I have MIG welded for some time (mainly stainless) and have recently bought a new MIG/Flux wire feed welder for my garage. I have never used Flux-Core before and I'm wondering what the main differences are? Do you push or pull your pool? Is it a preference thing? Do you run it faster or slower? I assume you have to chip off slag as with Arc Welding?

Most people seem to say that when MIG-ing to push your pool but I've always enjoyed success Pulling it with my Gun more strait up and down. Any way how does this translate to Flux-Core?

Also most everything I have read states that Flux is for a bit thicker applications sighting that you can’t really weld Sheet Metal with it... What if you simply go a little colder and/or perhaps faster?? What is the thinnest gauge that you can weld with Flux-Core in the "real world? I have read no thinner than 20 gauge

I know lots of Questions but I have many. And the guy that said half the fun of getting set up and finding a "routine" that works for you is half the fun was right. Having a jump on it with a little help from some of the fine folks here cant hurt either though.
