45V43 - 45V43 Gas Lens 1/16" for 9/20 Series TIG Torches (2-Pack)

Achieve Smoother Welds with Better Visibility

Take your TIG welding performance to the next level with the 45V43 Gas Lens, designed for 1/16" (1.6mm) setups on 9 and 20 series torches. If you have been struggling with inconsistent gas coverage or difficulty seeing into tight corners, switching from a standard collet body to a gas lens is one of the most effective upgrades you can make. This 2-pack ensures you have the parts you need to keep your torch running smoothly.

Why Use a Gas Lens?
The primary benefit of the 45V43 is its ability to calm the shielding gas. Standard nozzles often let gas exit in a turbulent cloud, which can pull in atmospheric air and contaminate your weld. This gas lens uses a fine mesh screen to smooth out that flow, creating a 'laminar' stream that hugs the weld puddle. This means you get cleaner, shinier welds with less oxidation, especially on sensitive materials like stainless steel.

Reach Tight Spots
Because the gas stream is so stable, you can stick your tungsten out much farther—often up to an inch in draft-free conditions—while still maintaining excellent shielding. This extended stick-out gives you a clear line of sight to the arc and puddle, making it easier to maneuver in confined joints or awkward angles. Whether you are a professional fabricator or a serious hobbyist, this simple upgrade improves control and weld quality instantly.
