KOZA-KZH-CR625-2000 New-Gen Industrial Collaborative Welding Robot (25 kg)
KOZA-KZH-CR625-2000 is a KOZA KZH-CR series new-generation industrial collaborative welding robot: 6 axes, 25 kg payload, 2000 mm reach, ±0.05 mm repeatability and IP54 protection. It combines industrial speed and precision with collaborative safety and ease of use — high-speed mode for welding cycle times, collaborative mode for smarter safer operation — suited to arc welding, handling and flexible welding cells.
Key selling points
- Industrial collaborative welding: built for new-gen collaborative welding lines; integrates with torches, wire feeders and fixtures while keeping people safe.
- High-speed / cobot dual mode: high-speed mode matches industrial cycle times; collaborative mode runs at low power, smarter and safer.
- Collision protection: collision detection via motor current or feedback torque stops the robot quickly on external force.
- Long reach, high payload: 2000 mm reach and 25 kg payload for mid-to-large workpieces.
- IP54 protection: body and cabinet IP54 for dusty welding environments.
