I used to be able to resistance welding bandsaw blades. But I am having problems now. I am now only successful @10 per cent of the time. I am not having problems with annealing or tempering. My welds are burning through.
I have cleaned the clamps, checked for their movement and everything the manual says. The blades are cleaned, they're cut square and I have tried all the compression settings.
Each time I try, it will get red at the back, then the heat starts moving toward the teeth. By the time that area is hot and compression starts, things start burning.
Any suggestions?
