That time a quarter panel weld blew through on a classic Mustang

I was in my shop in Dayton last spring, working on a 1967 Mustang's rear quarter. I set my MIG welder to what I always used for that gauge steel, but on the first pass, it blew a hole the size of a dime right through the panel. I stopped, cleaned the area, and cut a small patch from scrap. I turned the voltage down a full volt and did a series of quick tack welds around the patch, letting it cool between each one. It saved the panel and the job. Has anyone else had a go-to setting fail on a classic car?

Ever feel like the metal just decides it's had enough? I mean, my settings have betrayed me more times than I'd like to admit.

Ever have that happen on a newer car? Metal quality is just different now, so old settings can burn right through. Glad you caught it and fixed it.

Seems like everything's made thinner and cheaper these days.
