CWL50N-6 is environmental protection solid wire with Tensile strength 490Mpa , this welding wire surface is treated by special process, save copper plated process, reduce environmental pollution; The welder is free from the damage of copper smoke during welding, and better protects the health of users.

The production process of Copper-free solid welding wire is designed with the new technology. Its following steps : Wire release frame→Abrasive band polishing→ rough pulling→Fine pulling→Lubricating antirust oil→Welding wire post-treatment→wrapping machine winding. The welding wire is completely solved the acid-free derusting and the post-treatment lubrication process of the welding wire, and the surface of the welding wire after the welding is uniform and smooth, and the wire feeding resistance is greatly reduced.
