2.07 Duty Cycle
Duty Cycle is the amount of arc-on time (actual welding time) during any 10 minute period that a machine can operate at it’s rated
output without damaging internal components. For example, the Firepower FP 135 is designed for 20% duty cycle at 117 amps. This
means that it has been designed and built to provide the rated amperage, 117 amps, for 2 minutes out of every 10 minute period. During the other 8 minutes of the 10 minute period, the Firepower FP 135 must idle and be allowed to cool. The thermal cutout will operate
if the duty cycle is exceeded.
The Firepower FP 125 is designed for 19% duty cycle at 90 Amps.
The Firepower FP 135 is designed for 20% duty cycle at 117 Amps.
The Firepower FP 165 is designed for 18% duty cycle at 140 Amps.
If the unit overheats and the thermostat opens, wait 15 minutes for unit to cool.
