You do not use gas with flux core. Use gas with plain wire. The best way to improve welds is to weld, weld, and weld some more.

oh I know how to weld, I just never welded with flux core wire. So I guess that wire that came with my new welder is worthless to me. Gotta buy new spool of regular wire

The flux core can weld decently........it spatters more and more grinding is needed afterwords.

gas flux core

yes you can use gas with gasless flux core , in the old days industrial welders us to do thsi until flux core became better, but in general it is kind of over kill, but on the other hand in the industrial market there are flux core wires that requires gas (co2 flux core) used often in heavy metal fabrication.

but i general and use hot rodders alway think we can invent something new,

its boring but follow manufactures reccomdations but it will work in this case

being a good welder require practice and experience, and being agble to handle to ever changing conditions for each weld.

but for most auto hoby work i would reccommned bare mig wire with gas, and then maybe regular stick welding for frame and suspensions

You will only be wasting gas to use it with gas-less wire There are several different kinds of "duel shield" wire which is a flux cored wire that REQUIRES gas but these wires are in no way the same as "inner shield" or gas-less wire. You will not see any improvement at all with the gas on a gas-less wire and in fact you probably will not be able to see any difference in the weld at all. On a gas-less wire the flux contained in the core creates a gas shield that protects the weld from atmospheric gases and this same shield would also prevent the gas from a tank from reaching the weld thus it would have no effect on the weld.
