(Figure B.2)
TOMAHAWK™ 1000 front command panel.
FIGURE B.2
When the machine is turned ON, an auto-test is exe-
cuted; during this test all of the LEDs on the Control
Panel light up.
1. Output Current Knob:
For setting the output
current used during cutting. Refer to the Technical
Specification section for more information about
the machine
ʼ
s rated current range.
Air, Gas Purge:
The Output Current Knob com-
pletely rotated counterclockwise enables the air
purge function. A five minute timeout stops the
purge function; this will occur only if the Output
Current Knob remains in the purge mode for an
extended time.
2. Power ON/OFF green LED:
Illuminates when the machine is ON.
Blinking: Input voltage out of range condition. The
machine is disabled: When the input voltage
returns to the correct range, the machine will
restart automatically.
Note:
The Fan may automatically turn OFF if the error
condition persists for more than 2 seconds.

TOMAHAWK™ 1000
LIMITATIONS
Do not exceed output current and duty cycle rating of
machine. Do not use the TOMAHAWK™ 1000 for
pipe thawing.
3. Output red LED:
The cutting torch is energized.
Blinking: Internal auxiliary undervoltage condition.
The machine needs to be turned OFF then ON
again to restart.
4. Thermal yellow LED:
The machine is overheated and the
output has been disabled. This usually occurs
when the duty cycle of the machine has been
exceeded. Leave the machine ON to allow the
internal components to cool. When the thermal
LED turns off, normal operation is again possible.
5. Gas Pressure yellow LED:
The Input Gas pressure is out of
range. The machine will restart automatically
when a correct gas pressure is detected.
To check/adjust the primary gas pressure (see
recommended values in the Technical
Specifications of this manual):
• When this LED illuminates, the machine will
automatically enter into Purge mode for 10 sec-
onds.
• During Purge time verify and adjust the gas
pressure using the gas pressure regulator knob.
• If necessary, also verify and adjust the inlet gas
pressure to the unit.
6. Parts In Place (PIP) yellow LED:
Torch consumables are not attach correctly.
To reset the machine:
• Firmly attach the torch shielding Cup by hand.
Do not over tighten.
• After the torch is restored, the machine will
restart after 5 seconds. During this time the PIP
LED will blink.
Note:
When the LED is blinking, if another PIP
error occurs or if the Torch Trigger pushbutton
is pressed the machine will return to the error
condition: PIP LED returns to steady ON and
the restoring procedure repeats.
• When the PIP LED turns OFF the machine is
ready to operate.
