KP2920-5 - Lincoln Electric Thru-Arm Robotic Breakaway Disk KP2920-5

Precision and Protection for Automated Welding

The Lincoln Electric KP2920-5 Breakaway Disk is a specialized component engineered for the demanding environment of industrial robotic welding. Designed specifically for thru-the-arm robotic configurations, this disk serves as the critical mechanical interface between the robot's wrist and the welding torch assembly. In modern automation, where precision and uptime are paramount, the integrity of the torch mounting system is essential for maintaining consistent weld quality and protecting capital equipment.

Thru-the-arm robotic systems, often utilizing hollow-wrist robots, are favored for their ability to protect cabling and improve access to tight spaces. The KP2920-5 is tailored to this architecture, ensuring that the welding gun is securely mounted while accommodating the internal cable routing that defines these systems. As a genuine Lincoln Electric OEM part, it guarantees seamless compatibility with Lincoln's ecosystem of robotic torches and peripherals, eliminating the fitment issues often associated with aftermarket alternatives.

Critical Safety Functionality

One of the primary roles of the KP2920-5 is to act as a safety device. In the event of a torch collision—whether with the workpiece, a fixture, or an external obstruction—the breakaway disk is designed to disengage or trigger a stop mechanism, thereby minimizing damage to the expensive robot arm and the welding torch itself. This "mechanical fuse" capability is vital for preserving the longevity of the automation cell and reducing the costs associated with severe equipment crashes.

Maintaining Tool Center Point (TCP)

Beyond safety, the KP2920-5 is integral to maintaining the Tool Center Point (TCP). In robotic welding, the robot must know exactly where the tip of the wire is to track seams accurately. A high-quality breakaway disk ensures that the torch returns to its precise zero position after minor impacts or maintenance routines. This repeatability reduces the need for frequent reprogramming and touch-ups, ensuring that your production line maintains its cycle times and quality standards. By investing in the KP2920-5, facilities ensure their Lincoln Electric robotic cells operate at peak efficiency with maximum protection.
