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 95 FC 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 FC 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.
2.08 MIG Gun Maintenance
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.
