Anwar: there are tones of welding machines out there but they all work the same way. there are a lot of welding machines that has different brand names yet on the inside they have the same exact boards and parts. some machines have different Mosfets parts numbers so I have to keep up with these parts and keep them available in my shop to do these repairs. have a blessed day

In reply to Ken.

Ken: test the Mosfet in circuit? usually will read short in all pins but it is better to test it off board. in my case I developed a way to check it in welding machine through testing the main board that is connected directly to these Mosfets. for more details on checking Mosfet, you can search it on google..have a blessed day

In reply to Tayo.

Tayo: yes it looked better but not the best. LOL. yes, I would say it is about 85 percent usually the fault is Mosfet but sometime I get the main board fried but that hardly every happens...have a blessed day
