FANUC ARC Mate 120iB
ARC Mate 120iB Information

Suitable for high-speed welding and cutting processes, the FANUC ARC Mate 120iB is a six-axis robotic arm that is servo-driven. The FANUC 120iB RJ3iB welding robot provides accurate and consistent path performance based on its simple and reliable construction.

In addition to high-speed cutting and welding, the ARC Mate 120iB is capable of performing a variety of welding applications, including MIG welding, TIG welding, Plasma welding and Plasma cutting.  

The 120iB is the best in its class for reach versus stroke ratio and fastest motion speeds. The exceptionally fast wrist axes reduce air cut times, and the ARC Mate has an extremely large work envelopes and complex tooling.

The FANUC ARC Mate 120iB uses the FANUC RJ3iB controller and has a user-friendly teach pendant, making training easier. The system has the ability to be equipped with an air-cooled welding torch, ArcLink interface, safety holder and wire feeder.

RobotWorx also offers a wide variety of used robots, including the reconditioned ARC Mate 120iB.  All of the used robots go through a thorough reconditioning process. All new and used ARC Mate 120iB robots include the RobotWorx Value Package. Compatible with all major brands of welding equipment, the new and used FANUC ARC Mate 120iB RJ3iB  is capable of plug-and-play with Lincoln Electric welding power sources.  Overall, both the new and used ARC Mate 120iB can decrease cycle times and increase consistency, improving the quality of the weld.
