  • Input voltage: 380V(3-phase) or customized
  • Power frequency: 50/60Hz
  • Designed max. capacity of transformer: 40KVA
  • Instant power during welding: 18KVA(for 4mm wire)
  • Instant power during forming: 3KVA
  • Wire thickness: 2-6mm
  • Max ring diameter: 350mm
  • Min ring diameter: 90mm
  • Ring perimeter tolerance: 0.5mm
  • Cooling: Natural cooling
  • Air flow required: 250L/min
  • Air pressure: 0.6-0.8MPa
  • Throughput: about 1560pcs/hr(for ring diameter 150mm)
  • Weight: 1300KGS


  • High precision: intelligent "S" shape speed curve, the encoder and the servo motor form a closed-loop wire feeding control system, secure a diameter tolerance less than 0.13mm, eventually solve the ring precision issues inherent in the traditional mechanical or hydraulic ring making machines.
  • Advanced and reliable wire feeding: the feeding unit includes a high-end servo motor and a planetary reducer, works on the basis of "dual-drive".
  • Automatic ring making: sizes can be adjusted automatically, worker attendance is not required during machine running.
  • Compatible welding: capable of welding low, medium and high carbon steel, spring steel, galvanized steel; if equipped with a TIG unit, it can also weld stainless steel and titanium rings.
  • Easy operation and maintenance: user-friendly interface on touch screen, easy to adjust, operate and diagnose the machine.
