Instead OF the traditional copper plating process, the coating process OF active substances eliminates the copper plating process in the production process, reduces energy consumption and environmental pollution. The use of active substance is not only have the effect of the conductive, lubrication, and significantly reduce the welding smoke and welding spatter, almost no copper ash, conductive mouth and stable contact resistance between the wire, wire feeding more stable smooth, under the condition of same current cladding increase, improve the welding efficiency, reduce production cost, stable electrical conductivity, good anti-rust performance. The product is characterized by energy saving, low carbon and environmental protection. It is more suitable for the application scenario of automatic welding long-distance wire transportation. With breakthrough and industry-leading new technology, new material and new process, it is an environmentally friendly product suitable for automatic and intelligent welding manufacturing.
