List of Help Codes

Code Error
1 Line voltage, idle +/- 15 %
2 Line voltage, cutting +/- 20 %
3 Control bias, +/- 15 V bias split
4 Thermal switch
5 Pressure
6 Fail to fire
7 Pilot Arc time out (~ 5 seconds)
8 Torch error
10 Feedback improper
11 Primary over-current
12 Single phase operation, shut-
down
13 OCV (open circuit voltage)
failure
14 Cabinet temperature
15 Bus charger failure
19 Torch trigger early engagement
20 PIP (Parts in place) no retract
21 PIP (Parts in place) no continuity
Cause
Supply line voltage either dropped or
exceeded nominal input setting while idle.
Supply line voltage either dropped or ex-
ceeded 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. Arc will repeatedly
"pop" out 3 consecutive times.
Pilot arc exceeded 5 second limit .
Improper assembly of torch consumables.
Torch nozzle making contact with
workpiece at machine power-up.
Arch "popped" out three consecutive
times.
Primarily seen if current sensor has failed.
Converter failure.
Exceeded single phase duty cycle rating.
Voltage or current not detected when test
(PIP) is performed.
Too high, outside of operating limits.
Primary bus not up to voltage.
Torch trigger depressed at power up.
Piston did not retract when air applied.
Piston did not drop back in place when
signal to solenoid was removed.

Solution
Check voltage supply.
Check voltage supply.
Check transformer and control
board. Send unit to an Authorized
Repair Station for repair.
Allow unit to cool down, check for
adequate ventilation and proper
installation of cover.
Check air supply. Place unit in gas
test mode and check pressure set-
ting. Minimum 60 psi / maximum
95 psi.
Check/replace consumables.
Transfer within 5 second limit. Check
ground cable.
Check consumables. Remove torch
nozzle from workpiece.
Check/replace consumables. If
problem persists replace/repair
torch.
Send unit to an Authorized Repair
Station for repair.
Send unit to an Authorized Repair
Station for repair.
Operate within proper duty cycle
rating.
Send unit to an Authorized Repair
Station for repair.
Check ventilation around unit and
proper installation of cover.
Check air louvers and any other
openings to ensure that any obstruc-
tion is removed.
Check bus charger. Send unit to an
Authorized Repair Station for repair.
Release trigger.
Check/clean consumables.
Check air supply.
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.
