We have used our Miller Dynasty 165 for just about everything and IMO it is a great machine to start with. We will be looking to upgrade to something with a liquid cooled torch at some point. But for the money this has been an excellent welder. PS you can find them cheaper searching the net.

Both our Lincoln and HPT are liquid cooled.

I've been teaching myself to tig with an Everlast 225LX. I really like it and find it to be easy set up and understand as well as a very capable machine.

Jody @ Welding Tips and Tricks gave the Everlast machines a good workout comparing them to other better known tigs and he thought them just as capable. Good enough for me to but one.

Alphatig - same as an Everlast. If I had to chose between the two, I'd go with the Everlast. They at least have some support in North America. The Canadian rep is the guy who goes to China and specs out the units, the changes and runs the tests. So at least there are some North American "boots on the ground". The others are probably just repaints. Everlast has a good website with forums that are worth checking out.

FWIW I do not own an Everlast - but I came close!

I really like my Lincoln 185 precision tig. I also have an older Esab DTU300 tig unit that I bought cheap. Built my own cooler for it and used it on 2 or 3 customer jobs and it quit working. Go figure! still need to get it repaired. Personally I think the newer smaller machines are easier to use. They seem to be easier to set up and also have the auto balance and pulser that really helps in the AC mode. Beep
