KYA Fasteners' ER70S-6 Copper Coated TIG Welding Wire is engineered for gas-shielded arc welding of mild and low carbon steel. Featuring a copper coating for enhanced feedability and corrosion resistance, this wire delivers stable arc performance, minimal spatter, and beautiful weld seams. With high tensile strength (558 MPa), low hydrogen content, and excellent crack resistance, it’s ideal for all-position welding in steel structures, shipbuilding, bridges, and pressure vessels. Available in diameters from 0.6mm to 1.6mm, it suits thin to thick plates in industries like construction and petrochemicals.
