This is cool stuff to me. Ive long thought about a tig process that automatically feeds the wire. Ive seen that tig tip also. My realy thought about this was actually printing up parts. If you can put a welded micro dot down, you could easily fabricate any part from metal using a 3d welder. As an inventor this is something I dream about, lol. They probably already have this kinda stuff already. I just never heard of it. It would be so cool just to print out any part from a cad drawing. Without having to machine it. You could do some really complex inner work that you cant do with machining. Anyways, thanks you all for the posts.
