4-3. 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.

NOTICE − Exceeding duty cycle

can damage unit and void warranty.
