Blake...I bought a Lincoln mig, I love it. Not a real big one, used mainly for sheetmetal but I can weld up to 1/4". I did quite a bit of arc welding but not much mig on sheet metal. First I tried fluxcore wire on sheet metal, never again. Then I used solid wire, .030, with CO2, OK. Then I swithed to .025 solid wire with 75% argon, 25% CO2, what a difference. Much cleaner welds, better penetration, less spatter.
