ER70S-6 is a premium copper-coated solid welding wire designed for MIG/MAG welding of mild and carbon steels. With higher deoxidizer content (manganese and silicon), it provides superior arc stability and weld bead appearance, especially when welding over mill scale or slightly rusted surfaces.

It is widely used in general fabrication, machinery manufacturing, automotive parts, pressure vessels, pipelines, and structural steel work, offering high deposition efficiency, low spatter, and excellent mechanical properties.
