OVERVIEW

Upgrade Your Torch Performance with Genuine Weldcraft Parts

Take the frustration out of TIG welding and improve your weld quality with the Weldcraft 45V42 Gas Lens. If you are currently using a standard collet body on your WP-9 or WP-20 torch, switching to a gas lens is one of the most effective upgrades you can make. This 2-pack of genuine Weldcraft lenses is designed for use with .040-inch (1.0mm) tungsten electrodes. The gas lens features a specialized mesh screen that smooths out the flow of shielding gas as it exits the ceramic cup. Instead of a turbulent, chaotic cloud of gas, you get a smooth, straight stream that blankets your weld puddle much more effectively.

Why does this matter for the everyday welder? First, it means you can stick your tungsten out further—sometimes up to an inch depending on the cup size—while still keeping the weld protected. This is a game-changer when you are trying to weld inside a corner or a pipe and can't get the nozzle close enough. Second, the improved gas coverage means less oxidation and cleaner welds, reducing the time you spend grinding or reworking parts. It also helps save money on shielding gas in some applications by utilizing the flow more efficiently.

These gas lenses are built to last and are compatible with a wide range of air-cooled and water-cooled torches, including the popular 9 and 20 series, as well as the 22, 24, and 25 micro-torches. Because they are genuine Weldcraft components, you can trust the machining and material quality to stand up to the heat and demands of industrial use. Don't let turbulence ruin your bead; equip your torch with a 45V42 gas lens and see the difference in your puddle control and bead appearance immediately.

FAQ

The 45V42 fits 9, 20, 22, 24, and 25 series TIG torches. This includes models like the WP-9 (air-cooled) and WP-20 (water-cooled).

This gas lens is designed specifically for .040" (1.0mm) diameter tungsten electrodes.

A gas lens contains a mesh screen that creates laminar gas flow, reducing turbulence and improving shielding coverage compared to the turbulent flow of a standard collet body.

Yes, the laminar flow created by the gas lens allows for a longer tungsten stick-out (extension) while maintaining adequate gas shielding, improving visibility and access.

This package contains two (2) Weldcraft 45V42 gas lenses.

Yes, gas lenses typically require compatible gas lens nozzles (alumina cups) which are often wider than standard nozzles to accommodate the lens body.

Yes, this is a genuine Weldcraft (Miller) replacement part, ensuring high quality and proper fitment.

No, the WP-17, WP-18, and WP-26 torches use the 3-series consumables (e.g., 45V24 for .040"). The 45V42 is for the smaller 2-series front end.
