pierce duration is not desired for hand cutting, set to 0.0 S.
• The Cut Amperage should be matched to the consumable size being used and the metal thickness being cut. See formula later in this manual for determining approximate cutting Amperage needed for various thicknesses of metal.
• Downslope helps to taper off the cut and lowers the Amperage gradually until the arc terminates below the sustainable threshold.
• Post-Flow allows the air to flow from the torch after the torch arc has terminated. This is important to cooling the torch and consumables. The amount of post-flow time varies by the duration of the cut and the Amperage used. Monitor the torch consumables for discoloration. If the consumables begin to change color, increase post-flow time until the color remains stable. It does no harm to set post-flow time higher than what is required. Set Post-flow for 10 seconds for every 25 Amps set to begin with and monitor consumables for color change until the consumables are no longer discoloring.
6 Adjustment Knob N/A This knob is used to increase or decrease the value of the parameters.
7 Air Test Button On/Off The Air Test button is used to set air pressure without having to trigger the torch.  Air pressure should be set to the specified pressure while actively flowing.
8 Trigger Lock On/Off The trigger lock is designed for manual cutting of long, uninterrupted cuts. To use the trigger lock function, select the trigger lock 4T setting. Press and hold the torch trigger to start the arc. Then, release the trigger to cycle the rest of the programming until the cut is completed. Pull and hold the trigger to finish the cut and downslope. Release the trigger to terminate the arc and begin the postflow cycle. The most common mode of operation is the 2T setting. To operate the 2T function, press and hold to cycle the unit’s programming.
9 Torch Cooling Type Water/Air This selects the type of torch that is connected to the unit and activates the water flow sensor in the machine to protect the water–cooled torch. Do not by-pass the water-cooled function and connect the  red “out” coupling of the cooler directly to the torch.

Plasma Cutter Function Important Information and Warnings:
DANGER! Never touch any of the bare portions of the torch power connectors, consumables or torch control connetor while the unit is switched on and torch is connected. Severe injury or death may occur if the torch trigger is accidentally activated or becomes damaged.

WARNING! Do not use sun glasses or non cutting glasses to protect the eyes. Use at least a shade 9 for plasma cutting where the arc is clearly visible. Never use less than a shade 5, and only use that for situations where the arc is not visible. Do not use cutting shades rated only for Infrared use, such as those designed for Oxy-Fuel use. These usually do not offer sufficient UV protection unless stated otherwise.
CAUTION! Keep the torch switch isolated and the consumables in place on the torch while the unit is switched on. Turn the unit off to change consumables. Do not remove the trigger safety guard or attempt to defeat its operation in any manner. If the trigger safety becomes damaged, replace immediately. Turn the machine off to replace the consumables.
CAUTION! For most cutting applications, use the “Lock-Off, 2T” Setting. Do not use “Lock-On, 4T” unless you are familiar with its operation. Attempting to use this setting without being thoroughly familiar with this setting may cause a panic stop and can result in severe burns and injury. “Lock-On, 4T” is for only experienced users that intend to make long cuts. If you use “Lock-On, 4T”, remember that the arc will stay on until the trigger is pulled and release again. Lock-Off, 2T is the simplest operation with a “press and hold” operation. “Lock-On” requires a “pull and release” to start the arc. The arc will continue without the trigger being held. The cut will continue until the trigger is pulled and released once again.
WARNING! Do not submerge the work clamp in water, particularly for use on CNC plasma tables. Always connect the clamp directly when possible, but the clamp should never be submerged in water, or the water may siphon down the cable through capillary action and run into the DINSE connector or the machine. If the work clamp cannot be safely attached to the work without submerging it, either lower the water level of the table, or use a thick copper jumper wire direct to the work clamp which is attached directly to the work clamp.
WARNING! A poor work clamp connection may cause faulty cutting, loss of cutting power, or excessive pilot arc engagement. The Pilot arc is not designed for continuous run and the length of its time on should be limited as much as possible. poor cutting is experienced, with minimal penetration into the cut, the pilot arc may be staying engaged. Check the work clamp and cable for proper connection. When necessary, change the work clamp if the copper cable and strap have burned or looks corroded. Delayed arc transfer or intermittent arc transfer is usually a result of a poor connection.

STOP!
If the pilot arc does not appear to transfer, particularly when being used on CNC cut tables stop immediately, and investigate the cause. Usually this is a result of a poor work clamp connection, or too high of a cut height. Do not allow the pilot arc to remain on continuously. To do so will increase consumable wear greatly and/or overheat the pilot arc circuit.

Explanation of Functions and Plasma Cutting Terms

What Air Pressure do I use to cut?
The unit should maintain between 65 and 72 PSI while actively cutting. Use the air pressure target LED’s to set your pressure while the gas is flowing. Do not lower the air pressure in an attempt to improve cut at lower Amps with oversize consumables. Consumable size should always be matched to the Amp range being used to cut. Lower Amps call for smaller diameter orifices in the consumables. See the torch page and the parts information to match consumable size to the Amp range of the consumable. Using too little air pressure will rapidly accelerate wear on all torch parts and consumables. Using too high of amperage for the con- sumable will rapidly wear the consumable. For best results, buy a complete range of sizes of consumables to be able to tailor your cut needs.
Bevel. When plasma cutting a certain amount of bevel will be present. The cut will rarely be a true 90 degree cut. Usually 1 to 7 degrees of bevel may be present on the “keep” side. Ideally this figure is under 5 degrees of bevel. One side of the cut will have more bevel than the other. Measure the “keep” side of the bevel. Practice cut with your torch first before attempting precision requiring cuts to familiarize yourself with which side of the cut the bevel is being formed on. With the iPT60 torch the inside swirl ring can be flipped over to change the bevel side. If circle cutting, be sure you have identified the direction of bevel. Changing “clock” rotation of the torch in a circle cut will change the side of the bevel. See the instructions on circle cutting in this manual.
Dross. Dross is the left-over oxidized metal created by the Plasma cut- ting arc. In an ideal cut, little or no dross will be left, as it is cleanly dispersed out the bottom of the cut. Generally, though some slight dross will be present. Dross is sometimes referred to as “slag” by people who are mostly accustomed to stick welding or cutting with oxy-fuel processes. The amount of and type of dross created is affected by torch cut height, cut speed, air pressure, consumable size and even torch angle. Two types of dross are generally present: Hard and Soft. See the instructions later in the manual to identify the type and cause of different types of dross.
Edge Start Cut. When the plasma torch reaches the upper limit of the cut capacity, piercing starts are no longer viable. Usually this is anywhere from 1/2 to 2/3 of the torch rated capacity. Cutting can still be performed, but starting a cut in the middle of the metal is no longer an option. If piercing starts are attempted near the maximum capacity of the machine, wear will greatly accelerate on all torch consumables and even the torch itself. In fact a poorly performed pierce start will completely destroy the consumable set in one cut if the pierce is performed at or near the maximum capacity of the cutter. An edge start allows the torch to be placed on the very edge of the plate to be cut to start the arc. The arc actually lights right on the edge of the metal, and the torch is brought into the metal and the cut begins. A lead in is usually used to create the cut.
Kerf. Kerf is the width of the cut. Kerf will vary according to the consumable orifice size used, the stand off height, and to a lesser extent, cut speed. Kerf width is important to maintaining cut accuracy. Testing kerf width first is advised before trying to perform cuts which need a high level of accuracy. Always remember to adjust for the kerf width. Smaller kerfs can be achieved by using smaller diameter cutting tips, but cut thickness will be limited.
Lead-In/Lead Out. Lead ins or Lead Outs are simply cuts that are made at the beginning or end of the cut that will not be used in the final part being cut. These are usually tangential to circles or start outside of the part shape and travel into or out of the cut. This is done to prevent “blow out” of the kerf width and discontinuities where the torch starts/stops.
Pierce Start Cut. When the plasma cutter is sized properly and is used in an average, daily cut, the unit will not be at the all-out maximum capacity of the machine. In this case, the torch will use the pilot arc to start the arc and will begin to pierce a hole through the metal to start the cut. Of course, if desired the pierce can happen anywhere on the metal. When hand cutting, the piercing limit can be increased by starting the cut at a slight angle to keep the sparks and molten metal for bouncing back onto the torch head, and damaging it. Once the pierce begins and the cut begins to develop, the torch can then be slowly stood up vertical to cut as the flame begins to exit the bottom of the cut.

Problem: I just changed my consumables now my torch won’t light/or the arc is blowing out my tip. What’s wrong?
Check the torch diagram found later in this manual against the assembled parts to make sure nothing has been left out, assembled in the wrong order or direction and that they are firmly finger tight. Check in particular the air or water cooling tube behind the consumable, and if the torch is equipped, make sure the swirl ring is installed correctly and is seated. If water cooling is selected, double check that the water cooler is switched on and that water is flowing through the torch before using. An air lock may be present at startup of the water cooler for the first time or after extended storage.

How do I edge start a plasma cut?
Edge starts are the best type of start to promote consumable and torch life. This reduces blow back of molten material and allows a smooth gradual start of the arc and maximizes cutting capacity.

  1. Line up the hole on the tip of the electrode on the edge of the cut. Hold torch perpendicular to the cut initially, about 1/16” off the metal. Slide the yellow safety lock and squeeze the trigger. Wait for arc to start.
  2.  Once the arc starts, wait for the arc to penetrate all the way through the metal.
  3. As the torch penetrates the flame all the way through the metal, tilt the torch so there is a slight lead in the flame if metal is thin. If the metal being cut is thick, keep holding torch in a nearly vertical position.
  4. Begin moving the torch in the direction of the cut. Maintain 1/16” to 1/8” standoff height.
  5.  Move the torch fast enough so the sparks and flame trail from the bottom edge at an angle of no more than 30° and no less than 10° from perpendicular to the metal. Excess angle of sparks/flame indicate too fast of travel speed or practical cut capacity has been reached. Little or no angle indicates too slow of travel speed.

How do I pierce start a plasma cut?
Piercing starts often result in rapid consumable wear and excess blow back of molten metal deposited onto torch and consumables. This should be done only as necessary on thicker material.

  1. Tilt the torch in the direction of travel or toward the side of the metal to be discarded or wasted at a 40° to 60° angle. Slide the yellow safety lock and squeeze the trig- ger. Wait for arc to start.
  2. Once the arc starts, wait for the arc to transfer from pilot arc to the cutting arc.
  3. As the flame penetrates through the metal (at a sloped angle) rotate the torch slowly to the vertical position. Tilt the torch from 0°-15° for thin metal cuts, or hold it nearly perpendicular for thicker metal cuts.
  4. Begin moving the torch in the direction of the cut. Maintain 1/16” standoff height.
  5. Move the torch fast enough so the sparks and flame trail from the bottom edge at an angle of no more than 30° and no less than 10° from perpendicular to the metal. Excess angle of sparks/flame indicate too fast of travel speed or practical cut capacity has been reached. Little or no angle indicates too slow of travel speed.

IMPORTANT:
If you use a standoff guide with the torch, it must be adjusted to provide no more than 1/8” standoff, less if possible. Long standoff heights reduce cut capacity and quality. It also promotes rapid consumable wear and can prevent the pilot arc from transferring.

How often should I check or change consumables? 

Check consumables regularly for wear and change them out before they are completely worn out. A good practice is to check consumables before turning the machine on each time you prepare to cut. It takes only a few seconds and can save yourself a lot of extra effort later. Allowing the consumables to wear until they quit working may damage torch related components, creating a more costly repair. If the cut quality suddenly deteriorates and begins to show greater than 5 degrees bevel, stop and check the consumables for wear. Inspect the cut tip orifice for the tell-tale signs of wear including deep pitting around the orifice and an egg shaped hole. The electrode should be inspected for wear as well at this time. The cap should be pulled off, along with the tip and the swirl ring. The tip should be examined for wear. A slight pit is normal in the center of the electrode. However, if the electrode tip is pitted around the center, or the center has a deep hole in it, the tip is worn. The very center of the electrode has a special insert made of hafnium. Hafnium is an expensive and durable metal that is used for electrodes. If the hafnium insert is wearing quickly, check for water or moisture getting into the system. Also, periodically, with the unit turned off, check the spring action of the electrode by removing the cup and tip and pushing your thumb or finger down on the electrode. The electrode should depress slightly and spring back quickly without a delay. If it does not, the torch head may need to be disassembled, cleaned and lightly lubricated with di-electric grease. In some cases the sealing O-rings may be broken or dirty causing sticking. Replace- ment torch head kits are available if repair is not an option. Sticking of the electrode like this causes starting issues. Most often this condition occurs because of moisture and dirt that makes it way into the system. Additionally, do not overtighten the electrode or overheat the torch (by poor cutting techniques such as excessive piercing starts on thick metal) or the electrode threads may gall in the torch head and break off during removal. Do not under tighten it either. Use the supplied wrench to tighten the electrode. Use your fingers only to tighten with this wrench. Avoid using pliers to install and remove the consumables. This usually occurs on lower quality consumables (non-OEM) with poor chrome plating, but can occur if OEM consumables are overtightened.
NOTICE: 

When lowering amps to cut thinner material, you must change to smaller orifice nozzle. Nozzles are offered in different sizes which are made for different amp levels. See the torch parts page for amp range and size of consumables. Everlast offers OEM size and configuration of consumables originally supplied with the torch for replacements and do not offer all configurations or sizes. Everlast is not the manufacturer of the available plasma torches and does not offer all possible consumable types available for the torch series. OEM suppliers of the Innotec and other approved torches (local and online) offer extended range of sizes and configurations. If drag cutting is desired, shielded drag consumables are now available from several online sources. .An orifice that is too large for the amps being used will result in arc instability and a rough cut.

What should the torch flame look like?
The torch flame angle can tell you if you are cutting at the correct speed or not. Take a look at the examples below to help you determine if you are cutting at the correct speed.

How Do I Use a Lead-in?

When cutting an object, particularly a pattern shape, where the torch must pierce or re-fire in-line at an intersection of a cut, a lead-in cut should be employed. A lead-in is a cut that is made in the disposable part (also known as a drop) of the object to “lead” into the main part of the cut so that the destructive force of the arc is not directed into the desirable side of the cut itself. Also, all plasma cutters exhibit some angularity or bevel in the cut which is greater on one side than the other. Keep this in mind (and the direction you cut) when cutting an object to size so that too much metal is not accidentally removed and the object can be finished to the proper size.

What is Kerf? 

When you make a cut, a certain amount of material is removed from the cut. This is known as the kerf. In plasma cutting, knowing the width of the kerf is important to making accurate cuts. A typical kerf width from a plasma cutter will range from .045” to .090”. The actual width of the kerf is affected by the orifice diameter in the consumable tip and by the cut height of the torch, and to some extent the thickness of the metal. Of course the best way to determine kerf width is to make a test cut and measure it. But if you are trying to achieve a narrow kerf width in thick plate metal, you will be limited by the fact that you will need a larger orifice to support the greater amperage needed to make a clean cut. Of course, you should always match the Amperage range to the orifice diameter. Lowering Amperage too low with a large consumable will result in arc instability and sputtering. A higher am- perage consumable has a wider orifice width to support the increase in the Amperage. If the consumable size isn’t increased, the higher Amperage arc will quickly “blow” its way to a wider orifice, which will lead to instability in the arc and a decrease in cut capacity since the hole is usually oblong instead of round at that point. Going with a larger diameter orifice on sheet metal means that while the cut can be performed more quickly, the kerf tolerance must be increased and figured into the cut plans. Cutting to slowly with a larger diameter consumable on thin metals will possibly yield an irregular kerf width, and “melt back”, where the metal and the dross melt back and close over the area just cut. If you have no choice but to cut thin material with a large orifice consumable, lower air pressure just enough to allow the arc to be maintained without sputtering or blowing out. Never lower below 50 psi. I deal cut pressure is between 65 and 72 psi when the consumable size is correctly matched to the amperage used.

Component Identification and Explanation
CNC Connections
Pin and board numbers correspond to each other. 11 and 12 are not used. 8 is blank.
This is the Divided Arc Voltage Jumper Location.
Closed: 16 to 1 Arc Voltage (1-10V) (If 16 to 1 is needed, remove cover and move jumper to center and remaining pin.)
Open: 50 to 1 Arc Voltage (1-3V) (Unit is shipped with jumper installed in open position. Do not discard jumper or remove.)

EVERLAST DC 150A PowerPlasma - CNC Connections

  • Pins 1 and 2 activate (turn on) the plasma cutter to start cutting.
  • Pins 9 and 10 give the “OK-To-Move” signal. These are Dry “N.O.” style contacts. It is a non-electronic switch that closes when the pilot arc transfers to the cutting arc. Sometimes referred to as “Arc OK”.
  • Pins 5 and 7 provide the raw, undivided arc voltage, which is used by some controllers to adjust the height of the torch (THC). This is the actual cutting voltage. It runs through 2 -100KΩ resistors to prevent arcing at the connector plug. Many, but not all controllers have a raw voltage option, and is dependent upon the impedance of the input. The raw arc voltage can be used when other systems look for or expect higher voltage signal from 50 to 1 arc dividers for certain brands that produce a higher arc stretch voltage.
  • Pins 4 and 6 provide the divided arc voltage. This is selectable by moving the jumper on the CNC circuit board inside the unit to create either 16 to 1 (1-10V) or 50 to 1 (1-3V) ratio to the raw arc voltage output. Divided voltage is used by many controllers for regulating torch height control (THC). The jumper is configured for 50 to 1 voltage output (1-3V) which is technically “open”, but the jumper is installed in a neutral position. The machine must be opened and the jumper repositioned for 16 to 1 arc voltage (Remove rear cover and metal cover only to access!) The jumper for 16 to 1 arc voltage will bridge between the center pin and the other open pin position. If using 50 to 1, no change is needed. Retain the jumper for testing the unit.
  • Pin 3 is what some controller manufactures refer to as “Ground” this is connected directly to the work piece lead, which is actually a positive polarity. If the controller has a pin for ground this is likely the pin to use.

Please be aware that Everlast does not offer technical support for individual manufacturers. The CNC manufacturers should provide all necessary details for proper connection and setup of their machines. Cable colors and wire configurations are the CNC manufacturers responsibility. Everlast supplies the necessary pin-out information to the rear of the machine along with a plug adapter (CNC models). After this, all the connections are the responsibility of the CNC table owner and the CNC manufacturer.

NOTICE!
The Plasma cutter currently comes configured for 50 to 1 voltage divider for the THC. This is a 1 to 3V operating range. Some CNC tables are configured for 50 to 1 voltage divider but are calibrated based on particular brand with a higher arc voltage range than Everlast and many other brands supply on the standard volt/amp curve. In this case, the voltage range may be 1-5 volts and will not work. In this case, the voltage divider on the CNC needs to be recalibrated, or you will need to use the raw arc voltage if the CNC plasma table control system is equipped to read raw arc voltage. Do not modify the plasma cutter control board in any way or the warranty may be voided. Modification of the CNC control board inside the machine may damage the machine and cause early  failure.
NOTICE!
Do not connect anything directly to the output terminals or leads. Do not connect anything from the controller to the chassis of the cutter, especially a ground lead. Do not install any kind of converter or divider inside the machine. Do not modify the CNC control board, or the warranty will be voided.
Caution icon DANGER!
Raw Arc Voltage is dangerous! Use caution if using the Raw Arc Voltage. This is the most accurate method of control, but careless handling may result in shock or injury to the user. Many systems use either a 50 to 1 (1 to 3V) or a 16 to 1 (1 to 10V) signal to control the torch height with a raw arc voltage option.

Additional Torch and CNC Information

Can I change my torch to another brand?
These units have been specifically programmed and designed for use with the HF design torches rated for 150 and 200A.. Chang ing out to other brands to “hybridize” the unit is not recommended and may result in damage to the machine. Some brands use a higher arc voltage, and this is contro lled by the torch’s internal design and tolerances. These torches may work for a while, and offer the added convenience of cheaper bulk consumables, but will eventually damage the machine by forcing it to generate a higher arc voltage than it was designed for at any given amperage. It can also theoretically affect duty cycle ratings. If you desire to use another torch with this machine, consult with Everlast before changing. There are some appropriate options.
Why is my torch pilot arc sputtering or going on and off when I pull the trigger.
Pilot arc sputtering is often caused by several factors. The first, air pressure is too low. The second is that it may be too high. However, the third reason, and likely the most common reason is that the consumable size has not been matched with the Amperage setting of the machine. The unit is shipped with consumable sizes designed to be used at or near the maximum output of the machine. When you lower the amperage, the arc is simply being blown out or d estabilized. Think of a small garden hose you may use outside your house. Then think of (if it were possible) connecting a fire hose to the same faucet and how w eak and unstable the stream would be. Water and electricity do share similar characteristics. Use the torch page for your cutter to identify the proper size and type of consumable for your application. This can also happen if used in CNC mode and the torch holder is too tight, deforming the torch head and preventing the parts from ope rating correctly. This is common on some import brands of CNC with holders that allow too much pressure to be applied.
How do I set my plasma cutter for hand cutting?

Hand cutting is easy to learn and set. The maximum Amperage setting of your unit will cut even the thinnest pieces and do it well. However, there are two issues concerning this. You may have to move extremely fast, or dross will build up or the metal may weld itself back together. And, you may have a wider kerf than is desired. In order to avoid this, and get the most out of your unit, use the following guide to set your amperage, and to get your mach ine setup correctly. Be sure to then match the consumable size to the amperage being used. Use the torch page found in this manual for your cutter and the amperage ranges for different consumables are listed.

  • Keep your standoff to less than 1/8” distance from the work piece.
  • Always use dry air. Drain compressor daily to improve effectiveness of air dryers and to prevent them from prematurely failing.
  • Make sure work clamp is attached directly to the part being cut. Make sure the work clamp is attached to freshly cleaned metal.
  • Don’t greatly lower air pressure to try to reduce kerf or cut thinner material. Always reduce nozzle orifice size to match amperage. See Torch pages for different consumable sizes.
  • Use this as a general rule of thumb for good hand cutting speed and quality:
    1. For the first 1/8” of thickness, use 20 amps.
    2. After the first 1/8” add 10 amps for every 1/8” after that.
    3. For Stainless and Aluminum, use settings that are 40% higher.

How do I set my plasma cutter CNC cutting? Can you help provide support advice my CNC table? 

You may be looking for CNC cut charts and tables for use. Currently, Everlast does not produce such information. There are numerous brands and types of systems on the market, many are here today, gone tomorrow. It’s impossible for us to test and certify every cutting system for use. Our products carry all the standard signals needed, but Amps, speed, piercing and torch cut height is not available. Even though cut speeds and heights etc. may all appear be the same in theory between brands, there are variations that exist from CNC manufacturer to CNC manufacturer. One issue can be calibration. Another is limitation of speeds that a particular machine may have. However, we do feel the best place to get information and help in setup is from other customers with our products that have personal experience with the prod- uct. So, please see our support groups on Facebook “Everlast Welders” or “Owners of Everlast Welders for community supported information. Many customers freely share their own if you wish to join and just ask. Keep in mind those are not always accurate for your applications, but these pages can be a good starting place for you to develop your own. We are here to provide support up to the rear connection of the unit. We can only offer limited support beyond that aspect since every CNC manufacturer is different. We can help you trouble shoot basic issues with the machine and determine if we feel the unit is with the machine or with the CNC plasma table and software. Please note: We cannot troubleshoot any aspect of the CNC system other than our plasma cutters. See your CNC supplier for support on their systems. CNC rated cut capability (for optimum cutting) is typically half the rating of hand cutting due to limitations of piecing, expected cut speeds, and duty cycles of the machine. CNC operation is typically high duty-cycle, so the Amperage may need to be reduced for extended cutting to match the expected duty cycle. This is one reason that CNC use limits the overall recommendations. Although technically CNC could cut at a slow enough speed to reach the maximum cut reached with hand cutting, speeds are slower than generally acceptable for production work. Piercing is also limited due to blow back onto the torch consumables during the pierce, which limits consumable and torch life. For near maximum cuts, edge starts which employ lead ins must be used for best results.

Troubleshooting

Error Codes 

TROUBLE CODE WITH WARNING LIGHT/UNIT
STOPS WELDING BUT IS TURNED ON.
 DIAGNOSIS
E01 OVER TEMPERATURE/ DUTY CYCLE EXCEEDED.  Allow unit to rest for 15 minutes while running. The unit should reset.  If it does not or condition reoccurs, check for obstacles near unit blocking cooling. Then clean unit internals paying close attention to boards and heat sinks. Make sure unit is unplugged for 10 minutes before opening up for cleaning. For CNC use, if this is regularly occurring, arc length
may be too long causing arc voltage to go beyond  ratedspecifications. Can be  caused with after-market torches
E02 OVER OR UNDER CURRENT.  Check power input cable for length/size, check input voltage.  Run- ning on poor quality power supply or dirty power from generator. Can be caused by knockoff or “will fit” torches. Possible internal issue or failed PCB.
E03 AIR PRESSURE TOO LOW OR HIGH. Make sure air is connected before switching this on, or code will appear. Adjust pressure so that the green LED light over the gauge is solidly on.
E04 NO WATER FLOW.  Used only when the water cooled torch is being used and “Water-Cooled” is selected on the panel. Signals loss of flow or possibly cooler is turned off.
E05 TORCH SWITCH IS STUCK CLOSED.  This simply means that the arc has been trying to start and for too long.  If this does not clear after releasing the switch, turn off unit immediately and check torch switch for stuck contact.   If the pilot arc is engaged without attempting to cut for more than 3 seconds this will activate.
E06 NO AIR SUPPLY DETECTED.  Make sure air is connected to the machine correctly.
