As said before, start with MIG and make sure you get a welder that uses, or is upgradable to use, gas. I've used both Lincoln and Miller and both are the same as far as I'm concerned. I would recommend bigger over smaller though. You can always turn a big welder down but once you get the hang of welding, you'll out grow a small welder real quick.

One thing that hasn't been mentioned is protective gear. Don't cheap out here as better gear makes a world of difference. Definitely go with an auto-darkening helmet versus a regular lensed one. It makes things so much easier it isn't even funny. I use an ArcOne Python Fighting Tiger 5000v and I love it. Comfortable, good viewing area, adjustable darkness and sensitivity, inexpensive replacement lenses, and it doesn't hurt that it looks cool. Also, make sure to get a good pair of insulated welding gloves, your hands will thank you. I use Tillman's. For the protective gear, take a look at Weldersource.com, it's where I get all my gear and they have the best prices I've found anywhere, along with good service and free shipping.

HI,
I weld and have a small Miller MIG. I also volunteer at the USCG shop doing metal fab. The difference between little welders at their max and a 250 amp machine is great. It is hard to go back.
I suggest you invest a bit in yourself first. Find a junior college with a welding program and do a semester or two. They may have a special program to train users doing just what you want to do with a small machine.
Then, decide how into welding you want to go. Used professional machines are available. Check in with your local Miller sales shop for demos and returns.
Good luck, Roy

Great advice!
