cause
Supply line voltage either dropped
or exceeded nominal input setting.
Supply line voltage either dropped
or exceeded nominal input setting
during a cut.
Control transformer not supplying
the proper voltage to the control
circuit
Switch open - unit overheated.
Air pressure is outside of proper
range.
Arc did not transfer.
Pilot arc exceeded 5 second limit .
Electrode in contact with nozzle
(failed to separate).
Primarily seen if Hall sensor is
unplugged.
Check torch - possible nozzle to
work short.
Remove debris from front end of
torch.
Converter failure.
Lost (dropped) phase on the pri-
mary supply.
Voltage or current not detected
when test (parts in place, PIP) is
performed.
Too high, outside of operating
limits.
Primary bus not up to voltage.
Piston did not retract when air ap-
plied.
when air was removed.

solution
Check voltage supply.
Check voltage supply.
Check transformer and control
board.
Allow unit to cool down, check
for adequate ventilation.
Check air supply and pressure
setting.
Check ground cable.
Start within 5 second limit.
Check/replace consumables.
Check cable and connection
between current sensor board
and control board.
Send unit to an Authorized Re-
pair Station for repair.
Check line wall disconnect fuses.
Send unit to an Authorized Re-
pair Station for repair.
Check ventilation around unit.
Check air louvers and any other
openings to ensure that any ob-
struction is removed.
Check bus charger.
Check/clean consumables.
Check air supply.
