Re: Broken bolts
Tractor-Holic, that's pretty cool, thanks! I don't have an arc welder, just MIG.
I've never tried it, but I wonder if I could do something similar. Maybe put an old tip in the gun, to avoid damaging a good tip. Retract the wire a bit, and open up the drive roller, so that no wire feeds. Hold the gun tip against the part (remove the nozzle shroud if needed), and pull the trigger. I would think you'd now be flowing current rather like you described, but not adding any metal (which is tricky with MIG, to get heat, but no metal). Has anyone tried this?
