4 Minutes Welding 6 Minutes Resting
6 Minutes Welding 4 Minutes Resting
Duty Cycle is percentage of 10 min-
utes 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
voltage, or duty cycle before
welding.
Y Exceeding duty cycle can
damage unit and void
warranty.
