I bought an H&S 4500 spot welder at a garage sale. It's the kind that welds wires onto auto body parts for pulling dents. Came without tips. Haven't yet found a local supplier...no sweat...
1/2" bolt and a few minutes on the lathe and I have a tip.I've tried welding pieces of welding wire, nails etc. to sheet metal. All I've succeeded in doing is welding the steel tip to the work piece.
My first thought is that I need to make the tip out of something that won't stick to the weld??? Thought about copper, but that's mighty soft. Maybe copper plate the steel?
Ideas? thanks, mike
