OVERVIEW

Upgrade Your TIG Precision with Weldcraft Gas Lenses

Every TIG welder knows that visibility is key to a perfect bead. If you can't see the puddle clearly, you can't control it. That is where the Weldcraft 45V43 Gas Lens comes into play. Designed for the popular "2-series" torches (like the air-cooled WP-9 or the water-cooled WP-20), this gas lens is a game-changer for anyone welding with 1/16-inch tungsten. Unlike a standard collet body that simply dumps gas out of the cup, the 45V43 uses a series of fine mesh screens to smooth out the gas flow. Think of it like the aerator on your kitchen faucet—it turns a splashing, chaotic spray into a smooth, steady stream.

Why does this matter for your welds? Two main reasons: coverage and reach. The laminar flow created by this gas lens provides a much stiffer column of Argon around your weld pool. This means you get superior protection against atmospheric contamination, resulting in cleaner, shinier welds with less post-weld cleaning required. It virtually eliminates the turbulence that sucks oxygen into the puddle, which is the enemy of stainless steel and titanium welding.

The second major benefit is the ability to stick your tungsten out further. With a standard setup, extending your electrode too far results in poor gas coverage and porosity. With the Weldcraft 45V43, you can extend your tungsten significantly beyond the cup edge—sometimes up to an inch—while maintaining a perfect shield. This allows you to get into tight corners, fillet welds, and narrow gaps while still keeping the nozzle back far enough to see exactly what the arc is doing. Whether you are a hobbyist working on a manifold or a professional pipe welder, swapping to a gas lens is one of the most cost-effective upgrades you can make to your torch setup. This pack contains two genuine Weldcraft lenses, ensuring you have a backup when you need it most.

Key Benefits for the Welder:

  • Better Visibility: Extend your tungsten to see around obstructions without losing gas coverage.
  • Cleaner Welds: Laminar flow reduces oxidation and porosity.
  • Gas Savings: More efficient coverage can sometimes allow for slightly lower flow rates.
  • Versatility: Perfect for intricate work on stainless steel, chromoly, and aluminum.

FAQ

The 45V43 fits 9, 20, 22, 24, and 25 series TIG torches. These are often referred to as the '2-series' or small body torches.

This gas lens is designed specifically for 1/16 inch (1.6mm) tungsten electrodes.

Yes, you cannot use standard alumina cups with a gas lens. You must use gas lens compatible nozzles (typically the 53N series for this body size).

This product is sold as a package of 2 gas lenses.

A gas lens creates laminar gas flow, which provides better shielding coverage and allows you to extend the tungsten further out for better visibility in tight joints.

Yes, this is a genuine Weldcraft (Miller Electric) product, part number 45V43.

Yes, the 45V43 is suitable for AC TIG welding of aluminum as well as DC welding of steel and stainless, provided you are using a 1/16" electrode.

No, the gas lens replaces the collet body. You still need a standard 1/16" collet to hold the tungsten inside the gas lens.
