D3GS418 - CK Worldwide 3 Series Gas Saver Kit 1/8" Alumina

See the Puddle, Save the Gas

Every TIG welder knows the frustration of trying to weld in a tight corner or a deep fillet where the cup gets in the way, blocking your view of the puddle. The CK Worldwide D3GS418 Gas Saver Kit is the solution to that headache. By replacing your standard collet body with this advanced gas lens system, you can extend your tungsten out much further—up to six times the diameter of the electrode—while still keeping your weld completely shielded. This means for a 1/8" tungsten, you can have nearly 3/4" of stick-out, giving you unmatched visibility and access to hard-to-reach joints without the risk of porosity.

Upgrade Your 17, 18, or 26 Torch

If you are running a standard 17, 18, or 26 series torch (or any 3 Series equivalent), this kit is a direct drop-in upgrade. You don't need to buy a new torch to get better performance; you just need better consumables. The Gas Saver kit replaces your existing front-end parts with a high-performance setup that smooths out the gas flow. This laminar flow is so efficient that you can actually turn down your flowmeter. Many welders report saving up to 40% on their argon bill, which means fewer trips to swap out cylinders and more time burning metal.

Durable Alumina Cup Design

While some gas lens kits come with glass cups for demonstration purposes, the D3GS418 is built for the real world. It comes with a #7 Alumina cup, which is a tough ceramic material capable of withstanding the high heat and abuse of daily welding. Whether you are walking the cup on pipe or performing freehand precision work, the Alumina cup holds up to the heat. The kit includes everything you need to switch over: the heatshield, the specific 1/8" collet and body, the tungsten adapter, and the cup itself.

Better Welds, Less Hassle

Turbulence is the enemy of a clean TIG weld. Standard collet bodies often swirl the gas, pulling in atmospheric contamination if you stick the tungsten out too far. The CK Gas Saver eliminates this turbulence, providing a wide, calm umbrella of shielding gas. This results in cleaner welds with less oxidation, even on sensitive materials like stainless steel and titanium. If you are welding with 1/8" tungsten and want to step up your game, this kit is one of the most cost-effective upgrades you can make to your welding rig.
