KP2920-6 - Lincoln KP2920-6 Robotic Torch Breakaway Disk

Technical Overview of the Lincoln Electric KP2920-6

The Lincoln Electric KP2920-6 is a specialized Breakaway Disk designed for integration with through-the-arm robotic welding systems. In the realm of automated fabrication, the interface between the robotic manipulator and the welding end-effector is critical. This component serves as the mounting platform that secures the torch to the robot wrist while accommodating the internal cabling characteristic of hollow-wrist robots. The 'thru-the-arm' design is essential for modern manufacturing cells, as it reduces cable interference with fixtures and parts, thereby improving access to tight weld joints.

Functionally, the KP2920-6 acts as a safety device. It is engineered to disengage or signal a stop upon detecting excessive force, such as during a collision with a workpiece or fixture. This rapid response capability is vital for preserving the structural integrity of the welding torch neck and the sensitive servo motors of the robot arm. As an OEM part from Lincoln Electric, it guarantees precise dimensional tolerances, ensuring that the Tool Center Point (TCP) remains consistent relative to the robot's faceplate. This consistency is paramount for maintaining weld quality and reducing the need for frequent touch-ups or reprogramming after maintenance.

Constructed from durable materials capable of withstanding the thermal and mechanical stresses of an industrial welding environment, the KP2920-6 ensures long service life. It is compatible with specific Lincoln Electric robotic torch configurations intended for hollow-wrist manipulators. Proper installation of this disk is a prerequisite for the safe and accurate operation of the automated welding cell.
