45V25 - Weldcraft 45V25 1/16-inch Gas Lens for 17/18/26 Series Torches (2-Pack)

Weldcraft 45V25 Gas Lens 1/16" (1.6mm) - 2 Pack

The Weldcraft 45V25 Gas Lens is a precision-engineered TIG welding consumable designed to optimize shielding gas coverage for 1/16-inch (1.6mm) tungsten electrodes. Manufactured by Miller Electric under the Weldcraft brand, this component is essential for professionals seeking to elevate the quality of their GTAW (Gas Tungsten Arc Welding) applications. The 45V25 is specifically compatible with the popular 17, 18, and 26 series TIG torches, making it a versatile addition to any industrial welding inventory.

Unlike standard collet bodies which can produce a turbulent gas stream, the 45V25 utilizes a multi-layered fine mesh screen to rectify the flow of argon (or other shielding gases). This design creates a coherent, laminar column of gas that envelops the weld pool more effectively. The reduction in turbulence is critical for maintaining a pure weld atmosphere, free from atmospheric contaminants like oxygen and nitrogen that cause porosity and brittleness in the weld metal. This is particularly important when working with reactive metals or high-specification alloys where weld integrity is paramount.

One of the primary operational benefits of using the 45V25 gas lens is the ability to extend the tungsten electrode further beyond the nozzle cup. In standard setups, extending the tungsten too far results in a loss of shielding gas coverage. However, the stable stream provided by this gas lens allows for significantly greater stick-out. This feature provides the welder with superior visibility of the arc and puddle, and enables access to deep grooves, fillets, and confined joints that would otherwise be impossible to weld properly. This package contains two (2) genuine Weldcraft 45V25 gas lenses, ensuring you have a backup on hand for critical projects.

Key Technical Features:

• Laminar Flow Technology: Mesh screens straighten gas flow to eliminate turbulence.
• Enhanced Reach: Permits longer electrode extension for tight spaces.
• Broad Compatibility: Fits WP-17, WP-18, and WP-26 torch bodies.
• Improved Weld Quality: Better shielding reduces oxidation and rework.
