Thread: Stud Gun Question

Tweet

I bought a Stud Gun a while back. I was getting it out and using it the other day. And I have a box of pins with no stems on them. I was wondering what are they used for. I was thinking maybe heat shrinking. But you body and fender guys would know for sure. Thanks

Pins no stems ? Do they look like a nail with a rounded/pointed head ? If so thats what you use or at least that's how mine are and work. Pin goes in gun and the head of the pin and gun is pressed firmly against clean metal. The amount of trigger pull time will be 6 to 10 seconds to weld pin to sheet metal, at least that's what mine takes. Slide hammer is used to pull pin thus pulling dent. That's my 2 cents I hope it helps.

If it's just a rounded pin head and no needle, I think those are ment for filling holes. I've used them for that any way.

if very short with a flat head? if they look like a very short pin with a nail head they there used for holding body molding clip on . many times a new panle had no way to hold clips for trim molding. there were was 3 way to put the clips back on pop rivets that were made just for this job and a tip in the gun made only for this that holded rivet up. new molding use to give you very small flat head screws and ends were dip gum . or weld them back on . i called them nail heads ...one thing i never like hitting them with your tip of your fingers when wet sanding. you only had to split the tip of your fingers one or two times at full wet sanding speed to make sure you never did it more then one time. when you get good with the body gun for weld timming key on the pull pins . i would grab the side of the head with side cutters and twist them off. they only have to stick only so good to pull up the dent over time on spot welding on the pins can makes more work

A picture of the "pins with no stems" would probably speed getting an accurate answer, vs guesses about what you mean by "...no stems".

If they look like the pic below they're what Pat is talking about.

used them guns for over 30 years. i have not see any shrinking tip with a hole or a need to put a inscert in the tip that you would grind off for this. before the guns came out i work at a shop that had a spot welder that one end used a plane old washer on its side had a hook tool the washers work better with no plating of any kind on them . this was back when steel was not tin foil . many time the last tool i would use was the gun or the spot welder if i could get in back of the panel with a big spoon.i had some made out of a sping leaf or used a nail pulling flat crow bar or drag a body bar in back to pickup the low spot .last gun i had was made by motor gard ? i think anyways that may of had a shrinking tip with it. many did not .any thing that make heat would shrink steel i used many times a worn out 80 grit sanding disc over were the panle was getting loose after done wipe with damp rag

Yup that must be what they are. Thanks guys.

Good call Pat! As soon as I read that I was like, oh yeah.
