 HWASHI Automatic Relay Pin and Frame Assembly Welding Machine


  •       Main BodyAdopt the vertical stress main body. The machine is equipped with slide guide to provide stress supporting point and working platform for other actions.
  •       Pressurized Mechanism: Adopt double-layer of cylinder as the pressurized source which is control by good quality of imported electromagnetic valve and coordinated with precision-machined linear slide guide to pressure the electrode tip.
  •       Power Source: Adopt medium frequency inverter welding source. Duty cycle rate reaches 50%. The three-phase power supply is under rectifying through a special inverter and converted to1000Hz AC voltage and then be transmitted to a medium frequency transformer to be rectified so as to provide DC welding current.
  •       Welding Control System: Adopt the self-developed advanced microcomputer quick response touch controller, all-digital control, simple and clear operational interface.
  •       Main Engine Control System: Adopt the touch screen of Japan Panasonic as the human-machine interface, Chinese-English input.
