A door skin weld pulled through on a 2018 Silverado job in Boise

I was doing a full door skin replacement on a 2018 Silverado at my shop in Boise, and my spot welder pulled right through the new panel on the third weld. I realized the welder's amperage was set too high for the gauge. I turned it down to 3.5 and used a copper spoon behind the next spot, which worked perfectly. Anyone have a better trick for preventing blow-through on newer, thinner door skins?

Been there! A copper spoon is the right move for sure. Sometimes I'll also put a little extra pressure on the gun to help it bite without blowing out.

Read copper can tarnish and affect flavor?
