MOTOMAN YASKAWA AR3124
Robot details
The YASKAWA MOTOMAN AR3120 is an ultra-long-reach 6-axis industrial robot designed for large-scale arc welding and thermal cutting applications. Featuring a remarkable 3,124 mm working reach and a 20 kg payload capacity, the AR3120 is specifically engineered for welding oversized components, deep structures, heavy fabrications, construction equipment, agricultural machinery, and large industrial assemblies.
As one of the largest robots in the MOTOMAN AR Series, the AR3120 combines exceptional path accuracy, advanced motion performance, and superior accessibility. Its extended arm geometry allows the robot to reach difficult weld locations while maintaining precise torch positioning throughout the welding process.
The robot is powered by the advanced YRC1000 controller, offering high-speed processing, intelligent trajectory control, advanced welding functions, multi-axis synchronization, and full Industry 4.0 compatibility. This combination delivers superior welding quality, reduced cycle times, and increased manufacturing efficiency.
The AR3120 incorporates a hollow through-arm design, allowing cables, welding hoses, and wire feeding systems to be routed internally through the robot arm. This reduces cable wear, minimizes interference, improves accessibility, and increases reliability in demanding industrial environments.
Its slim and streamlined arm structure allows easy access to complex workpieces while minimizing interference with fixtures, positioners, and surrounding equipment. The robot is particularly effective in automated welding cells where large welding envelopes are required.
The AR3120 is ideal for manufacturers seeking a long-reach robotic welding solution capable of handling large parts while maintaining the precision and repeatability expected from YASKAWA's advanced welding robot technology.
