CUTTING CAPABILITY
The TOMAHAWK™ 625 is rated at 40 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 TOMA-
HAWK™ 625 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 TOMAHAWK™ 625's elec-
trode under normal operating conditions is approxi-
mately 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 TOMAHAWK™
625 system.
