Hello. I have a problem with the welding machine namely during welding suddenly turned off. It has several meat and was used a second time. Last welding lasted 10 minutes with breaks and only 2.5mm electrode consumed. and exactly I did not weld, I just set the right ampere for the thin sheet ... I thought that it overheated and turned off, though it had nothing because it was cold. I waited for hours but did not turn on. What could break? I will add that I have a welding machine from a neighbor and I need to fix it as soon as possible.
