turning very slowly.
No no-load voltage.
Electrode Holder and Cable
getting hot;“+” “-” polar
sockets becoming hot.
Power source tripping.
Others
1. Bad power ventilation lead to
over-heat protection
2. Circumstance temperature is
too high.
3. Using over the rated duty-cycle.
1. Potentiometer broken (current
regulation).
1. Scarcity of phase.
2. Switch broken.
3. Fan broken.
4. Wire broken or falling off.
1. Welder getting overheated.
2. Switch broken.
1. Electrode Holder’s capacity is
too small.
2. Cable is of small size.
3. Replace it with another one in
conformity with the requirement.
4. Bigger resistance between the
electrode holder and the cable.
1. Resume power over a long
period of time ( more than two
days ).
2. In the process of welding
1. Improve the ventilation condition.
2. It will automatically recover when the temperature low down.
3. It will automatically recover when the temperature low down.
1. Replace the potentiometer.
