Thoughts on this approach? Better suggestions...?
A true tack weld is made to break off if needed or hold things in position to be welded.

A series of tacks would be a series of welds made to break off.

I weld exhaust with an SP100 turned down C 3 .
I start at the top and make my way down. One pass each side.
Make a dry pass to see where the gun will fit if its on the car.
