0441452003 - ESAB 3.2mm (1/8") Gas Lens for TXH TIG Torches

See the Puddle, Weld the Gap

If you are struggling to see your weld puddle because your cup is in the way, or if you are getting gray, oxidized welds on stainless steel, it is time to switch to a gas lens. This ESAB 1/8" (3.2mm) Gas Lens (0441452003) is made for your TXH torch and is a game-changer for daily TIG work. Standard collet bodies just dump gas out of the cup, creating turbulence that can suck air into your weld if you stick the tungsten out too far. This gas lens fixes that problem entirely.

Inside the lens, a series of mesh screens smooths out the argon flow, creating a straight, calm column of gas that wraps around your tungsten and the weld pool. What does this mean for you? It means you can stick your tungsten out much further—sometimes nearly an inch—to reach into tight corners, fillets, or deep V-grooves while keeping your gas coverage perfect. It also helps keep your nozzle cooler and gives you a clearer view of the arc.

This part is designed for 1/8" tungsten, a common size for medium-to-heavy amperage work. Whether you are walking the cup on pipe or doing precision bench work, swapping your standard body for this ESAB gas lens will instantly improve your control and the look of your finished beads.
