Fanuc ARC Mate 120iD Welding Robot

Speed, accuracy and maximum access

An ideal all-round welding robot, the Fanuc ARC Mate 120iD robot’s slim articulated design means it excels at welding in narrow jigs. It features a new drive train for significantly higher axis speeds and, thanks to its high rigidity, boasts a repeatability of ± 0.02 mm. For maximum operating flexibility, it has a large working envelope and can reach in very close to its own base. By combining Fanuc reliability with higher motion performance, the Fanuc ARC Mate 120iD maximizes productivity and enhances your profitability. Operating costs are low, and installation is easy.
