Filter Cage Welding Machine - 6th generation


  • One machine can weld the whole cage, including top collar, cage body and bottom cap
  • Model: DLN-24-6
  • Cage wire quantity: 8/10/12/14/16/18/20/22/24
  • Ring space: can be set at any value
  • Cage outer diameter: 110-200mm
  • Rail length: standard 7m, up to 10m can be customized
  • Input voltage: 380V(2-phase) or customized
  • Power frequency: 50/60Hz
  • Designed max capacity of transformers: 160KVA
  • Instant power in sync mode: 36KVA
  • Instant power in async(time-sharing) mode: 18KVA
  • Transformers: 2sets
  • Air pressure: 0.6-0.8MPa
  • Required ir flow: 300L/min
  • Cooling method: natural cooling
  • Weight: about 1600KGS


  • Very high welding speed, e.g. for a 12-wire cage, one ring takes only 0.18s
  • Automatic cage pulling, ring space can be set in the program through the user-friendly interface.
  • The cage pulling carriage is equipped with bearings, runs on the rail with linear guides, it's smooth and precise
  • 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
  • Ring space precision is 0.1mm; cage pulling speed is 0.4m/s
  • Rails and material shelf equipped and connected to the machine. The front end of the rail is adjustment-free. Good linearity can be achieved for wire cages
  • Four air tanks, short air route inside the machine ensures quick response of the cylinders
  • 25mm thick 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
  • Stroke-adjustable cylinders increase welding speed, pre-pressing only takes 0.08s
  • Equipped with powerful micro-computing unit
  • Sync/Time-sharing mode can put two transformers work at the same time or one after another, secure good welding quality even when the power supply is not very sufficient
