13N23L - Miller Weldcraft 13N23L 3/32 Inch Gas Lens Collet 2-Pack

Weldcraft 13N23L Gas Lens Collet Overview

The Weldcraft 13N23L is a specialized gas lens collet designed for precision TIG welding applications. Engineered to accommodate 3/32-inch (2.4mm) tungsten electrodes, this component is a critical part of the front-end assembly for 9, 20, and 25 series TIG torches. Unlike standard collets, this gas lens collet is specifically manufactured to work within a gas lens body assembly, playing a pivotal role in current transfer and electrode positioning.

Manufactured by Miller Electric under the Weldcraft brand, this part ensures strict adherence to dimensional tolerances and material quality. The collet functions by clamping securely onto the tungsten electrode when the back cap is tightened, ensuring consistent electrical conductivity and preventing electrode slippage during operation. Its design is optimized to work in conjunction with gas lens bodies to reduce turbulence in the shielding gas stream.

Technical Compatibility

This collet is compatible with a wide range of air-cooled and water-cooled torches. Specifically, it fits:

• 9 Series: Air-cooled torches (125A)
• 20 Series: Water-cooled torches (250A)
• 25 Series: Water-cooled torches

It is essential to pair this collet with the appropriate gas lens body (e.g., 45V44) and gas lens nozzle to achieve the intended performance benefits. It is not designed for use with standard collet bodies.

Operational Benefits

The 13N23L facilitates the use of gas lenses, which provide a laminar flow of shielding gas. This laminar flow is far superior to the turbulent flow created by standard nozzle setups. By smoothing out the gas stream, the operator can extend the tungsten electrode further past the cup—often up to an inch or more depending on conditions—without compromising the inert atmosphere around the weld pool. This capability is indispensable for industrial MRO tasks requiring welding in recessed areas, corners, or complex pipe geometries.

Supplied in a pack of two, these collets are consumable items that should be replaced if they show signs of arc damage, deformation, or loss of clamping force. Maintaining fresh collets ensures the longevity of the torch head and the quality of the weld arc.
