3-2. Duty Cycle And Overheating
Duty Cycle is percentage of 10
minutes that unit can weld at rated
load without overheating.
If unit overheats, output stops, and
cooling fan runs. Wait fifteen
minutes for unit to cool. Reduce
amperage or duty cycle before
welding.
Y Exceeding duty cycle can
damage unit and void
warranty.
