Xtrweld 57N74XL Alumina X-long Tig Cup Large Gas Lens Size 8

Product Description

The XTRWELD 57N74XL is an extra-long alumina nozzle cup designed for use with large gas lens setups on TIG welding torches. It accepts a size 8 nozzle designation and measures 0.5 inches in inside diameter. The extended cup length improves shielding gas coverage over the tungsten and weld pool, which is especially useful on open-root joints, pipe work, and applications requiring superior arc visibility. TIG welders and pipe fitters rely on this cup as a consumable replacement to maintain consistent weld quality across extended service intervals.

This cup is designed for use with 17, 18, and 26 series TIG torches. The large gas lens configuration reduces turbulence in the shielding gas flow, producing a laminar stream that extends coverage and minimizes atmospheric contamination of the weld zone. It is well suited to both shop and field TIG applications on ferrous and non-ferrous base metals where shielding integrity is critical.

Key Features

• Extra-long cup body extends shielding gas coverage beyond standard-length nozzles
• Size 8 designation with 0.5 inch inside diameter for large gas lens bodies
• Compatible with 17, 18, and 26 series TIG torches
• Alumina construction provides high-temperature resistance and electrical insulation
• Nozzle size marked on cup for quick field identification
• OEM-quality fit for drop-in replacement without modification

Compatibility

Designed for use with 17, 18, and 26 series TIG torches equipped with large gas lens hardware. These OEM-quality consumables are stated as compatible with all major brands of torch bodies in the applicable series.

Installation Notes

TIG nozzle cups are installed and serviced by welders and pipefitters as routine consumable replacements. Power down and de-energize the welding machine before swapping torch consumables. Hand-tighten the cup onto the gas lens body until seated; avoid using tools that could crack the alumina. Verify shielding gas flow rate at the regulator after installation before resuming welding.
