LIMITATIONS
Do not exceed output current and duty cycle rating of machine. Do not use the TOMAHAWK™ 625 for pipe thawing.
If the arc turns off while cutting using low input volt- age, that is below 208V, lower the air pressure by adjusting the regulator knob.
When using with the Outback 180, gouging is not rec- ommended.

1.Output Current Knob: Potentiometer used to set the output current used during cutting. Refer to the Technical Specification section for more infor- mation about the machine’s rated current range.
Air Purge: The Output Current Knob completely 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.
3.Output red LED: See the following table.
4.Thermal yellow LED: See the following table.
LEDs | Description | |
Output | Thermal |
|
(Red) | (Yellow) |
|
On | Off | The cutting torch is energized. |
On | On | Part in place error: the retaining |
|
| cap is not properly Attached. |
|
| To restore the machine: |
|
| • Install the torch retaining cap |
|
| firmly in place. |
|
| • Wait for 5 seconds; during this |
|
| time the output and thermal |
|
| LED’s blinks alternately. |
|
| • After 5 seconds the machine is |
|
| automatically restored and ready |
|
| to operate. |
|
|
|
Off | On | 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 pos- |
|
| sible. |
|
|
|
Off | Blink | Power undervoltage error: the |
|
| machine is disabled. When the |
|
| power returns to the correct range, |
|
| the machine will restart automati- |
|
| cally. |
|
|
|
Blink | Off | Low air pressure error. |
|
| To check / adjust the air pressure |
|
| (see recommended values in the |
|
| Technical Specifications of this |
|
| manual): |
|
| • Put the machine in Purge mode |
|
| [1]. |
|
| • Check and adjust the air pres- |
|
| sure using the pressure gauge |
|
| and air pressure regulator knob |
|
| [6]. |
|
| • If necessary, check and adjust |
|
| also the inlet air pressure by |
|
| adjusting the external compres- |
|
| sor. |
