Proper way to spot weld with a MIG welder
I just got a MIG welder, and my first project is replacing the inner steps on my '56 Chevy pickup. The guide I find online says to drill out the spot welds and put new spot welds in their place.
Anyone out there know the proper way to spot weld with a MIG welder?? How long, for example, do you hold the gun in that one place for a solid spot weld? I thought I read somewhere that you're supposed to "turn up the heat?" What's that mean?
