Hi - a different Steve here - from central Colorado. I've been reading over forums for a few months now. I'm just about to order a TIG setup.
I have used a 110v mig setup for about 15 years building stuff for personal automotive use (engine swaps, brackets, protection, etc). I also have a 110v plasma cutter.

The work I envision going forward is using 1/4 steel and aluminum for skid plates/protection, interior builds (custom camper stuff) using 16g aluminum and stainless, gas and water tanks, etc. I'm doing this for myself and potentially for custom work for others.

I'm looking at a 200DX and 250EX. It seems at the moment the 200DX would fit the bill. The 250EX would give me the ability to do heavier stuff in the future, but I'm not sure if/when I might need it.

If I go with the 200dx, I might be able to afford a plasma cutter as well.

Anyway - nice to finally be able to post. You folks have been a wealth of information so far
Steve
