Important Information: Operating this unit with a generator or other off-grid service.
This welder should only be operated on a generator certied 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 har-
monic distortion (THD) of the Sine wave. If you are unsure of the power output type of the generator, contact the manufactur-
er of the generator for verication. Do not operate on square wave or modied square wave generators or converters/inverters
or damage or malfunction may occur. Damage caused by running this welder off of “dirty” power or modied 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 welder on “dirty” power usually leaves internal tell-tale signs and damages specic parts.
When operating on 240V, you will need a minimum of 7000 surge Watts. For 120V use, you will need a Operating the unit on
under-powered generators and/or on generators not rated with 5% or less THD can damage your unit. The generator manu-
facturer determines this 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 actual THD.
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 modied 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.
WARNING! Do not start or stop the generator with the welder 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 on the welder only after full gener-
ator R.P.M. has been achieved and the engine is sufciently warmed up. Closely monitor generator fuel level so that the en-
gine R.P.M doesn’t drop or completely shut down with the welder plugged in. For best practice: do not start or stop the gen-
erator with this welder plugged in, even if it is turned off. Unplug the welder 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 welder unless the ne current control knob is turned to maximum. Do not use this unit with such
welder/generators unless the Power/ne current control is turned to 100%. Some welder generators do have a separate alter-
nator for generating power. If this is the case, just 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 grounded, according to local code. Ground the
machine per the generator manufacturers instructions to meet code. Improperly grounded generators may damage the ma-
chine and more importantly may cause severe injury or death.
Extension Cord Use:
This unit will exceed the capability of most common extension cords. You should only operate this unit on an 8 gauge exten-
sion cord that is 50 ft or less in length for 240V use. For 120V use, use only with a 10 gauge extension cord that is 50 ft or
less in in length. Do not operate on smaller gauge extension cords. Operation on cords that are undersized or excessive in
length may damage the machine and void the warranty.
