3-2. Duty Cycle And Overheating
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 5-3), and cooling fan runs.
Wait fifteen minutes for unit to cool.
Reduce amperage or duty cycle be-
fore welding.
Y Exceeding duty cycle can
damage unit and void war-
ranty.
