Buy discount MIG welders from Miller Electric and Hobart. The Metal Inert Gas (MIG) welding process uses a continuous wire electrode, or spool wire, along with shielding gas to create a weld. The shielding gas protects the weld from oxygen and moisture contamination. Argon, carbon dioxide or argon mixed gases are the most commonly used shielding gases.
MIG welding is most often used for automotive work and general metal fabrication. MIG welding is very economical and user-friendly. MIG welders can also be used for Flux-Cored Arc Welding (FCAW). Flux-cored welding wires utilize an internal flux to shield the weld from outside contamination. Self-shielded flux-cored welding wires require no gas cylinder.
