I just installed a cage in my 68 dart, I tacked it in with a 110 amp lincoln mig welder. then I welded it solid with a 200 amp mig welder. The instuctions with my cage said use atleast a 130 amp mig welder.
What size wire are you running? I have done tons of sheetmetal with a Lincoln 115v welder with the 4-taps.daneddy said:I bought a Lincoln 115 volt unit wire feed MIG with four taps for current. It does marvelous on anything thicker than .061 and up to .25 but when trying to weld to .061 sheet metal (body work) it sucks. The lowest tap setting is almost not enough current and the second tap is too much. So you're stuck either blowing holes in the metal or not getting enough penetration. If I had it to do over I'd buy a 220 machine with infantely adjustable current so I could adjust to thinner gage metals.
I have had some sucess by backing my thinner metal welds with a plate of copper which helps even out the heat and prevent blow throughs. I'm not a professional at welding but I'm learning the tricks. My welds are strong but not as pretty as some but betting better as time goes on.

Sheesh, sounds like you got a garage full of tools for 300 bucks, good deal. If you plan on doing a lot of sheet metal you may want to switch to the .025-.025 wire. It works well on sheetmetal.mopowers said:I ended up buying a 135 Pro-MIG. I know it is kind of small, but it was almost new and came with a speedglas auto darkening helmet, 96 CF full Cylinder, welding gloves, new gas powered mower, milwakee chopsaw, 2 porter cable routers, a 12 v corless drill, a creeper, 2 palm sanders, and 2 angle grinders. All of this was 300 dollars. I found them on craigs list about 1.5 hours from my house. The guy was going through a divorce and needed money asap. The welder as been working really well on filling the holes on the body panels from the trim. Just have to turn the wire speed up so it didn't blow through. Also use a bigger stick out (I think thats the term). And I've been using .030 w/ C25 gas.
For a beginner or DIY hotrodder, a MIG (Metal Inert Gas) welder is an excellent choice. MIG welding is a relatively simple process that produces clean and strong welds, making it ideal for roll bar, subframe connectors, and body panel work.I bought a Lincoln 115 volt unit wire feed MIG with four taps for current.
