4-3. Duty Cycle And Overheating

Duty Cycle is percentage of 10 minutes 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.
