2.08 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-95 is designed for 17%
duty cycle at 85 amps. This means that it has been designed and built to provide the rated amperage, 85 amps, for1.7
minutes out of every 10 minute period. During the other 8.3 minutes of the 10 minute period, the FirePower FP-95
must idle and be allowed to cool. The thermal cutout will operate if the duty cycle is exceeded.
If the unit overheats and the thermostat opens, wait 15 minutes for unit to cool.

Remove dust and metallic particles from the gun conduit by forcing clean, dry compressed air into the conduit once
a week. This will minimize wire feeding problems.
