I have two spot welders with the operational controlls beyond repair. My question is; has anyone bypassed the programmable controls and just turned on the ignitrons with a stop switch? If so how? Anyone know where I could get any information. I tried google and the only thing I found was they work similar to a SCR.
TIA

I would get some big hockey puck SCRs and eliminate the Ignitrons completely.
