Robotic Welding Arms

OTC Daihen’s robotic welding arms are used for any CO2, MAG, MIG, TIG, and air plasma cutting application. All robots are Windows NT-based and operate on a CAN bus interface, which provides the highest degree of control and data monitoring possible. We also offer a full line of welding equipment for many different applications.

a2-b4 rototic welding arm

Almega AII-B4 Robotic Welding Arm

The AII-B4 robotic welding arms are the newest in robotic innovations. Sporting a unique design with a through-arm coaxial cable, this robot is highly versatile at welding in confined spaces or complicated fixtures. The coaxial cable of the AII-B4 also helps improve wire feeding, which helps improve overall weld quality.

  • Faster Speed – 20% faster than AX model
  • Through-arm coaxial cable
  • Quick, easy maintenance design
  • 4kg







a2-b4l rototic welding arm

Almega AII-B4L

The AII-B4L robotic welding arms represents the newest in robotic innovations. Sporting a unique design with a through-arm coaxial cable, this robot is highly versatile at welding in confined spaces or complicated fixtures, and has a longer total reach than the AII-B4. The coaxial cable of the AII-B4L also helps improve wire feeding, which helps improve overall weld quality.

  • Cable Built In – Dedicated for arc welding
  • Designed for Welding – Cable management standard
  • 4kg payload







a2-v6 rototic welding arm

Almega AII-V6

The AII-V6 is OTC DAIHEN’s newest standard arc welding robot arms. The AII-V6, like its predecessor AX-V6, supports most welding applications and is one of our most popular products

  • Versatile – GMAW, TIG, and Plasma Cut
  • Faster Speed – 40% faster than AX models
  • Dedicated Design – Best fit with Daihen welding machines
  • 6kg Payload






a2-v6l rototic welding arm

Almega AII-V6L

The AII-V6L shares many of the same features as the AII-V6 arc welding robot, and additionally features a longer arm for increased reach and is ideal for working with large fixtures. And like the other AII Series robots, the AII-V6L also features individual servo shock sensors on each AIIis to prevent damage to robot.

  • Versatile – GMAW, TIG, and Plasma Cut
  • Faster Speed – 40% faster than AX models
  • Long Reach – 2006mm/79 inches
  • 6kg Payload
