Yogesh: thank you very much. it depends on the size. they is no basific voltage reading. some machines 60, some 80 and bigger machines usually 120 volts. but from experience getting the voltages on the output does not mean the machine is working out fine. it has to be tested by doing the actual welding on the machine to find out. have a blessed day

What are basic output voltage of this type of machine?

I am glad you are learning about IGBT's. they are a lot of videos on youtube that can give you a lot of information about them. they are very interesting and learning about them would help you or any technician to repair things..have a blessed day

I'm learning a lot about IGBTs from you, Waleed. I guess the fan was the initial cause for the IGBTs to go short.

Thanks for sharing. You´ve said that one fin was missing, but the picture show absence of two fins.
