Tigmate is a good unit, and so is the econotig , which is the miller equivilant.
There are a few things that you going to want in the machine, miller, hobart, lincoln, esab, or whatever...
Make sure its an AC/DC machine. Even if you just plan on doing mild steel only, there will be a time when you want to try aluminum, and nothing will piss you off more than not being able to. Ive been thare, and it sucks.
If you can afford it, get something wtih HF start. Scratch starting or lift starting is kinda hard to pick up for some people, and if you dont get the hang of it right away, you may get discouraged and give up. HF pretty much takes the guessing out of starting your weld.
Most TIG units you will be looking at, will come with a foot pedal for amperage adjustment. Some offer a "fingertip" control for the amperage, the tigmate is one of them. My suggesgion is to try each one out and see what you like better. Ive only used a regular pedal in the past, but i tried a friends fingertip control and i was very suprised on how nice you could manuver your body while welding, without having to stay confined to the pedal on the floor. If you plan on doing alot of welding on a bench, go with the pedal probably. IF you plan on doing alot of in vehicle welding, or on your back or any other hard to imagine position, try out the fingertip controls and see if you like it.
General rule of thumb for tig welding, is 1 amp for every .001 you wnat to weld. So, by this rule, a 250amp machine will weld .250 plate steel comfortable. They can do more, obviously, but thats a good place to start.
In my opinion, if your looking to hobby weld, not in a light production type situation, you have a few good options:
Miller Econotig 150
Miller Syncrowave 200
Hobart Tigmate 150
Lincoln Precision Tig 175
All those machines are between 1300 and 2000. All of them do AC/DC welding, and all of them have optional amperage control systems, and all of them have air cooled torches standard, which is all you should need. My personal choice out of them is the Syncrowave 200, with the running gear.
