Any MIG welder will work. Just turn wire speed all the way down, and power all the way up.
I've used a Hobart Handler 140 Mig welder with .23 wire for floor, rockers, other thin sheet metal, etc on my car with great success. It runs off standard 115V household current and has enough range to do almost any job on a car, certainly sheet metal. I've butt welded 22 gauge to 18 gauge patches with no problem....as long as you have good fitment with your patches and get a feel for the settings. You can go cheaper (but not really by too much if your going to be running gas....which you should be) but imo you get what you pay for. Developing OCD on cutting and fitting patches will be a huge help
Miller 180 here, but it's 220V, so I had to run a new circuit out to the garage. For thin sheetmetal patches, run hot, but in short tacks. You also need enough wire speed to the point where you don't burn back. It was tricky for me at first, but with enough helmet-time, I got fairly decent at it.
I want a welder also! I was also looking at the Hobart Handler 140. Seems like a pretty decent rig. It's nice because you can bring it anywhere basically. I have welded before and took a class a few years ago. I have not done it since and it's to bad because it is a lot of fun I think.
i have been reading your build thread a looking at pics over and over that's what maid me wanna work on my car and weld the rust in floor and wheel wells i am going to practice with some junk metal first i have never welded b4 in my life. i going to get a welder tmro and helmet ect and tearing car down so i see if their is more rest then i have already found. and will post pics.

i have an electric 125 lincoln. cheap and works great specailly to make reinforced pans
I used to use a Lincoln PowerMIG 255 with an argon tank at my father's work, but then they moved their shop location and management got strict on after-hours use of equipment, so now I'm using a Proline MIG-100. Used to be 6% duty cycle, but I installed a 400CFM 12" fan on the back of it and now it will trip a dedicated 20-amp breaker before the transformer overheats.
We need a series like this state-side. I'm in if there is one, or will be one. VW Cup 2013, anyone?
