3-2. Duty Cycle And Overheating
Continuous Welding
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 fo
r
unit to cool. Reduce amperage o
r
duty cycle before welding.
Y Exceeding duty cycle can
damage unit and void
warranty.
