AII-V20 Arc Welding Robot from OTC DAIHEN, Inc.

The AII-V20 is largest dedicated arc welding robot, with a maximum payload of up to 20kg (44.1 lbs.). This unique trait allows the AII-V20 to be used in both arc welding and material handling applications.

The AII series robots are powered by the new AX21 controller, which features improved resistance to heat and dust, improved reliability in global environments, improved reliability and maintainability, increased sampling frequency for higher detection accuracy, and more.


  • Structure Vertical articulated type
  • Number of Axes 6
  • Max. Payload Capacity 20 kg (44.1 lb.)
  • Positional Repeatability ± 0.07 mm (± 0.003 in)
  • Drive System AC Servo Motor
  • Drive Capacity 5600 W
