OVERVIEW

Unmatched Visibility and Gas Coverage

Take your TIG welding precision to the next level with the CK Worldwide D4GS418LD Gas Saver Kit. If you have ever struggled to see the weld pool behind a bulky ceramic cup or fought with turbulence affecting your gas coverage, this kit is the solution. The centerpiece of this system is the Large Diameter Glass Cup, which acts like a window to your work. Whether you are welding inside a corner or maneuvering around complex tubing, the transparent nozzle ensures you never lose sight of the arc.

Extended Stick-Out Capabilities
Standard gas lenses are good, but the CK Gas Saver is better. The oversized diffusion screen creates such a stable column of gas that you can extend your tungsten stick-out up to 6 times the electrode diameter. This incredible reach allows you to weld in deep recesses and tight joints that would be impossible to access with a standard setup, all while maintaining perfect shielding to prevent porosity and oxidation.

Perfect for Titanium and Stainless
For welders working with titanium, Inconel, or high-grade stainless steel, gas coverage is everything. The D4GS418LD provides a wide, uniform gas envelope that protects the heat-affected zone more effectively than standard nozzles. This kit allows you to weld titanium tubing at low amperages without the hassle of setting up a trailing shield, saving you time and equipment costs. Compatible with all 4 Series torches (17, 18, 26, CS300, etc.), this kit is a plug-and-play upgrade for your daily driver torch.

FAQ

This kit is designed for 4 Series torches, which includes popular models like the 17, 18, 26, 150, 210, 300, 510, and equivalent torches from other manufacturers.

This specific kit (D4GS418LD) is configured for 1/8" (3.2mm) tungsten electrodes.

The CK Gas Saver kit can save up to 40% of shield gas consumption compared to standard collet body setups due to its efficient diffusion screen.

The cup is made of high-temperature glass (Pyrex style). While it withstands high heat, it is glass and can break if dropped or impacted. It is replaceable (Part # CK4P18GSLD).

It is generally not recommended to 'walk the cup' on glass nozzles as the friction and texture of the base metal can damage the glass or cause it to break. It is best used for freehand welding.

The large diameter diffusion screen provides a very wide and stable gas shield, which is essential for preventing atmospheric contamination when welding reactive metals like titanium.

Yes, this kit replaces your standard collet body, collet, and cup with the Gas Saver system components (collet body, tungsten adapter, screen, and glass cup).

With the improved laminar flow provided by the Gas Saver, you can extend the tungsten up to 6 times the electrode diameter beyond the cup edge.
