The invention relates to the technical field of equipment for welding wire production, in particular to a high-speed copper plating production line. The high-speed copper plating production line comprises a pay-off machine; finish broaching machines, a spiral degreasing machine, a high-speed copper plating device, a washing tank, a traction machine, a tensioner, a safe wire arranging pipe and a take-up machine are arranged behind the pay-off machine and used for allowing a welding wire to sequentially penetrate through; and the front end of the safe wire arranging pipe is horizontally and rotatably connected with the rear end of the tensioner, an orifice of the safe wire arranging pipe corresponds to a wire outlet of the tensioner, and the rear end of the safe wire arranging pipe is connected with a wire arranging device of the take-up machine. The high-speed copper plating production line is reasonable in structure, scientific in design and high in copper plating efficiency, welding wires can be conveniently and safely coiled, the occupied area of the whole production line is greatly reduced, the factory space is saved, and the production line is more convenient and fast to use.
