This process is most beneficial for job-site welding, where you can use a self-shielded, flux-cored wire. No external shielding gas is required, and a majority the wires run in direct-current electrode negative, meaning most of the heat is generated in the filler metal wire and not the base material.

GLOSSARY OF WELDING TERMS Arc [Arc Length] - The physical gap between the end of the electrode, and the point where the arc makes contact with the base metal. Brazing - A group of welding processes in which a groove, fillet, lap, or flange joint is bonded by using a non-ferrous filler metal having a melting point above 427 C (800 F), but below that of the base metals.

Flux-core arc welding (FCAW) is an automatic or semi-automatic electric arc welding process. In practice it is very similar to MIG welding, in which both use the filler wire as an electrode for the arc. Some of the same equipment can even be used for both MIG and
7 Types of Welding Processes | The Welding Pro
During the welding, gases such as helium or argon (inert gases) are streamed to protect the electrode, the base metal, the weld pool, and the arc from interacting with the air in the surrounding. To produce the desired weld parameters such as wire feed speed, arc current and voltage, temperatures during preheating, the density of the current, and the rate of electrode travel should be considered.

What is Arc Welding? - Definition and Process Types - TWI
Arc welding is a type of welding process using an electric arc to create heat to melt and join metals. A power supply creates an electric arc between a consumable or non-consumable electrode and the base material using either direct (DC) or alternating (AC) currents.

In these welding processes, the length of the arc is kept constant because any variation in the length between the base material and the wire is immediately corrected by a huge current change. This means that if the distance between the base material and the wire is too short, the current will quickly increase, which increases the heat thus restoring it to its original separation distance.
