Protection class IP67

The extra smooth surfaces on the Fanuc ARC Mate 120iD series help minimise spatter build up. IP67 protection on the wrist axes protect the robot against moisture and dust, making it the ideal candidate for dirty welding or cutting applications.

Smart offline programming

This robot model is integrated into the Fanuc's own offline programming software Roboguide, a powerful tool that enables integrators, planners and users to design cells, systems and motions offline.
