I always thought this was impossible. Granted, he says it's not for importa nt structural welds, but still, this opens up a new world to me. I'm pretty so-so machining, and 12L14 just makes it so much easier to do passable wor k. Also, I've been holding out for an affordable AC capable TIG rig to do a luminum. If I can do this kind of welding on leaded steel, I'm a very happy camper, and the TIG welder is coming sooner rather than later.
Thoughts?
