54N14L - Weldcraft 54N14L Long Gas Lens Cup #8 (10-Pack)

Precision Gas Coverage with Weldcraft 54N14L

The Miller Weldcraft 54N14L Long Alumina Gas Lens Nozzle is a critical component for professional TIG welders seeking to optimize their shielding gas application and weld accessibility. Engineered as part of the 3 Series consumable line, this nozzle is specifically designed to interface with gas lens collet bodies on 17, 18, and 26 series TIG torches. Unlike standard collet body setups which can create turbulent gas flow, the gas lens system utilizes a mesh screen to organize the shielding gas into a laminar column. This 54N14L nozzle extends that column, directing it precisely over the weld pool even at extended distances.

Fabricated from high-grade Alumina ceramic, this nozzle offers exceptional thermal shock resistance and durability in high-amperage applications. The #8 orifice size (1/2 inch) provides a broad umbrella of shielding gas, making it suitable for a wide range of material thicknesses and joint configurations. The defining feature of this specific SKU is its "Long" classification. By elongating the ceramic body, Weldcraft enables the operator to reach into restricted areas—such as acute angle fillets, pipe interiors, or complex manifold clusters—where a standard length cup would obstruct the torch head or limit visibility.

Using the 54N14L allows for significantly greater tungsten stick-out. In traditional setups, extending the tungsten too far results in porosity due to the dissipation of the gas shield. However, the laminar flow promoted by the gas lens and contained by this long nozzle maintains a coherent stream of Argon (or Helium mix) around the electrode and puddle. This reduction in turbulence not only improves weld quality by minimizing oxidation and atmospheric contamination but also reduces post-weld cleaning and rework. This 10-pack ensures that high-volume fabrication environments maintain a steady supply of these essential consumables.

Technical specifications confirm compatibility with standard industry torch bodies including the WP-17, WP-18, and WP-26, as well as their CS (Crafter Series) counterparts. It is an indispensable tool for precision fabrication in aerospace, motorsports, and sanitary piping industries where weld integrity and visual inspection are paramount.
