Duty Cycle is percentage of 10 min- utes that unit can weld at rated load without overheating.
YExceeding duty cycle can damage unit and void warranty.
If a weld module overheats, the High Temperature light goes on and the thermostat opens to stop weld output to that module. Wait fifteen minutes for module to cool. Reduce amperage, voltage, or duty cycle before welding.
This unit has separate duty cycle ratings for each operating mode. If the unit is operated in the dual oper- ator mode, the unit is rated at 40% duty cycle. This means each side of the unit can be operated at 275 am- peres at 40% duty cycle.
When the unit is operated in the single operator mode, the Welder B side (right) is rated at 40% duty cycle (550 A at 40% duty cycle).
