One of the land cruiser logo stud holes had rusted through an perforated all around. About a 2.5×2.5″ section.
This went really easy.
Im getting lots better about controlling the heat. Pretty much only do short tacks now. Let the weld cool before I put down another one.
I even checked from the back in bright sun and no pinholes. I chalk this up to my using more heat and hitting the metal in shorter bursts. Got better penetration, no pinholes. Awesome!
