Any welders on the board?

What is the down side of flux core, other than the clean up needed afterwards ? I'm not a welder but the only welding i've ever done was with a flux core wire. Seems easier for a beginner like me.Also it's just easier to carry around w/o that bottle. I just bought a Lincoln wire welder (flux core) that I can get the conversion to gas for.It's another $100.

Flux core wire actually creates a hotter arc and the flux sprays off the end of the wire. Both of these conspire to blowing holes in sheet metal. As others have stated 0.023 wire and sheilding gas is the way to go. Also, I agree the 75% co2/25% argon is the way to go but 95% co2/5% argon will get the job done for a lot less money.
