IMPORTANT: Operating this unit with a generator or other off-grid service.
MINIMUM REQUIRED SURGE WATT RATING: 15,000W
MINIMUM REQUIRED THD: 5% or Less
This welder unit should only be operated on a generator certified by its manufacturer to produce clean power. Clean power is equivalent
to the quality of household or shop/garage type power. This means the generator must have 5% or less total harmonic distortion (THD)
of the Sine wave. If you are unsure of the power output type of the generator, contact the manufacturer of the generator for verification.
Do not operate on square wave or modified square wave generators or converters/inverters or damage or malfunction may occur. Dam-
age caused by running this unit off of "dirty" power or modified sine waves may not be readily apparent and can be cumulative in nature.
However, damage may present itself immediately. The damage caused by running this unit on "dirty" power usually leaves internal tell-tale
signs and damages specific parts.
NOTICE! Operation of this unit with generators not rated by its manufacturer as providing clean power (5% or less THD) is prohibited and
will void the warranty. Operation with modified sine wave, or square wave generators and inverters/converters/UPS that do not produce
"sine wave" output is prohibited and doing so will also void the warranty. Use only with generators/inverters/converters that produce an
equivalent type of sine wave used in shops, homes and "shore" type systems. The generator manufacturer determines the THD rating, not
Everlast. Do not assume that a name brand generator, or a "new" generator automatically provides clean power. Price paid does not
guarantee a clean power output either. There are multiple brands at various price points capable of producing clean power. Investigate
this before purchasing a generator. The manufacturer will usually state that a unit is clean power in the advertising information and will
state actual THD. If the manufacturer does not state it, contact the manufacturer directly for a statement concerning actual THD.
WARNING! Do not start or stop the generator with the unit switched on. Never use the generator in ECO mode or an auto-idle mode.
Even with a clean power rated generator, this action can damage the unit. Turn the unit on only after full generator R.P.M. has been
achieved and the engine is sufficiently warmed up. Closely monitor generator fuel level so that the engine R.P.M doesn't drop or com-
pletely shut down with the unit plugged in. For best practice: do not start or stop the generator with this unit plugged in, even if it is
turned off. Unplug the unit before shutting down the generator.
If using with a welder/generator, make sure the manufacturer has determined that the generator portion produces a clean sine wave.
Many older models do not. Some newer models use "divided" power between welding and generating and cannot supply the full power
to the unit unless the fine current control knob is turned to maximum. Do not use this unit with such welder/generators unless the Power/
fine current control is turned to 100%. Some welder generators do have a separate alternator for generating power. If this is the case, be
sure not to weld or load the machine while this unit is in use.
WARNING! Always make sure any generator or welder generator is properly wired and grounded, according to local and national code.
Ground the machine per the generator manufacturers instructions to meet code requirements. Improperly grounded generators may dam-
age the machine and more importantly may cause severe injury or death.
240V 1 Phase, 480V 3 Phase Operation
This unit is designed for 240V 50/60Hz single phase operation or 480V 50/60Hz three phase operation. This unit is shipped without a
plug and must be wired for the voltage you supply. If your single phase voltage is derived from 208V 3 phase Wye Type power (or your
local power company provides measured voltage 216V or less across each hot leg of power), then it is recommended that you install a
buck-boost type transformer to provide 240V output. It cannot be operated using all 3 phases of 208, 220 or 240V power. It must be
configured for single phase operation. If operating on 480V input, the welder must use all 3 phases of 480V power.
WARNING: Before connecting the unit to the power source make sure the correct voltage has been selected
with the rear input voltage selector switch. Failure to do so may damage the welder.
