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. It will normally be caused by a poor quality generator with the supply voltage fluctuating.
Try a different generator.
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. This fault is normally caused by a fault within the unit, a short circuit triac. The unit must
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 fitting. Try another fitting. 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 fitting.
While welding, the unit has detected a sharp increase in welding current. This is normally caused
by a shorted turn happening in the fitting. (An increase OF 10%). If this happens then it is most
likely a faulty fitting. This must be replaced. If the fault persists then it could be a fault within the
unit.
25: User stop button pressed
The operator has pressed the stop button.
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 or a temporary dip in the power supply. If the fault persists then
the unit should be returned for repair.
27: Fitting open circuit
This fault is shown if the output lead disconnects from the fitting while welding. Follow the
guidelines from the fitting manufacturer, reconnect the lead and try welding again.
127: Power off failure.
If the power is turned off while the unit is welding, this fault will be recorded to the datalog.
