High-speed copper plating of welding wire is brown brown liquid, which is used for non electrodeposition of high-speed copper plating film on iron to facilitate wire drawing process. It can make copper ions deposit orderly, make copper deposit compact, and have strong adhesion. At the same time, the complexing agent can also effectively complexe excessive iron ions in the tank solution, so that the tank solution remains stable. The deposition film is golden yellow and pink, which is loved by users. It can be used as immersion or continuous production line. The weight of copper film is 5-20g/m2
