I am looking for a source of #6, #8 & #10 threaded weld studs to use in
an
auto body type stud welder.

I can find studs meant for the capacitive discharge machines and have
ordered some to try but it seems like someone would make copper coated
threaded studs similar to the pull pins used with this welder. Does the
copper coat on the pull studs serve any purpose other than preventing the
studs from rusting before use?
I have used common machine screws modified by grinding the head till
the
screwdriver slot is gone and making the head slightly rounded and have
had
pretty good success spot welding them on to 16 gauge steel.

All-thread, cut to length with a simple screw cutter.

The studs need to have a head on them as that is where the stud welder makes
electrical contact with them.
