I always thought this was impossible. Granted, he says it's not for important 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 work. Also, I've been holding out for an affordable AC capable TIG rig to do aluminum. 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?

Based on my experience, the video covers it thoroughly. Note that he
used 309 SS filler wire, which is often used for hard to weld or
unknown steels. I use Inconel 625, which is even more forgiving, but
occasionally see something in the weld that, while not a crack,
doesn't look exactly right. On the other hand, I don't remember ever
having a weld fail. If, as the video says, you avoid highly stressed
and critical joints, you should be fine.

The same advice applies to welding 303 SS. Not supposed to, but it
works as long as you don't put too much faith in the welds.
