45V41 - Weldcraft 45V41 Gas Lens for 9/20 Series Torches (.020") - 2 Pack

Weldcraft 45V41 .020" Gas Lens - 2 Pack

Upgrade your TIG torch performance with the Weldcraft 45V41 Gas Lens, specifically designed for micro-TIG applications utilizing .020" (0.5 mm) tungsten. This package contains two high-quality gas lenses compatible with 9 Series and 20 Series TIG torches (WP-9, WP-20, A-125, W-250). For professional welders demanding precision and cleanliness in their welds, switching from a standard collet body to a gas lens is one of the most effective upgrades available.

Superior Shielding Gas Coverage

The core advantage of the 45V41 gas lens is its ability to produce a laminar gas flow. Unlike standard collet bodies which can create turbulent gas patterns that pull in atmospheric air, the fine mesh screens within the gas lens smooth out the argon flow. This creates a stable, column-like shield around the tungsten and the weld pool. This stability is crucial when welding reactive metals or when aesthetic appearance is paramount, as it drastically reduces the risk of porosity and oxidation.

Enhanced Visibility and Access

One of the practical benefits of the laminar flow provided by the 45V41 is the ability to increase tungsten stick-out. With a standard setup, extending the tungsten too far results in poor shielding. With this gas lens, you can extend the electrode significantly further—often up to an inch depending on cup size—while maintaining full protection. This allows the welder to see past the nozzle and into deep grooves or tight angles, ensuring proper fusion and arc control in difficult positions.

Compatibility and Durability

These gas lenses are built to withstand the thermal cycles of TIG welding while maintaining their structural integrity. They are designed to work seamlessly with standard 13N series collets and require compatible gas lens alumina cups (53N series) to function correctly. As a genuine Weldcraft product, you can trust the machining quality and material consistency, ensuring that your torch setup remains reliable shift after shift.
