Duty Cycle is percentage of 10 min-
utes that unit can weld at rated load
without overheating.
If unit overheats, high temperature
shutdown light turns On, thermo-
stat(s) opens, output stops, and
cooling fan runs. Wait fifteen min-
utes for unit to cool. Reduce amper-
age or duty cycle before welding.
Y Exceeding duty cycle can
damage unit and void war-
ranty.
