Important Information: Operating this unit with a generator or other off-grid service.
This welder/plasma cutter multi
-
process unit should only be operated on a generator certified by its manufacturer to produce clean pow-
er. 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. Damage caused by running this welder 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 welder on
“
dirty
”
power usually leaves internal tell
-
tale signs and damages specific parts.
When operating on 240V 1 phase, you will need a minimum of 7,000 surge Watts. Ideally, it is recommended for use with 8,000 watt
generators or larger. Operating the unit on under
-
powered generators and/or on generators not rated with 5% or less THD can damage
your unit.
The generator manufacturer determines this rating, not Everlast.
Do not assume that a name brand generator, or a
“
new
”
gen-
erator automatically provides clean power. Price paid does not guarantee a clean power output either. There are multiple brands at vari-
ous 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 manu-
facturer 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 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.
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 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 welder plugged in. For best practice: do not start or stop the generator 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 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, 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 machine and more importantly
may cause severe injury or death.
Single Phase 240V Operation:
This unit should be used with single phase 220/240V output. However, the unit may be used with single phase 208V if the voltage does
not drop below 205V. If using this unit on 208V, duty cycle and display accuracy may be affected. Rated and Inrush Amperage will rise
proportionately as well. If you decide to use this machine on 208V, before installing permanently, have an licensed electrician monitor
voltage fluctuations, particularly under load and during peak use times. If the voltage remains constant, and steady without dropping be-
low the 205V threshold, this unit may be used. Damage caused by using on undervoltage power sources is not covered by the warranty.
Long arcing of the plasma may also increase amp demand.
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 to produce 240V with limited amperage draw. No other device or brand should be used in conjunction with this
unit
’
s outlet. This outlet is designed to supply 240V only. Do not attempt to modify, or change this outlet for use with anything else other
than an Everlast brand water cooler designed for 240V operation. Severe damage, fire or injury may occur if other devices or other brand
equipment is connected.
