Today is a first for me. I’ve welded 14 gauge lines up on an aluminum transmission cooler off a Toyota Camry before, and I welded a bunch of 1/8 plate but today is the thickest I’ve done before. I don’t have any pictures as of the moment but a client is having me build a transom riser that’s constructed out of 3/16” aluminum plate and 2”x1/4” aluminum square tube. No helium available and my machine is limited to 230 max AC. This is going to be fun!
