Duty cycle

The duty cycle of a welding power source is the percentage of a ten (10) minute period that it can be
operated at a given output without causing overheating and damage to the unit. If the welding amperes
decrease, the duty cycle increases. If the welding amperes are increased beyond the rated output, the duty
cycle will decrease.
WARNING: Exceeding the duty cycle ratings will cause the thermal overload
protection circuit to become energized and shut down the output until has cooled
to normal operating temperature
NOTICE£º
Due to variations that can occur in manufacture products, claimed performance, voltages, ratings, all
capacities, measurements, dimensions and weights quoted are approximate only. Achievable capacities and
ratings in use and operation will depend upon correct installation, use, applications, maintenance and service.
