Arcos Industries ER70S-6 MIG Solid Welding Wire

Arcos Industries ER70S-6 MIG Solid Welding Wire, 0.035 inch diameter, is a carbon steel filler designed for MIG welding. As an AWS ER70S-6 wire, it blends manganese and silicon in its chemistry to support a stable arc and deoxidation across carbon steel welds. Typical ER70S-6 chemistries include carbon 0.06–0.15%, manganese 1.40–1.85%, silicon 0.80–1.15%, and sulfur up to 0.035%, giving the deposit good fusion and tolerance for mildly dirty surfaces. The 0.035" size makes it a common choice for general fabrication and repairs on thin to mid-thickness carbon steel and is compatible with standard MIG equipment and drive systems. When used in gas metal arc welding, it is compatible with common shielding gas mixtures for carbon steel welding, delivering consistent bead shape, manageable spatter, and dependable ductility in the final weld. Applications typically include structural steel, metal fabrication, equipment repair, and fabrication of frames and components where carbon steel welds are required. This wire supports reliable performance in both shop environments and maintenance settings where a versatile, easy-to-wire filler is beneficial.
