Duty Cycle
Duty Cycle is simply the amount of time out of a 10 minute period in which the unit can operate. For example, this unit has a duty cycle of 25%. This means that the
unit can be operated for 2.5 minutes out of 10 minutes at 115 Amps maximum output while operating on 120V, and for 2.5 minutes out of 10 minutes at 180A while
operating on 240V. This may be continuously, or intermittently during the 10 minute period of time. This rating standard (United States) is based on a maximum ambi-
ent temperature of 40 C. Operating above this point, or at lower temperatures with high humidity may reduce the duty cycle rating. Of course, the duty cycle may in-
crease somewhat as ambient temperature drops. Regardless, this unit
’
s duty cycle is not controlled by a timer. Rather, this unit is equipped with a heat sensor located
on a heat sink near the critical power components of the welder. If the operating temperature of the unit is exceeded, welding output will stop and an over

warning light/error code will be displayed on the panel. If a duty cycle event is registered, do not turn the unit off! Allow the welder to continue to run at idle for at least
10

. Even if the unit resets, allow the unit to cool for a full 15
minutes, or the duty cycle will be more quickly triggered since the unit resets just below the heat threshold. The fan(s) must continue to run for a full 15 minutes to cool
the unit properly after the duty cycle shut down has occurred.
After 15 minutes of cooling, you may switch the unit off if you are finished welding. If the unit does not
automatically reset after 15 minutes, turn the unit off. Wait for 15 seconds before turning the machine back on. If the unit does not reset, contact technical support for
further advice and assistance. As a best practice, when you have completed welding and have been welding continuously for extended periods of time, keep your unit
on for 10 additional minutes without welding to allow it to cool.
The intentional and/or repeated triggering of the duty cycle protection feature on this unit will shorten the lifespan of the unit
’
s electronics and can weaken internal com-
ponents. The effect of overheating your unit repeatedly takes a cumulative toll on the unit.
