KP2918-22 - Lincoln Electric KP2918-22 22-Degree Robotic MIG Gun Neck

Precision Engineering for Automated Welding

The Lincoln Electric KP2918-22 is a specialized 22° Thru-Arm Gooseneck designed for robotic MIG welding applications. Often associated with Tregaskiss-style robotic guns, this gun tube is an essential component for maintaining the precision and repeatability required in automated welding environments. The "gooseneck" or "neck" of the MIG gun is the final conduit for the welding wire before it reaches the contact tip, and its geometry plays a crucial role in both wire feedability and torch accessibility.

This model features a shallow 22-degree bend. While 45-degree and 60-degree necks are common, a 22-degree neck offers a straighter approach that can be advantageous for welding into deep grooves or accessing joints with limited clearance where a sharper bend might cause the torch body to collide with the workpiece or fixture. The "Thru-Arm" designation indicates that this neck is designed for robotic torches where the power cable runs internally through the robot's arm, a standard in modern manufacturing to protect cables from snagging and fatigue.

Replacing a damaged or worn gooseneck is vital for maintaining the Tool Center Point (TCP). A bent or distorted neck will cause the wire to deviate from the programmed path, leading to weld defects and the need for reprogramming. The KP2918-22 is manufactured with tight tolerances to ensure that when you swap out a neck, your TCP remains consistent. It is compatible with standard consumables (diffusers, nozzles, tips) typically used in these robotic setups, allowing for easy integration into your existing inventory of spare parts.
