Same think with transmission cover here. Even at 35 amps with a 1/16 tungsten, still having a hard time with it. Going to have to probably break down and order another.Had a slow leak in my oil pan. Seemed like it was coming out of the drain plug so I changed the plug gasket/sill but it continued to leak. Looked all over the pan and didn't see anything leaking down the sides or front but kept cuddling up at the skid plate and dripping at the drain..pulled the pan and drilled bout the spot welds and found a layer of hard crud. I ground it off with a wire wheel and found the culprit!! I figured I would just cut out the section and weld in a new piece of 16ga steel . Well the 40+ years of corrosion under the skid plate had thinned out all of the steel and welding it kept blowing out and wouldn't hold without making bigger holesBroke down and ordered a new one from Toyota. All good now
