2-2. Duty Cycle and Overheating
4 Minutes Welding 6 Minutes Resting
Duty Cycle is percentage of 10 min-
utes that unit can weld at rated load
without overheating.
If unit overheats, output stops, a
Help message is displayed (see
Section 7-4), 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.
