How to Weld - MIG Welding : 11 Steps (with Pictures) - …
MIG welding uses an arc of electricity to create a short circuit between a continuously fed anode (+ the wire-fed welding gun) and a hode ( - the metal being welded). The heat produced by the short circuit, along with a non-reactive (hence inert) gas locally melts the metal and allows them to mix together.

welding - Can I use flux core wire with MIG shield gas …
Dual shield wire is a different animal than regular flux core wire. You can use gas with regular flux core, but it is a total waste of gas. The flux in dual shield wire doesn''t shield the weld, it causes better deposition rates and weld characteristics in the weld.

When it comes to choosing a shielding gasses and filler wire it is best to ask you welding supply store. They are the ones who know what gasses work best with the base metal and filler wire chosen. Some electrodes have specific shielding gas needs and the manufactures are the ones that keep the welding supply stores up to date on what coinations work best.
The Causes of GMAW Flaws | Bernard
Extend the welding wire no more than 1/2 inch beyond the nozzle and make certain that the base metal is clean prior to welding. Slowing travel speed to gain greater shielding gas coverage can also coat porosity, as can keeping the nozzle within 1/4- to 1/2-inch of the base metal during welding.

GAS METAL ARC WELDING (GMAW) – MIG Welding skill level: low to moderate A process used with a wire-fed welding machine. Metals are joined by heating them with an arc, which is between the continuously fed filler metal electrode (solid wire) and the
How to Buy a Welder | How to articles
Mig Welding (Wire feed / GMAW) - Mig systems use a wire electrode fed through a gun to make a weld puddle. Most systems have the option of using flux-cored wire or a shielding gas. Mig welding is the easiest type of welding to learn; the average homeowner can buy a mig welder at the hardware store, take it home and be making decent welds within a few hours of practice.
Gas metal arc welding - Wikipedia
Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join.

Fluxcore with gas ? - Weld Talk Message Boards
The wire is designed to burn some of the flux to generate the shield for the molten weld puddle, adding shielding gas changes the chemistry of the weld and can cause weld bead cracking. The manufactures also specify a min and max voltage range for these wires which is usually a spread of 3-4 volts running with a higher voltage can cause cracking as well.
Do i need flux core welding wire in a MIG welder …

Getting to Know Flux-cored Wires - The FABRIOR
While the wire may operate with either shielding gas, altering the gas is considered an essential variable change that can require new welding procedures and testing before use. Wires operating with 100 percent CO2 offer more weld penetration, but also tend to create more spatter, whereas wires for mixed gases have reduced spatter and smoke, along with a smoother bead appearance.
