KP4378-22 - AutoDrive SA 22-Degree Water-Cooled Gun Tube

Precision Engineering for Automated Welding

The Lincoln Electric KP4378-22 AutoDrive SA 22° Robotic Gooseneck is a critical component designed to maintain the high standards of precision required in modern automated manufacturing. Engineered specifically for the AutoDrive® SA robotic torch system, this gun tube serves as the conductive conduit for welding wire, directing it with exacting accuracy to the weld joint. The "SA" designation in the AutoDrive series typically refers to Servo Torch technology, implying that this component is part of a highly responsive and precise wire delivery system used in advanced fabrication sectors.

This specific model features a 22-degree bend angle. In robotic path programming, the angle of the gooseneck is a fundamental variable that dictates the robot's ability to access joints, particularly in complex fixtures or tight spaces. A 22-degree angle provides a straighter profile compared to standard 45-degree necks, offering unique reach capabilities for specific part geometries. The structural integrity of the KP4378-22 is paramount; it is built to withstand the mechanical stresses of rapid robotic movements and sudden acceleration/deceleration without deflecting, thereby ensuring that the Tool Center Point (TCP) remains constant. TCP stability is essential for preventing weld defects and reducing the need for frequent reprogramming or touch-ups.

Furthermore, the description indicates this is a Water-Cooled (W/C) unit. Water cooling is indispensable in high-duty-cycle robotic applications where air-cooled torches would overheat. By effectively circulating coolant through the neck, the KP4378-22 dissipates the intense heat generated by the welding arc and electrical resistance. This thermal management protects internal components, prevents the premature failure of the front-end consumables (contact tips, nozzles), and ensures consistent electrical conductivity for a stable arc.
