    Do you start dollying the bead asap?

    Ex: Spot weld, quickly dolly, let cool slowly, go to another area of the panel and repeat. Keep repeating entire seam is filled with spot welds.. right?

    I like the cut off wheel trick on a die grinder. Works great for removing spot welds as well.

    Thanks for your time

    I use 3M 2" discs on my die grinder, I don't remember what they are made of but they are designed to run cooler you can even grind with them wet, which really helps preventing heat build up.

    what about using reverse polarity? wouldn't that put less heat into the sheet metal?
