FANUC ARC Mate 120iD/12L vs Yaskawa AR1440: Welding Robot Comparison
Updated: 10 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE Both are compared at 12 kg. FANUC ARC Mate 120iD/12L has the longer stated reach, which may help reach separated fixtures; it does not guarantee access at every tool angle. |
→ CONSIDER FANUC ARC Mate 120iD/12L Consider it when extra reach is useful while the compared load capacity is the same. This article compares 12 kg with a published reach of 2272 mm; include the gripper and part in the load. |
→ CONSIDER Yaskawa Motoman AR1440 Consider it when its stated load and reach already cover your task and its controls fit your equipment. This article compares 12 kg with a published reach of 1440 mm; include the gripper and part in the load. |
💡 THE TAKEAWAY Choose the robot that handles your actual tool and part through the required path, with controls and support your team can use. Compare complete installation quotes, rather than arm-only prices. |
The FANUC ARC Mate 120iD/12L and the Yaskawa Motoman AR1440 are both 12 kg welding robots for different part sizes. The ARC Mate 120iD/12L reaches 2272 mm. The AR1440 reaches 1440 mm, repeats more tightly and is listed at about a third of the price.
