Hi this is my first post (apologies if its not in the right place and for the length I know is coming lol).

Im looking for an ac/dc tig welder that will, most importantly, offer good control on the low-end for detailed work in metal art like tacking/seaming thin (28-30 gauge min maybe) sheet and welding small parts like, for example, securing an 1/8" piece of round steel rod to a 3/8" ball bearing...in this neighborhood. So far my pieces have been only steel as I do not have A/C capability (but would like decent low-end on aluminum, as well), and Ive been using an old flux core mig for my stuff (still kind of getting off the ground, here with the art). I have some experience with GTAW from a shop I worked in a few years ago...seemed to pick it up pretty quick on a Miller Syncro (I think) we had there at the time.

I would like to have up to 1/4"+ stock welding capacity as I also dabble in making my own shop equipment, tables, brackets, heavier sculpture, auto repair, etc. I recognize the value of pre-heat for thicker stuff to push the envelope, so really 185-225 amps would be quite sufficient I would say. At this time I am not in the market for a water cooler set-up.

I am also looking for a plasma cutter with pilot arc that would handle 1/8" plate with some speed, 1/4" material with ease, 1/2" at slow speed, and 3/4" severance (very rarely) without TOO much struggle. 110volt option would be spectacular in case I needed to take an air tank along for a quick cut on some scrap outside or at a buddies house as well (obviously on thinner stuff).

I have a 220V 20 amp circuit, and I believe a 220V 30 amp circuit available in my shop currently (obviously some 110v outlets also).

From what Ive gathered, Im leaning toward a 200DX with upgraded torch (if there is substantial benefit to a different torch than stock) and upgraded pedal (if the upgraded pedal yields a substantial increase in control or 'feel'). Im also considering the 185 microtig, but I think the pedal only offers low-full throttle? And also, I believe I would quickly wish for some more of the control features offered by the DX. However, if any here could specifically speak to which machine offers the best low-amp control, that would be very beneficial as well.

Im thinking of either the Super Cut 50D with HF pilot arc, or the Power Plasma 50. For the difference between $650 and $800, can someone break down for me advantages/disadvantages offered by these two units?

While these machines wont be in an 'industrial' environment where they see everyday use, I fully expect them to occaisionally be called upon to do a little heavy lifting and want full featured units.

Lastly, thanks so much for the forums and for taking the time to 'help a brother out'. Any and all guidance/advice is greatly appreciated.
