KOIKE LD-R Series is a small positioner excellent for general use. The LD-60R, LD-150R, LD-300R has a wider range of rotation speed with the dedicated controller LDR-B and DC motor. Futhermore, with the thorough noise-cancellation, any welding method is possible(High frequency TIG).
LD-600R uses table rotation and electronic inclined shaft through alternating current electric motor and inverter control. In addition, table can be rotated right or left without switching operation by using the 2-pedal foot switch.


  • An extremely wide range of rotation speed from low to high.
  • Thorough noise cancellation and also compatible with high-frequency TIG
  • Excellent grounding power collection even when brushless
  • LD-600R uses electric model on a table inclined shift.
  • Technical Specifications
