The VBZ is a feeder for the fully automatic feeding of welding elements into automatic stud welding heads and automatic stud welding guns. With the VBZ welding elements with flange can be fed fast, safe and easy, the modification for special welding elements (e.g. insulation nails) is possible on inquiry. It distinguishes itself through very easy operation as well as fast and easy retooling to different stud diameters.
