57N74XL - Weldcraft 57N74XL #8 Extra Long Alumina Gas Lens Cup

Precision Gas Coverage for Difficult Joints

Elevate your TIG welding game with the Weldcraft 57N74XL Alumina Gas Lens Nozzle, a specialized consumable designed for the serious welder. When you are "walking the cup" or trying to lay down a perfect bead in a recessed corner, standard nozzles can limit your dexterity and obscure your view of the puddle. This extra-long nozzle changes the equation by extending the distance between the torch head and the workpiece. This added length allows you to maintain a proper torch angle even in deep grooves or tight clusters of pipe, ensuring that your tungsten stays sharp and your arc remains stable.

The 57N74XL is specifically designed for use with gas lens setups. Unlike standard collet bodies that create turbulent gas flow, a gas lens organizes the shielding gas into a laminar column. When paired with this #8 (1/2-inch) alumina cup, the result is a broad, coherent stream of argon that protects the weld pool from atmospheric contamination even at longer stick-out distances. This is critical when welding reactive metals or when the nozzle must be positioned further away from the joint due to physical obstructions. The 1/2-inch bore size is ideal for general-purpose welding, providing ample coverage for 3/32" and 1/8" tungsten electrodes.

Constructed from premium alumina, this nozzle boasts excellent dielectric strength and thermal conductivity. It effectively insulates the electrically live components of the torch from the nozzle itself, preventing arcing to the cup. The material also resists the adhesion of weld spatter, making it easier to keep clean and maintaining a smooth gas flow path. Whether you are a pipe welder, a motorsports fabricator, or an aerospace welder, the Weldcraft 57N74XL is a problem-solver that belongs in your TIG kit. It fits 17 (air-cooled), 18 (water-cooled), and 26 (air-cooled) series torches, making it a versatile addition to your arsenal.

Technical Advantages:

• Laminar Flow Support: Optimized for gas lens collet bodies to provide superior shielding.
• Thermal Shock Resistance: Handles high-amperage heat cycles without fracturing.
• Improved Visibility: The elongated shape allows for better sightlines to the tungsten tip.
• Versatile Application: Suitable for DC welding on steel/stainless and AC welding on aluminum.
