Randy -

I'm gonna assume you're using a MIG welder on the cooler. Provided the metal isn't beyond salvation, I've found that burn-through can be eliminated by backing up the weld area with a piece of copper. There are spoons available specifically for that purpose, but I've mashed a piece of copper pipe in a pinch. Just be sure the copper is clean and bright and conforms to the shape of the piece being welded. I don't understand the science behind it all, but it works.
