Code Error Cause Solution
1 Line voltage, idle +/- 15 % Supply line voltage either dropped
or exceeded nominal input setting.
Check voltage supply.
2 Line voltage, cutting +/- 20 % Supply line voltage either dropped
or exceeded nominal input setting
during a cut.
Check voltage supply.
3 Control bias, +/- 15 V bias split Control transformer not supplying
the proper voltage to the control
circuit
Check transformer and control
board.
4 Thermal switch Switch open - unit overheated. Allow unit to cool down, check
for adequate ventilation.
5 Pressure Air pressure is outside of proper
range.
Check air supply and pressure
setting.
6 Fail to re Arc did not transfer. Check ground cable.
7 Pilot Arc timeout (~ 5 seconds) Pilot arc exceeded 5 second limit . Start within 5 second limit.
8 Torch error Electrode in contact with nozzle
(failed to separate).
Check/replace consumables.
9
10 Feedback improper Primarily seen if Hall sensor is
unplugged.
Check torch - possible nozzle to
work short.
Remove debris from front end of
torch.
Check cable and connection
between current sensor board
and control board.
11 Primary over-current Converter failure. Send unit to an Authorized Re-
pair Station for repair.
12 Single phase operation, shut-
down
Lost (dropped) phase on the pri-
mary supply.
Check line wall disconnect fuses.
13 OCV (open circuit voltage)
failure
Voltage or current not detected
when test (parts in place, PIP) is
performed.
Send unit to an Authorized Re-
pair Station for repair.
14 Cabinet temperature Too high, outside of operating
limits.
Check ventilation around unit.
Check air louvers and any other
openings to ensure that any ob-
struction is removed.
15 Bus charger failure Primary bus not up to voltage. Check bus charger.

20 PIP (Parts in place) no retract Piston did not retract when air ap-
plied.
Check/clean consumables.
Check air supply.
21 PIP (Parts in place) no continuity Piston did not drop back in place
when air was removed.
Check/clean consumables.
