Characteristics: This production of non copper coated welding wire completely solves the copper pollution problems created in the process of production and using. By adopting special passivation technique on the surface of welding wire, the surface is bright and clean, rust resistance is strong. Wire feeding is stable, and the wire is suitable for long-time continuous welding.

Application: Non copper coated welding wire is widely used in coal mine machinery, engineering machinery, ships, bridges, pressure vessels, construction facilities and other steel structure welding and welding of low alloy steel,.

Wire Size: 0.8mm,  1.0mm,  1.2mm,  1.6mm.
