11GL18 - Miller Weldcraft 11GL18 Gas Lens 1/8" for WP-12 Torches

Upgrade Your WP-12 Torch Performance

Take your TIG welding to the next level with the Miller Weldcraft 11GL18 Gas Lens. If you are running a heavy-duty WP-12 water-cooled torch, you know that managing heat and gas coverage at high amperages (up to 500A) is a challenge. This 1/8-inch (3.2mm) gas lens is the solution professional welders trust to smooth out their gas flow and improve weld quality.

Why Switch to a Gas Lens?

Standard collet bodies are fine for basic work, but they often let shielding gas exit the nozzle in a turbulent cloud. This turbulence can pull in outside air, contaminating your weld. The 11GL18 Gas Lens fixes this by using a series of fine mesh screens to organize the gas into a smooth, straight column—known as laminar flow. This means your weld pool stays protected, even if you are welding in a drafty shop or moving quickly.

Reach Tight Spots Easily

One of the biggest perks of using the 11GL18 is the ability to extend your tungsten stick-out. Because the gas stream is so stable, you can push your tungsten out much further than with a standard collet body. This lets you reach into deep corners, V-grooves, and tight angles while still keeping the puddle perfectly shielded. It also gives you a better view of what you are doing, which leads to better-looking beads and fewer mistakes.

Genuine Miller Quality

When you are pushing 500 amps, you can't afford to use cheap knock-off parts that might melt or arc out. This is a genuine Miller Weldcraft part, built tough with high-grade brass and copper to handle the heat. It fits perfectly with your existing WP-12 setup and 1/8" tungstens. Whether you are welding thick aluminum or heavy stainless steel plate, the 11GL18 gives you the control and reliability you need to get the job done right the first time.
