Wanted Stud Welder

That's what I will probably do.. I was a little worried about the heat with using nail method. . And I think I even have a bunch of 6d nails. . Thanks
If you have a MIG welder, you can try what I used to do before I got a Stud welder. Try grinding the points off of a 6 pennt steel nail and tack welding it in the dent. Then pull on the nail and cut/grind when done. It doesn't work bad.
