0700300453 - ESAB RT 62G Robotic Torch Neck, 22 Degree, Gas Cooled

Technical Overview of the ESAB RT 62G Torch Neck

The ESAB RT 62G Torch Neck (SKU: 0700300453) is a specialized component designed for the RT series of robotic MIG welding guns. This specific model features a 22-degree bend angle, identified by the designation "22DEG," and is engineered for gas-cooled applications ("62G"). The neck serves as the primary conduit for welding wire, shielding gas, and welding current, bridging the gap between the cable assembly and the contact tip. It is manufactured to strict dimensional tolerances to ensure compatibility with automated systems where precision is paramount.

Constructed from high-grade copper alloys, the neck offers excellent electrical conductivity and thermal dissipation, essential for maintaining arc stability during prolonged welding cycles. The gas-cooled design relies on the flow of shielding gas to manage operating temperatures, making it suitable for standard to medium-heavy duty robotic applications where water cooling is not required. The 22-degree angle provides a specific tool orientation that differs from the standard 45-degree or straight necks, allowing the robot to access joints that may be obstructed by fixtures or part geometry.

In robotic welding, the Tool Center Point (TCP) is a critical variable. The ESAB RT 62G neck is built to ensure that when a replacement is installed, the TCP remains consistent within a very small tolerance window. This minimizes the need for extensive reprogramming or "touch-ups" of the robot's path after maintenance. The neck includes robust insulation materials to prevent electrical shorting against the workpiece or fixtures, a common risk in automated cells. This part is a direct OEM replacement, ensuring full compatibility with the existing RT 62G torch body and consumable ecosystem.
