at 104°F (40°C) ambient temperature, high local-
ized heat, air flow restrictions around the welder
and humid conditions will also affect the duty
cycle of the welder. If the unit overheats or an
overcurrent condition is experienced, an error
code will be triggered and the unit will stop
welding. An over current or under current con-
dition is usually caused by dirty power condi-
tions, over/under, voltage power supply, faulty
breaker or an internal fault. If the light is green
or yellow green, this a duty cycle issue. In ei-
ther case, if the light/code does not clear and
the unit does not resume welding output, by
cycling the power switch (after the required
amount of rest, if any), contact Everlast.
Note: The duty cycle is 35% at the maximum
output of 160 amps while operating on 240V.
Maximum Amp output will be reduced to 90±A)
Amps while operating on 120V to limit current
draw. The Duty cycle is re-adjusted to 35% at
90 Amps while operating on 120V.
The unit should be stored in a dry place where
temperatures do not drop below 0°F (-17°C) for
long term storage. Do not operate below 21°F
(-6C°). Humid/wet conditions can contribute to
the eventual decay of the circuitry in the ma-
chine. For safety reasons, do not use this ma-
chine directly in the rain or with soaked clothing
or damp protective gear, even with VRD en-
gaged. The service rating for this unit is IP21S,
and is not designed for wet environment use.
Use the carry strap or handle provided to lift
the welder. Do not suspend the unit in the air
by the strap.
Make sure that the unit's cooling fan and ex-
haust vents are kept free of obstruction. Be-
fore every operation, inspect unit for unexpected
obstructions such as insect and vermin nests.
Once a month, or as needed, clean the machine
thoroughly inside and out with compressed air.
To do this, remove the rear plastic cover first
(check for screws on the bottom). Then remove
the screws on the metal cover. Pull the cover off
by slightly spreading/flexing the bottom "flaps"
of the metal cover with your fingers. Pull up
and to the rear to remove the cover. Do not
attempt to remove the front cover or front panel
of the machine. The front panel is part of the
structure of the unit and requires significant ef-
fort and time to remove. Removing the cover to
clean the welder will not void the warranty.
However, neglecting periodic cleaning of the
welder may cause damage to the machine 's
circuit board from metallic dust or particles
General Setup and Operation
settling on the traces over time. The boards
are coated with protective conformal coatings
to protect against these issues, but even with
the protective coating, dust and metal particles
can still affect the unit if they continue to build
up. This type of neglect may be grounds to
deny warranty service as it is considered the
part of routine maintenance.
removing the covers, unplug the welder for 30
minutes allowing the internal capacitors to dis-
charge to prevent shock, injury or death. Nev-
er remove and circuit boards unless authorized.
But, while you are inside the unit for mainte-
nance, always check all plugs and connections
for tightness before replacing the covers. Do
not pinch any wires when reinstalling the covers.
Wear safety glasses to prevent eye injury from
flying particles that may get dislodged while
cleaning with compressed air. Do not concen-
trate compressed air on the skin or injury may
occur. Using "canned-air" is acceptable as well,
but do not allow components to freeze. Keep
moving the nozzle back and forth to keep com-
ponents from freezing up.
