18GL16 - Weldcraft 18GL16 1/16" Gas Lens Collet Body for WP-18SC Torches (2-Pack)

Precision Gas Shielding for High-Performance TIG Welding

The Weldcraft 18GL16 Gas Lens Collet Body is a critical component designed to elevate the performance of WP-18SC and W400 TIG welding torches. Engineered for use with 1/16-inch (1.6mm) tungsten electrodes, this gas lens replaces standard collet bodies to fundamentally change how shielding gas is delivered to the weld zone. By utilizing a multi-layer mesh screen, the 18GL16 rectifies the turbulent flow of gas from the torch into a coherent, laminar stream. This reduction in turbulence is essential for maintaining a pure inert atmosphere around the molten weld pool, minimizing the risk of porosity and oxidation caused by atmospheric contamination.

One of the significant technical benefits of using the 18GL16 gas lens is the ability to extend the tungsten electrode further beyond the nozzle cup without compromising shielding gas coverage. In standard setups, extending the electrode too far can lead to turbulent eddies that pull oxygen into the shield. However, the laminar column created by this gas lens remains stable over a greater distance. This feature is particularly advantageous when welding in tight corners, deep grooves, or complex geometries where the nozzle cup would otherwise obstruct the operator's view or contact the workpiece.

Manufactured to Weldcraft's exacting standards, the 18GL16 ensures optimal electrical conductivity and thermal transfer, which is vital for the high-amperage applications typically associated with the WP-18SC series torches. The component is machined for a precise fit, ensuring that the collet grips the tungsten securely to prevent slippage and ensure consistent arc starting. This package contains two gas lens collet bodies, providing professional fabricators with the necessary spares to maintain uninterrupted production cycles.

Whether working with stainless steel, aluminum, or exotic alloys, the control provided by the Weldcraft 18GL16 allows for cleaner welds, reduced post-weld cleaning, and improved overall joint quality. It is an indispensable upgrade for operators seeking to maximize the capabilities of their water-cooled TIG torch systems.
