53N58 - Weldcraft 53N58 #4 Alumina Gas Lens Cup (10-Pack)

Precision TIG Welding with Weldcraft Alumina Gas Lens Nozzles

The Weldcraft 53N58 Alumina Gas Lens Nozzle is a critical component for professional TIG welders seeking superior shielding gas coverage and weld consistency. Manufactured from high-grade alumina ceramic, this nozzle is engineered to withstand the extreme thermal cycles inherent in Tungsten Inert Gas (TIG) welding. The alumina material offers an exceptional balance of high impact resistance and thermal conductivity, ensuring the nozzle maintains its structural integrity even during prolonged welding sessions. This specific nozzle is a Size #4, featuring a 1/4-inch (6.4mm) bore, making it ideal for precision applications where a focused gas column is required to protect the weld pool from atmospheric contamination.

Designed for compatibility with the popular 9, 20, 22, 24, and 25 series TIG torches, the 53N58 is intended for use in conjunction with a gas lens collet body. Unlike standard collet bodies that can create turbulent gas flow, a gas lens system utilizes a mesh screen to organize the shielding gas into a laminar flow pattern. This laminar flow is crucial for maintaining a stable protective atmosphere around the molten puddle, significantly reducing the risk of porosity and oxidation. By pairing this #4 alumina nozzle with a gas lens, operators can achieve cleaner welds with less post-weld cleaning required.

One of the primary technical advantages of using the 53N58 gas lens nozzle is the ability to extend the tungsten electrode further past the cup edge. The coherent gas stream provided by the gas lens assembly maintains coverage over a greater distance, allowing the welder to reach into deep corners, fillets, and confined joints without sacrificing shield quality. This improved access and visibility can be the deciding factor in achieving a defect-free root pass in complex fabrications. Sold in a convenient package of 10, these nozzles ensure that industrial operations have a steady supply of high-quality consumables to maintain production uptime.

Whether you are welding stainless steel, aluminum, or exotic alloys, the consistency of your consumables plays a vital role in the final output. Weldcraft, a brand synonymous with quality in the welding industry, ensures that each 53N58 nozzle meets strict dimensional tolerances. This guarantees a secure fit on the torch head insulator and proper alignment with the tungsten, preventing gas leakage and ensuring optimal performance.
