D3GS418-P - CK Worldwide Large Diameter Gas Saver Kit 1/8" with Pyrex Cup

Precision TIG Welding with Enhanced Visibility

The CK Worldwide D3S418-P Large Diameter Gas Saver Kit is a premium aftermarket accessory designed to upgrade standard TIG torches (Series 17, 18, and 26) for high-performance welding applications. This kit is specifically engineered for use with 1/8" (3.2mm) tungsten electrodes, providing a complete solution for welders seeking better gas coverage and visual control over their work.

At the core of this system is CK Worldwide's proprietary Gas Saver technology. Unlike standard collet bodies that can create turbulent gas flow, the Gas Saver utilizes a specialized screen adapter to generate a coherent, laminar column of shielding gas. This laminar flow is critical for preventing atmospheric contamination of the weld pool, even when the tungsten stick-out is extended significantly beyond the nozzle. By reducing turbulence, users can often lower their flowmeter settings, resulting in argon savings of up to 40% over time.

The inclusion of a Pyrex (borosilicate) glass cup distinguishes this kit from standard ceramic setups. The clear nozzle allows the operator to see the tungsten tip and the weld puddle from virtually any angle, eliminating blind spots often caused by opaque ceramic cups. This is particularly advantageous when welding in tight corners, inside pipes, or on intricate aerospace components where precision is paramount. The large diameter of the cup ensures a broad umbrella of shielding gas, making it ideal for reactive metals like titanium or stainless steel where heat-affected zone protection is critical.

This kit comes complete with all necessary components to convert a standard 3-Series torch front end, including the screen adapter, collet, O-ring, heat shield, and the glass cup itself. It is a direct replacement for standard parts on air-cooled (17, 26) and water-cooled (18) torches.
