The contacts are not used in a face to face position. They are used as 2 separate spot welds at the same time. I guess it like stitch welding? I have read the down fall is that the panels have to be very tight on fit up or the spot weld wont hold. So you need to clamp the panels tight, as the current has to flow through the metal back to a ground (the other contact) to complete the circuit.How does it clamp the metal or do you hold and electrode on each side?
I did use a Miller hand held spot welder with the long reach arms to put the front end on a 20th. Anniversary mustang my X crashed. It got crashed again and had to go on frame machine and the spots held. I did lots of testing before we started though.
One time at the factory we welded the whole floor for the Aerostar van for Ford. They did a tear down at Ford and found cold spot welds and we ended up buying every 1/8" pop rivet in stock. Ford recalled a bunch of them and they pulled the carpet up and put a bunch of pop rivets in.
It is amazing how little you get per spot weld. Toyota tells you up front you get $.03 per spot weld. You have to cool the water pay for labor, equipment and tips from that. Did find that if you sent the tips and have them cryogenic treated they last many times longer.
Would be interested seeing how it works.
