best way to connect armorerers pliars with the welder? in General Questions Posted December 27, 2019 · Report reply I would suggest brazing the copper wire on with a bit of brass or silver solder and use borax as flux, that should make it stick. You'd need to use a torch as your heat source instead of a soldering iron. You could also try to use your jewelry welder to weld a small bolt onto the pliers. It would probably take multiple welds to get a decent electrical connection though. Brazing is likely a better method.
