Cutting Capability; Consumable Life - Lincoln Electric PRO-CUT 25 SVM149-A Service Manual

B-4

CUTTING CAPABILITY

The PRO-CUT 25 is rated at 25 amps, at 35% duty cycle on a 10 minute basis. 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 25 when cutting mild steel. (The graph plots cut thickness vs.
torch travel speed with a torch standoff of 0.15".)

CONSUMABLE LIFE

The expected life for the PRO-CUT 25's electrode under normal operating conditions is approximately 1000
starts/cuts. An erosion of .060" is typical for end of electrode life, however, the electrode life may last longer. A
green and erratic arc will indicate definite electrode failure and the electrode should be replaced immediately.
It is recommended that consumables be replaced in complete sets. (Example: Electrode and Nozzle). This will
maximize the performance of the PRO-CUT 25 system.
