KUKA KR8 R2100-2 arc HW
Robot details
The KUKA KR 8 R2100‑2 ARC HW is a 6‑axis industrial robot specifically engineered for arc welding applications, combining extra‑long reach, high path accuracy, and welding‑optimized mechanical design for demanding industrial welding environments.
With a payload of 8 kg and an extended reach of 2,100 mm, the KR 8 R2100‑2 ARC HW is ideal for MIG, MAG, and TIG welding of large and complex components. The ARC HW configuration is designed for harsh welding conditions, featuring a reinforced wrist, protected internal cabling, and stable motion behavior to ensure consistent weld quality over long continuous seams.
The robot is powered by the KUKA KR C5 controller, KUKA’s latest‑generation control platform, delivering high‑performance motion control, advanced welding integration, and modern digital connectivity for automated welding cells.
Arc Welding Motion Concept and Performance
The KR 8 R2100‑2 ARC HW is optimized for smooth and precise continuous path motion, which is critical for high‑quality arc welding and process stability.
Key motion characteristics include:
- High path accuracy for uniform weld seams
- Smooth TCP motion for stable arc behavior
- Optimized wrist kinematics for precise torch orientation
- Reduced vibration during long welding trajectories
- Reliable performance in continuous welding duty cycles
The extra‑long reach of 2,100 mm allows the robot to cover very large welding fixtures without frequent repositioning or additional external axes, improving productivity and cell efficiency.
Controller & Software – KUKA KR C5
The KUKA KR C5 controller is KUKA’s most advanced industrial robot controller, designed to support high‑performance robotic arc welding applications.
Controller Highlights:
- High‑performance motion and path control
