The best tool I have my welder, want to step it up a bit and take the Tag plunge. Tig will offer me the ability to weld different materials with a finer control of the weld that a Mig lacks somewhat. As I see it the Tig works pretty much like gas welding, however with much better control of the heat.

So my question is about the Tig machine for the users, what brand do you prefer, what to look for, general rule of thumb when buying the machine. Foot control verses finger, what are the consumables filler rod and gas are known what else? The Tig I have in mind Miller Diversion 180 TIG Welder

What other manufactures might compare, I am concerned with the quality not cheap prices just to guide the responses.
Thanks in advance
