CUTTING CAPABILITY
The TOMAHAWK™ 375 AIR 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 out-
put of the machine until it cools to the normal operat-
ing temperature.
Figure B.1 shows the cut capacity of the TOMA-
HAWK™ 375 AIR 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™ 375 AIR'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 indi-
cate 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™
375 AIR system.
