Spot welding robot with built in cables

Welding robots are the central element of automobile production, especially in auto body welding lines. The performance, functionality, and reliability of the Nachi lineup of spot welding robots are supporting the world of manufacturing.


SRA H Series

The next generation of hollow arm construction spot welding robots. Cables for welding gun are fully enclosed to increase cable reliability and improve rate of operation. Provides a cleaner profile for installing directly in the assembly line and improves operational accuracy of offline programming, including welding cables.

Features and Benefits

  • SRA H Advanced Hollow Arm Design
    • Hollow arm design neatly packages all pneumatic, power, and servomotor cables.
    • Eliminates the need for external dress packages
    • Permits extremely accurate offline programming and simulation studies
    • Internal dress eliminates cable snags with peripheral equipment
    • Improved cable life minimizes maintenance requirements
  • Improved Productivity
    • High speed gun motor control for fast open / close
    • High acceleration SRA H robot for quickest movement between welds – SRA H robots are the world’s fastest in their payload class
  • Extensive product line
    • SRA H comes in various payloads from 100kg to 220kg
    • Standard floor mount models, invert mount model, long reach models over 3 meters.New hollow arm series for internal dress of spot welding utilities provides extra protection and minimized stress for utility lines (cooling water, weld power, signals, servo gun cables)
