welding body work studs
Simple fix....spend $19.00 at Eastwood.com and get their mig tip that is designed to weld on pull studs.....it spaces electrode from work and is cut out so that you'll be able to see what is happening. There is a tube that you load the stud into then pull the trigger....you'll see when to end the weld.
If you still feel the need to do it the hard way...? You'll have a great desigm to copy.
