I bit the bullit about 18months ago and purchased a Miller 150STH Tig welder, it also doubles as a stick welder, I am reasonably experienced with Tigs as I used to work as a stainless steel "Sail buggy fabricator, it takes a bit of time to get the speed etc right as the Tigs penetrate quite well its a bit of an art to avoid undercutting but I prefer a good weld and some undercutting doesnt bother me as long as the weld is strong, on reasonably thin metal its quite easy to see the weld penetrating right through the material.

This welder doesnt do aluminiumm and to be honest I dont want to learn to do aluminium when I need to do that I get the experts to do it. Miller make a nice Mig that you can automatically adjust for different jobs and it would be good for doing light panel, chassis and heavier work like 5/16" plate, and if you are a novice I would concentrate on not moving fast and getting a good hot weld, as its all to easy on heavier metal to get a weld that just sits on the surface and virtually falls off.

Having said that if you are doing heavier work and a lot of tacking the Mig may be better, but I love my Tig, so the answer might be to have both!
