NACHI Robot Full Series

SC400LC: 6-axis, load 400kg, radius 3756mm, used for handling large glass substrates, cleanliness level meets ISO 14644-1.

Welding robot: SRA series

The SRA series is NACHI's advanced spot welding and arc welding robot, which significantly reduces cycle time with hollow arm structure, ultra-high speed, and vibration suppression technology.

8.1 SRA-H series (built-in cable spot welding)

SRA100HS/SRA100HB/SRA100H: Load 100kg, radius 1634-2044mm.

SRA133H/SRA133HL: Load 133kg, radius 2654-2951mm.

The welding gun cable is completely embedded in the hollow arm, improving cable reliability and increasing operation rate; A simpler appearance facilitates direct installation on assembly lines, improving the accuracy of offline programming.

8.2 SRA series (ultra high speed spot welding)

SRA100/SRA133/SRA166/SRA210/SRA240/SRA250: Load 100-250kg, radius 1634-2951mm.

Compared to existing models, the beat time has been reduced by 30%. Achieved through three major improvements: lightweighting, high rigidity, and high-speed control.

Compact design allows for high-density installation layout and easy maintenance (regular inspections and parts replacement are easier).

Reduce power consumption by 15% and minimize environmental impact.

Provide hollow arm version and bracket installation version (166kg/210kg).

8.3 Seam welding function

NACHI is the only company in the world that has successfully installed seam welding machines on robots. Seam welding is used for components that require airtight joints (such as car fuel tanks), where two roller electrodes rotate and are energized on the surface of the material to form a continuous weld seam. The robot seam welding kit can achieve high-speed and consistent seam welding on three-dimensional surfaces, and is equipped with various application functions such as electrode grinding and electrode wear compensation.

8.4 Other welding models

SRA166HT/SRA210HT/SRA210V, etc. are available in extended arm and high torque versions, with a load of 166-210kg and a radius of up to 3087mm, meeting special requirements such as welding inside the vehicle body.
