2AG10 - CK Worldwide 2AG10 #10 Alumina Gas Lens Cup (10 Pack)

Upgrade Your TIG Torch with #10 Gas Lens Cups

If you are looking to improve your weld color and consistency on stainless steel, switching to a gas lens setup with a larger cup like the CK 2AG10 is one of the best moves you can make. This #10 Alumina Cup features a 5/8-inch opening, giving you a wide puddle of argon coverage that keeps your weld zone clean and free from oxidation. The pink alumina ceramic is tough—it handles the heat of high-amperage TIG welding without cracking and resists spatter build-up better than cheaper alternatives, meaning you spend less time cleaning your torch and more time welding.

This cup is designed to fit the "2 Series" torches, which are the smaller, lightweight torches often referred to as the 9 or 20 style. If you are running a gas lens collet body (which uses a fine mesh screen to straighten out your gas flow), this is the cup that screws onto it. The #10 size is particularly popular for "walking the cup" on pipe or when you need to extend your tungsten out a bit further to see into a fillet weld. The laminar flow created by the gas lens/cup combo allows that extra stick-out without sucking in air.

These cups come in a convenient pack, ensuring you have replacements on hand when you need them. Whether you are a pipe welder, a fabricator, or a hobbyist looking for that stack-of-dimes look, the CK 2AG10 provides the gas coverage necessary for professional-grade results. It fits a wide range of torches including the CK9, CK20, WP9, WP20, and many others found in shops across the country.
