4-2. 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 and void warranty.
