WX-5BF variable frequency wire feeder is directly driven by a stepless speed regulation motor, equipped with electronic counting, digital display, speed and length setting devices, electromechanical separation, and manual-pneumatic complementary clamping mechanism. It can realize dual-stream feeding of different types of wires at different speeds, lengths and times, and can also select single-stream feeding arbitrarily. It has the advantages of complete functions, accurate counting, small size, stable transmission, safe and reliable operation, and is an ideal wire feeding equipment.
