8: Ambient temperature more than +113
o
F.
The unit has detected that the ambient temperature is very hot, or the sensor has broken, or a
wire has gone open circuit. The unit must be returned to a service agent for repair.
14: Relay failed to latch on weld start
This fault could happen when the start buon is pressed. If the main power relays do not oper-
ate correctly then this fault will be shown. The unit needs to be returned for service.
20: Low output volts (-1.25%)
This fault will happen if the output voltage is 1.25% lower than the set point for more than 3
seconds. The unit needs to be returned for service.
21: High output volts (+1.25%)
This fault will happen if the output voltage is 1.25% higher than the set point for more than 3
seconds.
The unit needs to be returned for service.
22: Excess output volts (+6.25%)
This fault will happen if the welding voltage is 6.25% more than the set point for more than 2
seconds.
The unit needs to be returned for service.
23: Low output current (<2.5A)
This fault will happen if the welding current is below 2.5 amps for more than 3 seconds. It can
be caused by a faulty ng. Try another ng. If this doesn’t clear the fault then there is a
problem inside the unit and it must be returned for repair.
24: Shorted turn detected in ng.
While welding, the unit has detected a sharp increase in welding current. This is normally
caused by a shorted turn happening in the ng. (An increase of 10%). If this happens then it
is most likely a faulty ng. This must be replaced. If the fault persists then it could be a fault
within the unit.
25: User stop buon pressed
The operator has pressed the stop buon.
26: Relay unlatched
During welding, if the main power relay disconnects then this fault will be shown. It could be
caused by the unit being knocked. If the fault persists then the unit should be returned for
repair.
27: Fing open circuit
This fault is shown if the welding cord disconnects from the ng while welding. Follow the
guidelines from the ng manufacturer, reconnect the cord and try welding again.
29: High output current.
This fault is shown if the welding current is above a predened limit for a set me. If the fault
persists then the unit should be returned for repair.
