1 mm Co2 Mig Welding Wire, Thickness: 1.2 mm

There are two primary types of MIG welding wire – flux-core and solid MIG welding wire. Flux-core wire is a metal electrode that contains a "flux compound" inside the electrode. When the wire melts and reacts with the welding arc, this forms a gas that protects the weld from oxygen, which can cause defects in the weld
