4-2. Welding Power Source Duty Cycle And Overheating

4 Minutes Welding 6 Minutes Resting

6 Minutes Welding 4 Minutes Resting

Duty Cycle is percentage of 10

minutes that unit can weld at rated

load without overheating.

If unit overheats, Thermistor (T)

opens, output stops, and cooling

fan runs. Wait fifteen minutes for

unit to cool. Reduce amperage or

voltage, or duty cycle before

welding.

Y Exceeding duty cycle can

damage unit and void

warranty.
