Weldcote Metals ER70S‑6 is a copper‑coated carbon‑steel MIG wire formulated with higher levels of manganese and silicon, giving it excellent deoxidizing properties. This allows the wire to produce clean, strong welds even on steel with rust, scale, or light oil contamination. It is widely used for butt and fillet welding on sheet metal, plate, and structural steel across a variety of thicknesses. The .030" diameter offers smooth feedability and precise control, while the 11‑lb spool fits most MIG welding machines used in fabrication shops, automotive repair, and general manufacturing.
