I splurged and bought a Lincoln Mig with the CO2 gar bottle and controls. This to fix sheet metal rust on my Metro
I am a decent stick welder. All I got from the Mig was splatter, really looked like crap. I left it in a corner. A trusted friend told me to try flux wire. It worked 100% better! Yes, it left slag to chip off but the weld was decent with penetration. Why? The machine wasn't trying to melt as much wire. YMMV -- Peter T.
