11GL53 - WP-12 Gas Lens 5/32" (4.0mm) - 11GL53

Better Visibility and Cleaner Welds for Your WP-12 Torch

If you are running a WP-12 water-cooled torch, you are likely pushing serious amperage. When you are welding at 300, 400, or even 500 amps, turbulence in your shielding gas can be a nightmare, leading to contaminated welds and unstable arcs. The 11GL53 Gas Lens is the upgrade you need to smooth out that flow. Designed for 5/32" (4.0mm) tungsten, this gas lens replaces your standard collet body and transforms the way your gas exits the cup.

Why switch to a gas lens? It's all about the flow. Standard collet bodies dump gas out in a chaotic swirl, which can pull in outside air if you aren't careful. The 11GL53 uses a fine mesh screen to straighten that gas into a smooth, laminar column. This means you get a solid wall of argon protecting your puddle, even if there is a slight draft in the shop. The result is a shinier, cleaner bead with less post-weld cleanup required.

The biggest perk for the operator, however, is visibility. Because the gas stream is so stable, you can stick your tungsten out much further than you could with a standard setup—sometimes twice as far. This lets you see exactly where your arc is striking, which is a game-changer when you are trying to weld inside a tight fillet or reach the bottom of a deep V-groove. You stop guessing and start seeing.

Built to handle the intense heat of 500-amp welding, this gas lens is tough and reliable. It fits perfectly into your existing WP-12 torch head and works with your standard 5/32" collets. Whether you are welding heavy aluminum plate or thick stainless pipe, swapping in an 11GL53 gives you the control and confidence to lay down perfect beads pass after pass.
