The CK D4GS418LD Gas Saver kit is a large-diameter clear-cup kit for 1/8 inch (3.2 mm) tungsten on compatible CK17, CK18 and CK26 torches. Its clear glass cup improves visibility around the joint and works with matched shielding-gas distribution components.
4 Series components for 3 Series torches
The kit uses CK’s 4 Series Gas Saver components on 3 Series torch models. Keep the complete D4GS418LD part number when ordering: the accessory-family number and torch-family number describe different parts of the setup.
- Kit: D4GS418LD

Set up for the welding procedure
Confirm the torch and tungsten size before fitting the kit. Choose gas flow and electrode extension for the joint, material and surrounding conditions. The larger cup does not guarantee a fixed gas saving or establish a universal stick-out allowance.
Use the matched components as an assembly; sharing a cup diameter does not make different kit families interchangeable. Clear-cup visibility does not replace required welding eye protection.
Spare cup and other torch families
The corresponding replacement cup is 4P18GSLD. For a CK9/CK20 2 Series torch with 1/8 inch tungsten, compare the separate D2GS418LD kit. Contact Justram with your existing torch and kit details if you need help identifying parts.
