0157121033 - ESAB 53N59 #5 Alumina Gas Lens Cup for 9/20 Torches

Get Better Coverage with the ESAB 53N59 #5 Cup

If you are looking to step up your TIG game, switching to a gas lens setup is one of the best upgrades you can make for your WP-9 or WP-20 torch. The ESAB 53N59 is the Size #5 (5/16") alumina cup designed specifically for that purpose. Unlike standard cups that just dump gas out, this nozzle works with your gas lens to smooth out the flow, giving you that buttery-smooth laminar coverage that makes stacking dimes so much easier.

Why does this matter? With the laminar flow provided by this nozzle setup, you can stick your tungsten out significantly further—sometimes up to an inch depending on conditions—without losing your gas shield. This is a game-changer when you are trying to weld inside a corner, a deep V-groove, or around a roll cage tube where a standard cup would block your view. The #5 size is perfect for general-purpose work on thinner materials where you want a tight gas column to keep the heat affected zone clean.

Made from durable pink alumina ceramic, this cup handles the heat of daily welding while resisting spatter adhesion. Whether you are working on a custom exhaust, fixing a mold, or practicing your root passes, the 53N59 gives you the visibility and gas protection you need to lay down perfect beads every time. Don't settle for turbulence; upgrade your front-end parts and see the difference.
