22: Welding current High (>112.5%)
This fault will happen if the welding current is more than 12.5% high for
more than 1.5 seconds. This fault can be caused by a fault within the unit,
a short circuit triac. It can also be caused by a poor quality generator with
the supply voltage fluctuating. Try a different generator.
23: Welding current High (>106.25%)
This fault will happen if the welding current is more than 6.25% high for
more than 2 seconds. This fault will normally be caused by a poor quality
generator with the supply voltage fluctuating. Try a different generator.
24: Welding current High (>101.5%)
This fault will happen if the welding current is more than 1.5% high for
more than 3 seconds. This fault will normally be caused by a poor quality
generator with the supply voltage fluctuating. Try a different generator.
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.
