When the machine is turned ON, an auto-test is executed; 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's rated
current range.
AIR, GAS 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.
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.
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
2
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
4
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 seconds.
5
During Purge time verify and adjust the gas pressure using
the gas pressure regulator knob.
6
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.
