AIR COMPRESSOR

The Tomahawk 375 Air has an internal air compressor
®
so the machine does not need an external air supply to
cut metal. The aluminum alloy compressor is driven by
a single phase ½ horse power motor. The motor is
powered by the input line voltage (208-230VAC) via a
triac circuit located on the inverter board.
There is also the option to supply the Tomahawk using
®
an external air source. If an external air supply is used
it is necessary to turn-off the internal compressor using
the switch located on the front panel of the Tomahawk .
®
When using the internal compressor it is necessary to
remove the external air supply hose from the
Tomahawk .
