To ensure correct mounting of SCRs during replacement in your ESAB Welding System, start by cleaning the mounting surfaces. Then, apply a thin coat of Alcoa No. 2 EJC Electrical Joint Compound (or an equivalent) to the SCR mounting surface. Finally, positively locate the SCR in place on the heatsinks.
What to do if SCRs show low resistance in ESAB 453cc?
If SCRs show low resistance in either direction in your ESAB Welding System, it indicates that the SCRs are faulty and need replacement.
