Don't Discount Flux Core For Entry Users!
I don't want to start a huge debate on weld quality, etc. with this but don't discount flux core too much.
I work with a lot of high school kids that want to get into welding. Naturally, after running a few beads in the shop, they want to get their own set up.
However, getting a full mig setup can get pricey with a tank and regulator, not to mention the recurring cost of gas. I try to encourage a quality machine that has both flux core and mig capabilities.
They can then run thousands of feet of weld very cheaply with flux core while they are working on their technique. No, the welds are quite as pretty but the processes (and trial/error) are still the same.When they get better and have a little more money, they can always add gas.
