ANALYSIS
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 peri-
od of time ( more than two days ).
2. In the process of welding

SOLUTIONS
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.
1. Recover the phase.
2. Replace the switch.
3. Replace or repair the fan.
4. Check the connection.
1. See No. 1
2. Replace the switch.
1. Replace it with a bigger capacity one.
2. Replace it with another one in conformity with the
requirement.
3 &4. Remove the oxide skin and tighten it.
1. Not failure. Trip caused by the main power filter's capacity
charging. Switch on the main power source.
