ER70S-6 Mild Steel MIG Wire is a high quality, copper-coated, triple de-oxidised solid MIG welding wire supplied on 15kg, 5kg and 1Kg precision layer wound plastic spools. The wire contains higher levels of manganese and silicon than most standard grades of MIG wire to produce high-quality welds. The high silicon content increases the fluidity of the weld pool creating a smoother bead appearance and resulting in minimal post-weld grinding. The wire is engineered to provide porosity-free, x-ray quality welds with high tensile strength. ER70S-6 Solid MIG Wire requires a shielding gas such as CO² or Argon/CO² mixes.
