Part identification.

[Mr Smiles]

I’ve been working on electronics for a long time as a hobby. I currently am working on a Lincoln welder and I need identification of a part of you can. Thinking part of the part # is gone due to the failure. Any help would be appreciated immensely!

Welcome to ETO, Mr S!

Looks like a blown bridge rectifier. The "PR501" didn't google, however, to anything useful...

Thanks fellas. The only bridge rectifiers I’m accustomed to are the old square box style used in pinball machines that I used to work on. Again thank you very much.
