Standard 0.8mm Mild steel MIG Wire suitable for use with Argon Mix Shielding gas. This grade is the MIG Wire most commonly used by Fabricators and Welders working with Mild steel.

Copper coated double-deoxidised SG2 mild steel MIG wire for welding unalloyed and low-alloyed mild and medium tensile steels, for impact toughness down to -30C. Manufactured with a high-quality copper (0.08%) finish for improved feeding. Precision layer wound.  A 15kg MIG wire spool is suitable for the larger industrial MIGs such as the larger MIG welders in the Jasic and Cebora ranges and all Oxford and TecArc (non-inverter) MIGs.

G3Si1 MIG wire is suitable for use in general fabrication, steel construction, automotive, machinery production, ship building, boiler tanks, pipe parts, thin walled steels, and sheet welding. Comprises manganese (1.45%) and silicon (0.85%) to provide great welding properties, and designed with smooth feedability in mind for the best results possible. Able to perform effectively in all major welding positions.


Packed onto a steel basket spool. Unlike the classic plastic spool, this kind of Mild steel spool is sturdier in transit and is better for the environment as it can be recycled.
