4-3. Welding Power Source 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 voltage, or
duty cycle before welding.
NOTICE − Exceeding duty cycle can
damage unit or gun and void warranty.
