Just trying to learn all that I can here. Thanks. I hope your typing fingers are ok. And to pay you back for your help, There is one benefit, I don't know if it has been discussed on this forum, and that is using flux core with shielding gas, for working outside in the breeze.

Flux Core would work fine for weld-in style SFC's. You can make high quality welds in all positions, the puddle is easy to control, and it has good penetration. Little pre cleaning is required with fluxe core, so you could weld in pieces that were just cut without cleaning off any mill scale. Flux core is more of a dirty type of welding with all the spatter and slag. It's used more for heavty duty welding like construction or farm equipment repair, thats why you dont see it in auto shops very much.
I would much rather weld the SFC's with MIG if i was in your postion, but FCAW would work just fine.
hope this helps

you cant run both flux and a shielding gas because you must change the polarities of the current, ie: negative and positive.

It does improve the weld quality of flux-cored wire, but it's still not as nice (in my opinion) as solid wire.

I have never been able to weld sheet metal with flux cored
and barely with MIG. MIG is going to have less penetration
which you want for the places where you might weld SFC
tabs to the floor pan etc. Flux cored does not have the
heat removal of the shielding gas so you have to be more
careful not to blow through. I'd practice a lot on similar
gauge materials, before putting it to my car.
If you have a lot of spatter try putting a few layers of
masking tape.

I dont agree with your last statement. Using flux core give yout the advantage to weld thicker metal than shielded gas for instant 1/4 inch metal. with a standard 220 welder you have to use flux core to weld that thick of a metal together and make multipal passes. If you get too much splatter then your welding too hot

i am a machinest and in no way a welder, i work in a welding/machine shop we make hydraulic winches for the new bedford fishing industry and i have beed told that flux core wire is stronger than regular mig wire. we use flux core wire on a lot of stuff, mostly stuff that is machined after, so is it stronger or not. also what i get out of this is i should use regular mig wire, when i have it done i have acess to mig, tig,arc , i plan on usin anti spatter on it and do i have to remove any of the rug because of the heat, sorry to ramble on, and thanks in advance.

True...i forgot we were still talking about ferrous metals...
jimmy blue is right...get some scrap metal to practice on if you want to weld the car yourself...
