There was a thread like this over on WW and I was really bored today and decided to see if my Weldernator had enough finesse to handle this sort of thing. I would have tried to tackle a pop can but I only have DC- to play with. These blades are .021" thick. Filler wire was .035" ER70-S6. Was all I had.
Setup:
Blades were clamped to a large block of aluminum for a heat sink backing.
Max amps @ minimum setting. (Really have no idea the amount of current I was using.)
Foot Pedal: 1/2-2/3
Tungsten: 3/32" 2% Lanthanated
Argon: ~12-15CFH
I struck up the arc on the aluminum backer then moved over onto the blades. For my first attempt at welding razor blades I'm pretty happy with it. I know these are pretty thick blades, but I don't think I have enough amp control to do regular single edge blades.
