4-2. Duty Cycle And Overheating
208 608-C
Duty Cycle is percentage of 10 min-
utes that unit can weld at rated load
without overheating.
If unit overheats, output stops, the
Overtemperature Light comes On,
and the cooling fan runs. Wait fif-
teen minutes for unit to cool. Re-
duce amperage or duty cycle be-
fore starting to weld again.
Y Exceeding duty cycle can
damage unit and void
warranty.

Volt-ampere curves show minimum and maximum voltage and amperage output capabilities
of welding power source. Curves of other settings fall between curves shown.
