FAULT CODES
During operation, the welding unit monitors all aspects of its operation. If
a fault occurs then an error message will be shown.
0: Weld OK
No Fault, weld completed OK.
1: Stuck button on start up
This fault shows when the power is first switched on. Either the Stop,
Start, or a keypad button is stuck in. Free the button to clear the fault.
2: Output fault before weld start
This fault shows when the power is first switched on. The unit will check
the output terminals to make sure no voltage is present when first
switched on. If this fault happens then the internal power relays have
stuck in the closed position. The unit will need to be returned for service.
4: No calibration
This fault happens when the unit has no calibration. This will normally not
show, and if the unit has been calibrated, would be caused by a fault with
the internal memory. Return the unit for service.
5: Case temperature sensor fault (if fitted)
Some units have a case temperature sensor fitted to switch the unit off if
the electronics become too hot. This fault will show if the sensor is faulty.
Return the unit for service.
