Duty Cycle is percentage of 10 min-
utes that unit can weld at rated load
without overheating.
If unit overheats, output stops, the
Overtemperature Light comes On,
and the cooling fan runs. Wait fif-
teen minutes for unit to cool. Re-
duce amperage or duty cycle be-
fore starting to weld again.
NOTICE − Exceeding duty cycle
can damage unit and void warranty.
