Product catalog summary
Main Features
  • The CWM 100 uses capacitor discharge welding for segment connection, ensuring no distortion or annealing of the workpiece due to the rapid welding process.
  • It maintains consistent quality through constant force control and correlated current input.
  • The machine features automatic workpiece positioning with two linear axes and one rotation axis, and a manual clamping system.
  • An intuitive touch panel interface is provided for ease of use.
  • Compared to CO2 welding, it produces fewer welding fumes and spatters.
  • The machine offers short cycle times and high efficiency with low operating costs.
Options
  • Higher welding energy options up to 24,000 Ws.
  • Additional mandrel and clamping support, templates, and electrodes are available.
Functioning

Diamond segments are manually placed using a template. The machine automatically positions and clamps the segment between electrodes, applying a current pulse to achieve welding. This process is repeated for each segment.

Technical Data
  • Total electric power: 38 kVA, with a supply voltage of 3 x 400 V, 50/60 Hz.
  • Requires a 35 mm² equipotential bonding connection.
  • Total connected load: 3 x 53 A, with customer-provided fuses of 3 x 63 A.
  • Compressed air consumption is approximately 50 l/min at a minimum pressure of 6 bar.
  • A customer-provided suction system with a recommended air flow rate of 600 m³/h is needed.
  • Supports cup wheel diameters of 80 – 254 mm and a maximum workpiece height of 30 mm.
  • Maximum welding energy is 12,000 Ws, with an optional increase to 24,000 Ws.
  • Weldable surface area is approximately 350 mm², with an optional increase to 700 mm².
  • Maximum setting back force is 30 kN at 6 bar.
  • Manual segment positioning using a template, with a cycle time of approximately 5 seconds per segment.
  • Workpiece positioning includes X-axis stroke of 300 mm, Y-axis stroke of 400 mm, and C-axis rotation of 360°.
  • Manual workpiece clamping.
  • Machine dimensions are approximately 2,605 x 1,390 x 2,440 mm, with a weight of approximately 4,000 kg.
