45V25 - 45V25 Medium Gas Lens 1/16" (1.6mm) for 17/18/26 Series Torches (2-Pack)

Upgrade Your TIG Torch Performance

Take your TIG welding to the next level with the 45V25 Medium Gas Lens, designed for 1/16" (1.6mm) tungsten electrodes. If you are tired of struggling with turbulence, poor visibility, or inconsistent gas coverage, swapping your standard collet body for a gas lens is one of the most effective upgrades you can make. This 2-pack of high-quality generic replacements fits all standard 17, 18, and 26 series torches, making it a versatile addition to your welding kit whether you are using an air-cooled or water-cooled setup.

Why Use a Gas Lens?
The magic lies in the mesh screens inside the lens. Unlike a standard collet body that just dumps gas out of the nozzle, the 45V25 smooths out the flow into a calm, straight column. This "laminar flow" means your shielding gas hugs the weld puddle much more effectively, keeping oxygen and nitrogen out. The result? Cleaner, shinier welds with less discoloration and reduced post-weld cleaning. It is especially helpful when welding stainless steel, titanium, or aluminum, where gas coverage is critical to success.

Reach Tight Spots Easily
One of the biggest frustrations in welding is not being able to see the puddle because the nozzle gets in the way. With the 45V25 gas lens, you can extend your tungsten stick-out much further than with a standard setup—often up to an inch—while still maintaining excellent shielding. This allows you to get into tight corners, fillets, and narrow gaps while keeping a clear line of sight on your arc. It’s a game-changer for roll cages, manifolds, and intricate artistic work.

Cost-Effective Quality
These generic replacements offer the performance of premium brands without the premium price tag. They are engineered to meet or exceed OEM specifications for fit and function. By improving your gas efficiency and reducing rework caused by porosity, these gas lenses pay for themselves over time. Whether you are a seasoned pro or just learning the ropes, the 45V25 will help you lay down smoother, more consistent beads with confidence.
