22-7 - Miller Weldcraft 22-7 Replacement Collet Knob for WP-22/23 Torches

Precision Component for High-Performance TIG Torches

The Miller Weldcraft 22-7 Collet Knob is a specialized replacement component engineered specifically for the WP-22 and WP-23 series of TIG torches. In the realm of precision welding, particularly when utilizing water-cooled or automated torch systems like the WP-22 and WP-23, every component plays a pivotal role in the overall stability and quality of the arc. This collet knob is not merely a fastener; it is the mechanical interface that secures the collet within the torch body, ensuring that the tungsten electrode is held firmly in place during operation.

Manufactured to Miller's exacting standards, the 22-7 knob is constructed from high-grade materials capable of withstanding the thermal cycles and mechanical stresses inherent in industrial welding environments. The WP-22 and WP-23 torches are often employed in demanding applications where consistency is paramount. A worn or ill-fitting collet knob can lead to loose electrodes, poor electrical conductivity, and unstable gas coverage, all of which compromise weld integrity. By utilizing this genuine OEM part, operators ensure that the internal geometry of the torch head remains aligned, facilitating optimal current transfer from the power source to the tungsten.

Installation of the 22-7 is straightforward, featuring a design that allows for secure tightening without the need for excessive force that could damage torch threads. Its form factor is specifically matched to the rear assembly of the compatible torch models, providing a flush and secure fit that prevents gas leakage. For maintenance personnel and welding engineers responsible for the upkeep of high-amperage TIG equipment, stocking genuine replacements like the 22-7 is essential for minimizing downtime and maintaining equipment certification standards. This component represents the reliability and quality synonymous with the Weldcraft brand, ensuring your equipment performs as designed.

Whether used in manual fabrication or mechanized setups, the integrity of the torch assembly dictates the quality of the output. The 22-7 Collet Knob is a small but critical piece of that assembly, safeguarding the connection between the collet and the torch body. Trust in genuine Miller parts to maintain the precision required for aerospace, motorsports, and critical pipe welding applications where the WP-22 and WP-23 torches are frequently utilized.
