SCRS Quick Tip: Welder Setup STRSW

In this video from the Society of Collision Repair Specialists, Gary Wano Jr. of GW and Son is joined by T.J. O’Rourke of I-CAR to discuss why spot resistance welding requires more than just turning on the machine and pulling the trigger — it demands testing for precision and adherence to OEM procedures. 

Learn key adjustments every technician needs to understand around amperage, electrode squeeze force, and weld time.  While modern welders with auto-set features provide convenience, it does not eliminate the importance of practice welds and destructive testing before touching the vehicle. 

O’Rourke highlights common mistakes such as excessive squeeze force squishing out the weld pool or incorrect amperage blowing holes in material. He reminds technicians to always reference the manufacturer’s published procedures, especially when working with high-strength and ultra-high-strength steels. From proper setup to testing techniques, this discussion reinforces attention to detail and following OEM specs for safe, high-quality repairs.
