The Fanuc ARC Mate 120iC is a 6-axis industrial robot built for high-speed arc welding and cutting, with a 20 kg payload, 1811 mm horizontal reach and ±0.04 mm repeatability (ISO 9283). It is one of the most widely deployed mid-size welding robots in automotive, metal fabrication and contract welding shops worldwide.

Why integrators choose the ARC Mate 120iC

The protected internal cabling, slim wrist and clean tool-side connections make this model fast to commission and easy to maintain. Combined with the latest R-30iB controller, it delivers reliable cycle times across MIG/MAG, TIG, plasma and laser welding processes.

R-30iB controller — at a glance

• 250+ integrated software functions — Arc Tool, TouchSensing, ThruArc Seam Tracking, Coordinated Motion.
• iPendant Touch — intuitive teach pendant with multi-window navigation and on-screen diagnostics.
• Integrated PMC — high-performance soft PLC for cell-level I/O without an external PLC.
• Compact & stackable — floor, wall or rack mounting; lower energy consumption vs. previous generation.
• Hardened security — Fanuc proprietary firmware, no exposure to standard PC malware.

How we deliver this robot

The ARC Mate 120iC is supplied refurbished and tested, ready to be integrated into a custom welding cell sized to your part flow. We can pair it with a Fronius, Lincoln, Kemppi or AOTAI welding source, single- or twin-positioner, fume extraction, fencing and HMI — everything specified together with your engineering team.

Robot only — cell configuration is engineered on request based on parts, cycle time and shop layout.
