Product Description
A Heavy-Duty Copper Butt Welder is an industrial-grade resistance welding machine designed to perform precision butt welding of copper conductors such as wires, rods, flats, and busbars. It utilizes high electrical current and controlled mechanical pressure to create a seamless, solid joint between two copper ends. These machines are widely used in electrical, automotive, cable manufacturing, and transformer industries, where high conductivity and mechanical strength are critical.
Depending on application size and automation level, machines may come in manual, pneumatic, hydraulic, or servo-operated formats, with optional flash butt welding, annealing, or PLC automation.
