Nachi SRA100HS/SRA100HB Spot Welding Robots

Manufacturer: NACHI
Model: SRA100HS/SRA100HB

Features

Cable built into the hollow arm
Welding cables and hoses packed tightly inside arms with hollow construction.
Avoids interference with peripheral equipment through the displacement of cables.
Improved reliability and safety of cable performance through wrist operations
The embedded welding cables in the arm make the off-line programming easier.
Compact body
Minimized robot height so it can be used in multilevel arrangements
