Fault Code Key
Error
Code
Error Remedy / Comments
2-1 Missing AC Phase Blown fuse, Broken or loose connection on power cable
2-2 Wrong input voltage
Inverter(s) not configured correctly for input voltage;
Poor power quality (brownouts, dropouts); Input power capacity / wiring
too small causing voltage drop; broken or loose power cable connec-
tions.
2-3
Inverter or Pilot Regulator Over
Temperature
2-4 Power Supply not Ready
2-5 DC Output Low
Less than 60 VDC; Defective inverter, shorted output; CCM voltage sense
(J6) wire open or disconnected. Negative lead short to gnd. Shorted
chopper (100-300A only).
2-6 Inverter input fault
Capacitor bank voltage imbalance (400-460-600V only) or inverter
primary switching circuit overcurrent. If occasional may be line voltage
surge; remove power to reset. If persists defective inverter; LED on
inverter indicate which one.
2-7 Unexpected current
Current above 20A in work or pilot leads before pilot ignition; Possible
shorted torch; Defective current sensor.
2-8 Unexpected current in pilot circuit
Current above 5A in pilot circuit; wrong or mismatched consumables;
Pilot lead shorted to negative in torch tube; Possible shorted torch
2-9 Unexpected current in work lead
Current above 5A in work lead; Short to chassis in RAS; Negative lead
short to ground.

3-1 Gas Control Communication fault. Cannot establish Communication with gas control. If Gas Control is
GCM 200 or (rest of text unchanged.)
3-2 Gas Control reply fault. Connection was established but (rest of text unchanged.)
3-3 Gas Supply Pressure out of range.
If Gas Control is GCM 200 or GCM 1000 Plasma may be less than 51
PSI; faulty or disconnected pressure SW. If GCM
2010 is rev AG or GCM2000 is rev AC (or later) or Gas Control has been
updated with 19X2219_AG (or later) PCB then Plasma or Shield supply
pressure may be outside the range of 105-135 PSI.
Unplugged or faulty pressure sensor; faulty gas control PCB.
3-4 Gas Control not ready Purging; Not in RUN mode; Gas Control faulty, replace PCB
3-5 Gas Control Protocol Error Verify Firmware revison for compatiblity with CCM
3-6 Reserved No information available; Contact customer service
3-7 Gas Control sequencing error Verify Firmware revison for compatiblity with CCM
3-8 Gas Control Type Mismatch
CCM must be Ultracut type for GCM 2010; Autocut type for GCM 2000,
GCM 1000 or GCM 200
3-9 Gas Control Command fault Verify Firmware revison for compatiblity with CCM
