Duty Cycle is percentage of 10 min-
utes that unit can weld at rated load
without overheating.
If unit overheats, thermostat opens,
output stops, light goes on (CE
Models Only), and cooling fans run.
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.
