Long Reach Arc Welding Robot

The AII-V6L shares many of the same features as the AII-V6 arc welding robot, and additionally features a longer arm for increased reach and is ideal for working with large fixtures. And like the other AII Series robots, the AII-V6L also features individual servo shock sensors on each AIIis to prevent damage to robot.

AX21 Robot Controller Base

The AII series robots are powered by the new AX21 controller, which features improved resistance to heat and dust, improved reliability in global environments, improved reliability and maintainability, increased sampling frequency for higher detection accuracy, and more.

Notes

1. Positional repeatability calculated after operating conditions stabilize from repeated automatic operations.
2. The value shown in ( ) indicates wall-mounted conditions.
3. Positional data protected by battery-backed storage inside the manipulator.
4. When the output flange of the wrist axis is loaded with maximum payload capacity.
5. Working range of J6 axis may be restricted by the position of J5 axis.
