Cutting Capability; Consumable Life - Lincoln Electric TOMAHAWK 375 AIR Service Manual

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 output of
the machine until it cools to the normal operating tem-
perature.
Figure B.1 shows the cut capacity of the TOMAHAWK
375 AIR when cutting mild steel. (The graph plots cut
thickness vs. torch travel speed with a torch standoff of
0.15".)
OPERATION

CONSUMABLE LIFE

The expected life for the TOMAHAWK
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
375 AIR system.
