Continuous-path arc welding robot
Optimize your production line with high-speed, precision arc welding using our advanced hollow-shaft robotic arm, designed for seamless integration and efficient space utilization.

Performs Precision Welding and Flexible Automation
The KR CYBERTECH nano ARC from KUKA AG exemplifies precision in arc welding and flexible automation. Designed for continuous-path operations, it excels in producing automotive components like car body panels and electronics circuit boards. With load capacities of 6-8 kg and reach options up to 1843 mm, these hollow-shaft robots offer repeatability of 0.04 mm, ensuring exceptional accuracy.
Engineered for versatile integration within your production line, the robots’ compact design allows for any installation—floor, wall, or ceiling—adapting to your spatial constraints. Enhanced by KUKA’s latest controller technology, the robot provides adaptable performance through digital Motion Modes, optimizing precision and speed based on your needs. The long service life, coupled with maintenance-free axes 4-6, ensures reduced total cost of ownership (TCO).
Ideal for automotive, electronics, and metal industries, the KR CYBERTECH nano ARC supports operations like welding, cutting, applying, and machine loading. Its flexibility and energy efficiency make it a valuable addition to processing departments aiming for cost-effective automation without sacrificing performance.
