My ac/dc tig has been repaired twice and has cost me 600 euro in total to repair after spending 1100 euro 2 years ago on the machine!I have learned my lesson since and bought a kemmpi mig and good quality mma inverter since but I still want to repair my parweld machine because a quality ac/dc machine would cost at least 2500 euro I'm told
I removed the card thats blown and noticed the voltage regulator exploded and the nearby capacitor is half cooked and the other black negative capacitors are half melted.
I noticed while I was welding I was getting a huge burst of high current and when I glimsed at the clock in the machine it read 600 amps!I reckon this current would have caused the damage but what caused the current to buid up like that I dont understand
I also noticed that When I ripped the tig torch the little remote switch wires were melted together and stuck to the brass fitting on the gas pipe.I'm not an expert but I think the welding current goes through that fitting.
I'm wondering Is it me or is it the welders fault!I have a number of theorys!
It could be the fact that my workshop has insufficiant power because of the light cable coming from the house to the workshop which is 70 metres from the house
I maybe have been overloading the machine welding for long periods at a time but I often welded for much longer in college with the air cooled fronius!
I'm lost alot of welding jobs over the machine and It has my head annoyed.Advice would be geatly appriciated.Thank you!
