A general purpose of welding wire with copper coated for long contact tip life is provides superior feeding and arc stavility design for fabrication of mild steel. Contains higher level of manganese and silicon than the other standard grades of MIG wire, provides superior feeding and arc stability design for fabrication of mild steel. Contains higher levels of manganese and silicon than the other standard grades of MIG wite, provide high deoxidizers to heavy mill scale surfaces that provide better wetting, yielding a flatter bead shape and the capability of faster travel speeds. Usually used with 75/25 (Argon/Co₂) shielding gas or higher contents of Argon, such as 90/10. Can also be used with 100% Co₂. Conforms to AWS A5.18 ER70S-6E.
