In this episode, I take a 40yr old Montgomery Ward 230v 140amp AC/DC ARC welder and give it some TLC. I give it a good clean, replace the aging diodes with 4, Vishay Standard Recovery Diodes (70HF Series) from [ Ссылка ].

The welder could use a few new or really nice bits. If you know of a source or have the [internal} part that moves up and down when you adjust the amps, or a manual, please leave a comment below or DM me.

Thank you to www.weldingweb.com it a great source for information.
