13N22L - 1/16" Large Diameter Gas Lens Collet for 9/20 Series Torches

Technical Overview of the 13N22L Gas Lens Collet

The Generic 13N22L is a specialized TIG welding collet designed for use with 1/16-inch (1.6mm) tungsten electrodes in conjunction with large diameter gas lens bodies. This component is critical for maintaining the electrical contact between the power source and the tungsten electrode while positioning the electrode within the torch head. It is manufactured to precise tolerances to ensure a secure grip on the tungsten, minimizing arc instability and maximizing current transfer efficiency.

This collet is specifically engineered for compatibility with 9, 20, and 25 series TIG torches (air-cooled and water-cooled variants). Unlike standard collets, the 13N22L is intended for gas lens setups, which utilize a mesh screen to create a laminar flow of shielding gas. This laminar flow significantly reduces turbulence compared to standard nozzle setups, providing superior protection of the weld pool against atmospheric contamination. The design of this collet supports the gas lens assembly, ensuring concentric alignment of the electrode within the gas stream.

Constructed from high-quality copper alloy, the 13N22L offers excellent thermal and electrical conductivity. This material choice helps dissipate heat generated during the welding process, prolonging the life of the consumable and preventing deformation under high-amperage loads. The collet's geometry allows for extended tungsten stick-out, enabling the welder to access deep grooves or tight corners without compromising gas shielding coverage. This part is a direct replacement for the standard 13N22L specification found in Weldcraft and other major TIG torch systems.
