The steel wire is fully immersed in one or several pairs of electrodes in the cleaning solution. Under the action of current, the dirt on the steel wire surface is quickly removed. Through the electrolytic coating tank, a film is rapidly formed on the steel wire surface under the action of a pair of electrodes. The conductive film can meet the performance requirements of copper free welding wire after electrostatic oiling.

 

The electrode is powered by a rectifier with a voltage of 30-50V and a current of 50-150A
