49V24 - Weldcraft 49V24 3/32-Inch Gas Lens for 27 Series Torches

Precision Laminar Flow for 27 Series Torches

The Weldcraft 49V24 Gas Lens is a critical component designed to enhance the performance of TIG welding operations utilizing the 27A and 27B series torches. Engineered with precision, this gas lens replaces standard collet bodies to fundamentally change how shielding gas is delivered to the weld zone. By incorporating a multi-layer mesh screen filter, the 49V24 virtually eliminates the turbulence often associated with standard nozzle setups. This transformation of the gas stream from turbulent to laminar flow ensures a coherent, columnar column of shielding gas that provides superior protection against atmospheric contaminants such as oxygen and nitrogen, which are detrimental to weld integrity.

Specifically sized for 3/32-inch (2.4mm) tungsten electrodes, this gas lens is an essential upgrade for industrial applications requiring high-quality weld deposits. The reduction in turbulence not only improves gas coverage but also allows the operator to extend the electrode significantly farther beyond the nozzle cup—often up to an inch depending on the cup size and gas flow rate. This extended stick-out capability is invaluable when welding in deep joints, corners, or restricted access areas where standard setups would fail to provide adequate shielding. The 49V24 maintains a stable arc environment even at lower gas flow rates, potentially offering cost savings on consumables over time.

Durability and fitment are paramount in the Weldcraft design. Manufactured to tight tolerances, the 49V24 ensures a secure electrical and mechanical connection within the torch head, minimizing resistance and heat buildup. It is exclusively compatible with the Weldcraft 27A and 27B torch models, which are often utilized in mechanized or specialized manual applications. By integrating this gas lens into your welding procedure specification (WPS), you ensure consistent results, reduced rework caused by porosity, and an overall improvement in the metallurgical quality of the weldment.

In summary, the Weldcraft 49V24 represents a technical enhancement to the gas delivery system of specific TIG torches. It addresses the fluid dynamics of shielding gas to provide a wider, more stable protective envelope. For fabricators and industrial MRO professionals relying on the 27 series platform, this component is indispensable for achieving code-quality welds on stainless steel, aluminum, and other reactive metals.
