Tig torch...

I like the foot pedal set up, one less thing to do with your hands so you can focus on the weld. Pretty intuitive anyway, the coordination isn't a big deal. Works the same as a gas pedal, and I'm sure you know how to work one of those. :D

All the TIG stuff I've had has been water cooled, so I don't know about the quality on the other stuff. My current set up is a Miller 320 AB/P with an external water cooler. Works great, the set up is a little more difficult than the modern stuff since its a '72, but once its set up it welds great. And no digital anything to break, all old solid state stuff.

I have talked with a friend that owned a fab shop. He did suggest I at least look into a water cooled setup. He told me that unless I was going to be pushing the machine to its duty cycle a very simple setup would work. I mentioned I have a chiller from my old aquarium and he said that would be more than enough....just need a small reservoir and a pump....

My machine is from 04 or so I believe. I used the machine at a class I was at, seemed to work well. A Miller rep was there and said that it is a hard to beat machine...not as easy to use as one of the newer ones but at the price they were asking it was a great deal....
