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.

FEATURES 

AWS ER70S-6 solid welding wire is ideal for MIG welding on all grades of steel. Typical applications include repairs on mild and low alloy steel, sheet metal, pipe, tubing and root pass pipe.• High levels of manganese and silicon deoxidizers tolerate medium to heavy mill scale surfaces
• Highly deoxidized for welding over moderate to heavy mill scale
• Stronger welds on oily or rusty steel
• Single or multi-pass

• All-position
