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, thermostat(s)

opens, output stops, and cooling

fan runs. Wait fifteen minutes for

unit to cool. Reduce amperage or

duty cycle before welding.
NOTICE − Exceeding duty cycle

can damage unit or gun and void

warranty.
