KYA Fasteners' ER70S-6 Copper-Coated Welding Wire is designed for superior performance in MIG welding applications. Made from carbon steel and low-alloy steel, this wire offers excellent arc stability, stable feeding, and minimal spatter for clean, high-quality welds. Available in diameters from 0.8mm to 1.6mm and spools of 5kg, 15kg, or 20kg, it meets ER70S-6/ER50-6 standards. With high tensile strength (545 MPa), excellent low-temperature impact resistance, and superior crack resistance, it produces thin, easy-to-remove slag and beautiful weld seams. Ideal for all-position welding, it’s perfect for steel structures, bridges, and pressure vessels.
