FANUC ARC Mate 120iD industrial robot with R-50iA controller
FANUC ARC Mate 120iD with R-50iA controller is a high-payload 6-axis arc-welding robot from the ARC Mate family. It has a rated wrist payload of 25 kg and a maximum working reach of 1831 mm.
Variant name / also known as: FANUC ARC Mate/25-18D.
The ARC Mate family is part of FANUC's range of dedicated arc-welding robots. It is intended for MIG/MAG and TIG welding, brazing, thermal processing and related path applications. The mechanical configuration of this model is identified as Standard, allowing the robot to be selected for a clearly defined combination of payload, reach and installation layout.
This model uses 6 controlled axes and has a published positioning repeatability of ±0.02 mm. Its stated mounting arrangement is floor, upside-down or angle. Final payload capacity must be checked against the complete tool, workpiece, center-of-gravity and inertia data rather than the nominal wrist payload alone.
Controller compatibility: the model is listed for the R-50iA control generation. For CMS classification, all supported cabinet forms are consolidated under the single controller name R-50iA. Electrical supply, cabinet size, safety options, fieldbus interfaces, software packages and regional availability still have to be confirmed for the exact robot order code.
Typical applications
- advanced manufacturing
- arc welding
- handling of parts
For a Eurobots project, FANUC ARC Mate 120iD can be evaluated for new automation, controller-standardization studies, replacement projects, process trials and complete robotic cells. Engineering approval should be based on the exact mechanical-unit specification, load diagram, mounting orientation, environmental option and controller software release.
