How to repair welding machine?

One like that? A big hammer.

 

In a case like this it is very useful to have both a circuit diagram and a block diagram with a description of how it works. Then a description of what is not working is required. After that , a study of the circuit to see which parts failing would produce the problem seen.

If none of those items are available then the process is different, which is first inspect for failed connections and then check for failed parts. This method is far slower than using the understanding of how it works to see where the problem lies.

 

I think I see the problem..............
