And I have to agree, the hardest part to master is getting the fitup just right. Any gaps will make the welding much more difficult, and I am constantly surprised at how bad I can be sometimes at scribing a line then cutting right to it. I have gotten a lot better, but still end up with gaps sometimes. If I end up with no gaps, TIG welding sheet metal becomes a breeze and can be done quite quickly.

Most of us are just as bad following lines. I use my belt sander, files, or a 4 1/2" grinder to get the final fit. And as far as getting the fit perfect? It is way more important on aluminum I think because I've found heat transfer by contact of the panels keeps you from blowing holes. On steel I have no problem dabbing the rod in to fill a 1/8 inch gap if I screw up on the fit. |

Tig or gas
I have found that if you start welding aluminum or steel with a gas tourch , a dillon or a j40 . you will develope great control and you will not have any trouble with tig welding . Your hand to eye movements will improve quickly. That will allow you to do it all.

Anyway, the point is that I am definitely getting better at my gaps and my TIG welding...maybe the 2 go hand in hand. Huh, who'd have thunk it. But I'll definitely keep the copper trick in mind. Does that work with gas welding too, or does the heat just melt the copper?
