CUTTING CAPABILITY

The PRO-CUT 80 is rated at 80 amps, at 60% duty cycle on a 10 minute basis (runs 80 amps for 6 minutes, then idling for 4 minutes) or 60 amps, at 100% duty cycle (continuous use). If the duty cycle is exceeded, a thermal protector will shut off the output of the machine until it cools to the normal operating temperature.

Figure B.1 shows the cut capacity of the PRO-CUT 80 when cutting mild steel. The graph plots cut thickness vs. torch travel speed with a torch standoff of 0.15"(3.8mm). Example: 0.5”(12.7mm) material may be cut at a setting of 55 amps at an approximate speed of 25”/m(635mm/m) or at a setting of 80 amps at an approximate speed of 35”/m(889mm/m).

CONSUMABLE LIFE

The expected life for the PRO-CUT 80’s electrode under normal conditions is approximately 30 to 40 minutes of cutting time at the machine’s maximum rated output. An erosion of approximately 1/16" in the electrode tip is typ- ical for the end of electrode life, however, the electrode may last longer. A sustained green and erratic arc will indicate definite electrode failure and both the electrode and nozzle should be replaced immediately.

It is recommended that consumables (electrode and nozzle) be replaced in complete sets. This will maximize the performance of the PRO-CUT system.
