3-3. Duty Cycle And Overheating
Duty Cycle is percentage of 10 min- utes that unit can weld at rated load without overheating.
If unit overheats, output stops, a Help message is displayed and cooling fan runs. Wait fifteen min- utes for unit to cool. Reduce amper- age or voltage, or duty cycle before welding.
. Single Phase Operation: The
unit is supplied with a 8 AWG power cord. The rated output with 8 AWG is 300 amps, 32 volts at 40% duty cycle. To achieve 60% duty cycle change cord to 6 AWG.
NOTICE − Exceeding duty cycle can damage unit and void warranty.
