I have a little Sears 105 Amp MIG machine and it does wonders on steel. It says 20% duty cycle but I 've used it for hours at near capacity amps at 75%.
Anyway I tried some aluminum wire and it does feed okay but trying to get an arc on even thin material is a joke. The wire just welds to the base metal.
I can't afford a real TIG machine right now. Now comes the hairbrained idea. I have a 225 amp AC stick machine. Can I disconnect the MIG machine electrodes from the unit and feed the stick macine output to the MIG torch?
What would be the result? Would I have a better shot at welding some aluminum? I'd have twice the amps, ac which is better for aluminum, yes? And an Argon shield.
