Duty Cycle is percentage of 10 min-

 

 

 

 

 

 

 

 

utes that unit can weld at rated load

 

 

 

 

 

 

 

 

without overheating.

 

 

 

 

 

 

 

 

 

If unit

overheats,

thermostat(s)

fan runs. Wait fifteen minutes for unit to cool. Reduce amperage or duty cycle before welding.

NOTICE − Exceeding duty cycle can damage unit and void warranty.
