Related products of the GBX-5(A) Cored Wire Machine: WX-4BF and WX-5BF dual-stream wire feeders. These dual-stream wire feeders are directly driven by stepless speed-regulating motors, equipped with electronic counting and digital display functions, and are provided with speed and length setting devices, as well as an electromechanically separated clamping mechanism with manual and pneumatic complementarity. They can realize dual-stream feeding of different types of wires at different speeds, lengths and times, and can also optionally perform single-stream feeding. With the advantages of complete functions, accurate counting, small size, stable transmission, and safe and reliable operation, they are ideal wire feeding equipment.
