K4251-MA1440-B - Lincoln Electric MA1440 Arc Welding Robot Manipulator

Precision Automation with the MA1440

The Lincoln Electric K4251-MA1440-B Yaskawa Motoman Robotic Arm represents the pinnacle of arc welding automation technology. Designed to integrate seamlessly with Lincoln Electric's advanced Power Wave® power sources, this manipulator is engineered to deliver consistent, high-quality welds in high-production environments. The MA1440 is a 6-axis articulated robot that combines speed, precision, and a compact footprint, making it an ideal choice for manufacturers looking to optimize their welding cells.

One of the standout technical features of the MA1440 is its patented hollow upper arm design. This innovation allows the welding torch cabling to be routed internally through the arm, rather than strapped to the exterior. This significantly reduces cable interference with fixtures and workpieces, minimizes cable flip, and extends the lifespan of the torch cable package. With a payload capacity of 6 kg, it easily accommodates standard welding torches and sensors without compromising its rapid acceleration capabilities.

The robot boasts a horizontal reach of 1440 mm and a vertical reach of 2511 mm, providing a generous work envelope for a wide variety of parts. Its slim profile allows for high-density layouts, enabling multiple robots to work in close proximity without collision. The MA1440 is renowned for its high-speed motion, which drastically reduces air-cut time—the time the robot spends moving between welds—thereby increasing overall cycle throughput. With a repeatability of ±0.08 mm, it ensures that every weld path is executed with exacting precision, maintaining strict quality control standards across thousands of cycles.

Installation flexibility is another key advantage, with support for floor, ceiling, and wall mounting configurations. This versatility allows system integrators to design welding cells that maximize floor space and accessibility. Whether used for MIG or TIG applications, the Lincoln Electric MA1440 provides the durability and performance required for modern industrial fabrication.
