Xtrweld 45V29 Tig Gas Lens Standard Medium 0.020 Inch

Product Description

The XTRWELD 45V29 is a standard medium TIG gas lens designed for use with 17, 18, and 26 series TIG torches. Gas lenses replace the standard collet body in a TIG torch setup and use a layered mesh screen to produce a laminar shielding gas flow around the tungsten electrode. This laminar flow reduces turbulence, improves shielding gas coverage, and allows the tungsten to be extended further from the cup without losing arc stability. Rated for a 0.020 inch electrode diameter, the 45V29 measures 0.62 inches in width and weighs 0.16 pounds. It is installed by licensed welders and fabricators performing GTAW work on precision or thin-material applications.

The 45V29 suits residential and light commercial welding applications where consistent shielding gas coverage is critical. It is a direct-fit consumable for 17, 18, and 26 series air-cooled and water-cooled TIG torches commonly used in pipe, sheet metal, and structural fabrication. The electrode diameter is marked directly on the body for fast identification at the torch, reducing setup errors when switching between electrode sizes on a job.

Key Features

• Designed for 0.020 inch tungsten electrode diameter
• Layered mesh internals produce laminar shielding gas flow for improved arc stability
• Compatible with 17, 18, and 26 series TIG torches
• Electrode diameter marked on body for easy field identification
• OEM-quality construction compatible with all major torch brands

Compatibility

Designed as a direct-fit replacement gas lens for 17, 18, and 26 series TIG torches. Compatible with all major torch brands using these series designations.

Installation Notes

Installation is performed by qualified welders. Before replacing the gas lens, shut off the shielding gas supply and ensure the torch is disconnected from the power source. The gas lens threads into the torch head in place of the standard collet body; use the correct collet and back cap for the electrode size being run. Verify shielding gas flow rate after installation to confirm the laminar flow pattern is established before beginning a weld.
