Touch the electrode to rivet end and the entire rivet heats completely through. Cherry to white hot. Then hit it with the air gun.
A lot simpler than using a torch and sure expansion in the hole.

OK, so you're saying to put the rod onto the end of the rivet and hold it there without creating an arc? How long should it take to heat up a 1/4" rivet?
