ArtMetal

If I had to get one welder for art work, I would get TIG. Multiple metals, very clean welds, metal does NOT have to be added to weld tight fitting pieces together. Mig and stick, and gas for that matter, have their places, but TIG is the most versatile welder. If I had my choice I would have all of them as they each have their own qualities and abilities. I have TIG, stick and gas and use Tig 98% of the time, but I am dealing with cast bronzes. The stick comes out for heavy steel welding and the gas for heating, bending and silver soldering. Tig will give you the cleanest, most even (lots of practice), spatter free welds of any. Gas is right in there on this but it is slower and one needs a great deal of proficiency to make good, solid, nice looking welds. Mig is quick, can be clean (right gas, wire and metal,,,,, and experience), OK penetration, many metals capability.

I could go on but then I repeat myself. Hope this helps a bit
