53N88 - Weldcraft 53N88 #10 Large Diameter Alumina Gas Lens Cup

High-Performance Gas Shielding for Industrial TIG Welding

The Weldcraft 53N88 Alumina Nozzle is a premium consumable designed for professional TIG welding applications requiring enhanced gas coverage and durability. As a #10 size nozzle with a 5/8-inch (16mm) bore, it is engineered to work exclusively with large diameter gas lens collet bodies. This configuration is essential for welding reactive metals such as titanium, stainless steel, and aluminum, where atmospheric contamination must be strictly eliminated.

Manufactured from high-grade alumina ceramic, the 53N88 offers excellent thermal shock resistance and low thermal conductivity. This ensures the nozzle maintains its structural integrity even under high-amperage applications ranging from 125 A to 500 A. The material also resists splatter adhesion, reducing downtime associated with cleaning and replacement. Its 1-7/8 inch length provides a standard profile that balances accessibility with coverage.

This nozzle is highly versatile, fitting a wide range of air-cooled and water-cooled torches, including the 9, 17, 18, 20, 26, and 27 series, provided the appropriate large gas lens setup is installed. By laminarizing the gas flow, the 53N88 allows operators to extend the tungsten electrode further than with standard cups, improving visibility and access in complex joint geometries without compromising the inert gas shield.

Key Technical Benefits

• Superior Coverage: The 5/8" orifice creates a wide gas envelope, ideal for critical code work.
• Thermal Durability: Alumina composition withstands rapid heating and cooling cycles.
• Broad Compatibility: Fits most major TIG torch series when equipped with large gas lenses.
