6.1 list of help codes
code error cause solution
1 Line voltage, idle +/- 15 % Supply line voltage either dropped or
exceeded nominal input setting while idle.
Check voltage supply.
2 Line voltage, c/- 20 % Supply line voltage either dropped or ex-
ceeded 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. Send unit to an Authorized
Repair Station for repair.
4 Thermal switch Switch open - unit overheated. Allow unit to cool down, check for
adequate ventilation and proper
installation of cover.
5 Pressure Air pressure is outside of proper range. Check air supply. Place unit in gas
test mode and check pressure set-
ting. Minimum 60 psi / maximum
95 psi.
6 Fail to fire Arc did not transfer. Arc will repeatedly
"pop" out 3 consecutive times.
Check/replace consumables.
7 Pilot Arc time out (~ 5 seconds) Pilot arc exceeded 5 second limit . Transfer within 5 second limit. Check
ground cable.
8 Torch error Improper assembly of torch consumables.
Torch nozzle making contact with
workpiece at machine power-up.
Check consumables. Remove torch
nozzle from workpiece.
Arch "popped" out three consecutive
times.
Check/replace consumables. If
problem persists replace/repair
torch.
10 Feedback improper Primarily seen if current sensor has failed. Send unit to an Authorized Repair
Station for repair.
11 Primary over-current Converter failure. Send unit to an Authorized Repair
Station for repair.
12 Single phase operation, shut-
down
Exceeded single phase duty cycle rating. Operate within proper duty cycle
rating.
13 OCV (open circuit voltage)
failure
Voltage or current not detected when test
(PIP) is performed.
Send unit to an Authorized Repair
Station for repair.
14 Cabinet temperature Too high, outside of operating limits. Check ventilation around unit and
proper installation of cover.
Check air louvers and any other
openings to ensure that any obstruc-
tion is removed.
15 Bus charger failure Primary bus not up to voltage. Check bus charger. Send unit to an
Authorized Repair Station for repair.
19 Torch trigger early engagement Torch trigger depressed at power up. Release trigger.
20 PIP (Parts in place) no retract Piston did not retract when air applied. Check/clean consumables.
Check air supply.
21 PIP (Parts in place) no continuity Piston did not drop back in place when
signal to solenoid was removed.
Air not flowing from torch:
Check/clean consumables. Ensure
proper installation of consumables.
Air flowing from torch:
High-pressure bypass within
solenoid. Rotate pressure regulator
counterclockwise to reduce pres-
sure to 80 psig.
