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,
Over Temp is displayed, and the
cooling fan runs. Wait fifteen min-
utes for unit to cool. Reduce amper-
age or duty cycle before starting to
weld again.
NOTICE − Exceeding duty cycle
can damage unit and void warranty.
