D2GS418-P - CK Worldwide 2 Series Gas Saver Kit 1/8" (3.2mm) with Pyrex Cup

Technical Overview of the CK Worldwide D2GS418-P

The CK Worldwide D2GS418-P is a specialized Gas Saver™ front-end kit designed for the 2 Series TIG torch platform, which encompasses model numbers 9, 20, 25, and their equivalents. This kit is engineered to accommodate 1/8-inch (3.2mm) tungsten electrodes. The primary technical innovation of the Gas Saver system lies in its advanced gas lens collet body, which utilizes a porous screen media to laminarize the shielding gas flow. This reduction in turbulence allows for a more coherent gas column, effectively shielding the weld pool even at lower flow rates (CFM/LPM) compared to standard collet bodies.

The inclusion of a high-temperature Pyrex glass cup distinguishes this kit from standard ceramic setups. The transparent nozzle provides 360-degree visibility of the electrode and the arc, crucial for precision applications in confined spaces or when welding exotic alloys requiring strict contamination control. The kit replaces the standard front-end consumables on compatible torches, utilizing a wedge collet and tungsten adapter system that ensures positive electrical contact and thermal transfer.

By optimizing the gas distribution, the D2GS418-P minimizes the Venturi effect that often draws atmospheric oxygen into the weld zone during standard nozzle use. This results in cleaner welds with less oxidation, particularly on stainless steel and titanium, while simultaneously reducing argon consumption by up to 40%.
