# Nachi SRA210T

Hardware · `SRA210T` · verification: source checked

The Nachi SRA210T is a six-axis articulated robot of the SRA series, built for spot welding and material handling with a 210 kg payload and a 3106 mm reach. It is driven by AC servo motors and is paired with a Nachi FD controller that provides servo gun control and an integrated spot weld timer. The robot mounts on the floor or on a shelf mount and can be fitted with the A-Trac cable management system.

## Study notes

- SRA series robots are described as using Nachi FD controllers; no matching controller entry is available in the reference list.
- The SRA product line covers payloads from 100 kg to 240 kg, including standard floor-mount, invert-mount and long-reach models over 3 m.
- A hollow-arm version is available for internal routing of spot welding utilities (cooling water, weld power, signals, servo gun cables).
- Integrated spot weld timer is offered in AC and DC versions, programmable from the robot teach pendant with weld result storage for traceability.
- Pressure calibration supports up to 10 points across the spot welding range.
- Stated applications: material handling and spot welding. Stated mounts: floor and shelf mount.
- Aluminium spot welding solution is stated to give long tip life between dress cycles (>400 welds).
- An exclusive robot-mounted seam welder option is offered for continuous welds.
- The Axis 3 working envelope in the source table is inconsistent (radian values conflict with the parenthetical degree values), so Axis 3 ranges are omitted.
- The allowable static load torque table in the source is corrupted and is not reproduced here.
