  • Very high welding speed, e.g. For a 16-wire oval cage, one ring takes only 0.24s
  • Rings are locked while welding, ensures good perpendicularity between ring plane and cage axis
  • Gear rack transmission achieves high precision of ring space, ring space can be set in the program through the user-friendly interface
  • The cage is pulled by servo motor, no accumulated locating tolerance, ring space precision is 0.1mm, pulling speed is 0.4m/s
  • Function of bad weld detection and auto re-welding
  • Material selection, different welding parameters for mild steel, galvanized steel and stainless steel
  • Auto compensation gives enough space to insert the ring when the ring distance is short
  • Rails (standard 7500mm, up to 9000mm) and material shelf equipped and connected to the welding unit. The front end of the rail is adjustment-free. Good linearity can be achieved for wire cages
  • Positioning mould manufactured with wire-cutting process, it features high accuracy, good insulation and long life
  • Four air tanks, short air route inside the machine ensures quick response of the cylinder
  • 25mm front plate resulted from one-time machining, firmly secure that the welding cylinders are on the same plane and perpendicular to the axes, thus the linearity of the cage can be ensured
  • Equipped with powerful micro-computing unit
  • Time-sharing power-on transformer reduces the burden on local electricity grid
