Duty Cycle And Overheating
Duty Cycle is percentage of 10 minutes that unit can
weld at rated load without overheating.
If unit overheats, output stops, a Help message is dis-
played and cooling fan runs. Wait fifteen minutes for unit
to cool. Reduce amperage or voltage, or duty cycle be-
fore welding.
Single Phase Operation: The unit is supplied with
a 8 AWG power cord. The rated output with 8
AWG is 300 amps, 32 volts at 40% duty cycle. To
achieve 60% duty cycle change cord to 6 AWG.
NOTICE − Exceeding duty cycle can damage unit and
void warranty.
