I've used them, mostly on material 1/4" + in thickness. I had a tough time dialing the juice down to do the thin material. I also used a stainless brush to prescuff the material and for cleaning up the flux. They take some practice, I agree with denverdOn, you're better off with mig or tig. They're OK for repair, but not for a production situation, at least that's my experience. Doug Hodder
