Duty Cycle is percentage of 10
minutes that unit can weld at rated
load without overheating.
If unit overheats, thermostat(s)
opens, output stops, and cooling
fan runs. Wait fifteen minutes for
unit to cool. Reduce amperage or
duty cycle before welding.
Exceeding duty cycle can
damage unit and void war-
ranty.
