Xtrweld 57N75XL Alumina X-long Tig Cup Size 6 3/8 in

Product Description

The XTRWELD 57N75XL is an extra-long alumina TIG welding cup designed for use with large gas lens setups on 17, 18, and 26 series TIG torches. The extended cup length improves shielding gas coverage over the weld puddle, which is critical when welding reactive metals or working in applications that demand tighter shielding control. At size 6 with a 3/8 inch bore diameter, this cup fits a widely used range of gas lens bodies. It is manufactured to OEM quality standards and is a direct replacement for standard consumables in professional TIG welding operations.

This cup is suited for professional welders and fabricators running 17, 18, or 26 series air-cooled TIG torches. The x-long profile is commonly chosen for pipe welding, aerospace fabrication, and precision work on stainless steel, aluminum, and titanium where extended gas shielding reduces oxidation risk. The size 6 designation is clearly marked on the cup body for fast identification during consumable changes in the field or at the bench.

Key Features

• Extra-long alumina construction extends shielding gas coverage beyond a standard-length cup
• Size 6 with 3/8 inch bore diameter — clearly marked on the cup for quick identification
• Compatible with 17, 18, and 26 series TIG torches using large gas lens bodies
• OEM-quality alumina material resists heat and electrical conductivity
• Fits all major brand torch bodies of the compatible series

Compatibility

Compatible with 17, 18, and 26 series TIG torches equipped with large gas lens components. Designed as an OEM-style replacement consumable compatible with all major brands producing torches in these series.

Installation Notes

Installation is performed by licensed welders or qualified fabricators as part of routine TIG torch consumable maintenance. Before replacing the cup, shut off the shielding gas supply and ensure the torch is disconnected from the power source. Hand-tighten the cup onto the gas lens body — do not use tools to overtighten, as alumina ceramic cups are brittle and can crack under excess force. Verify proper gas flow rate after installation before resuming welding.
