Xtrweld 57N74XXL Alumina Tig Cup Xx-long Size 8

Product Description

The XTRWELD 57N74XXL is an XX-long alumina TIG welding cup designed for use with a large gas lens configuration. Sized at 8 with a 1/2 inch diameter, this nozzle directs shielding gas flow around the tungsten electrode and weld puddle during GTAW operations. The alumina construction provides heat resistance suitable for high-temperature TIG applications. The extended length offers improved shielding gas coverage in tight joints and confined weld areas, making it a practical choice for precision TIG work on pipe, tubing, and plate. The cup is marked with the nozzle size for quick field identification during torch setup.

This cup is intended for use with 17, 18, and 26 series TIG torches equipped with a large gas lens body. It suits residential and commercial welding applications including structural fabrication, pipe welding, and precision sheet metal work. The XX-long profile is particularly useful when weld access requires the tungsten to be extended further from the collet body, or when a broader gas shielding envelope is needed to protect the weld pool.

Key Features

• XX-long cup length for extended shielding gas coverage and improved weld pool protection
• Size 8 alumina nozzle with 1/2 inch inside diameter
• Designed for large gas lens torch bodies on 17, 18, and 26 series torches

Compatibility

Compatible with 17, 18, and 26 series TIG torches configured with a large gas lens body. Designed as an OEM-style replacement consumable compatible with all major brands using this torch series.

Installation Notes

TIG welding consumable replacement should be performed by a qualified welder or welding technician. Ensure the welder is fully powered down and the torch is cool before removing or installing nozzle components. Thread the cup onto the large gas lens body finger-tight, taking care not to cross-thread the alumina nozzle. Inspect the cup for cracks or chips before each use, as damaged alumina nozzles compromise shielding gas coverage and weld quality.
