FANUC M-710iC/20M vs Yaskawa AR3120: 20 kg Robot Comparison
Updated: 10 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE Both are compared at 20 kg. Yaskawa Motoman AR3120 has the longer stated reach, which may help reach separated fixtures; it does not guarantee access at every tool angle. |
→ CONSIDER FANUC M-710iC/20M Consider it when its stated load and reach already cover your task and its controls fit your equipment. This article compares 20 kg with a published reach of 2582 mm; include the gripper and part in the load. |
→ CONSIDER Yaskawa Motoman AR3120 Consider it when extra reach is useful while the compared load capacity is the same. This article compares 20 kg with a published reach of 3124 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 M-710iC/20M and the Yaskawa Motoman AR3120 both carry 20 kg and weigh about 550 kg. The AR3120 reaches 3124 mm, about 540 mm further, and is a dedicated welding robot listed at well under half the price.
Quick verdict. The Yaskawa AR3120 is the better value for welding large parts, with 3124 mm and a listed price $40,000 lower. The FANUC M-710iC/20M is the better choice for handling, sealing and laser cutting within 2.6 m.
