45V17 - ESAB 45V17 Gas Lens Collet Body, 1/16 in (1.6 mm) for 17/18/26 Torches

Optimize Your TIG Welding with the ESAB 45V17 Gas Lens

The ESAB 45V17 Gas Lens Collet Body is an essential upgrade for TIG welders seeking superior shielding gas coverage and improved weld quality. Designed specifically for 1/16 inch (1.6 mm) tungsten electrodes, this component fits standard 17, 18, and 26 series TIG torches. Unlike standard collet bodies that can create turbulent gas flow, the 45V17 utilizes a multi-layer fine mesh screen to straighten the gas stream into a laminar column.

This laminar flow technology provides a wider, more stable shield around the weld pool, significantly reducing the risk of atmospheric contamination and porosity. One of the primary benefits of using the 45V17 gas lens is the ability to increase tungsten stick-out. Welders can extend the electrode further past the nozzle—often up to an inch or more depending on conditions—providing excellent visibility of the arc and puddle. This is particularly advantageous when welding inside corners, fillets, or complex geometries where standard nozzles would obstruct the view.

Constructed from high-quality brass and stainless steel mesh, the ESAB 45V17 is built to withstand the thermal cycles of professional welding environments. It requires the use of compatible gas lens nozzles (typically the 54N series) and standard collets. Whether you are fabricating stainless steel exhaust systems, aluminum structures, or precision mild steel components, switching to a gas lens setup can lead to cleaner welds and less post-weld cleanup.

Key Benefits

• Enhanced Shielding: Reduces turbulence for a cleaner weld pool.
• Better Visibility: Allows for longer tungsten extension to see tight joints.
• Gas Efficiency: Can often maintain coverage at slightly lower flow rates in draft-free conditions.
