45V33 - 1/16" Gas Lens Collet Body for 17/18/26 Series Torches

Optimize Your TIG Shielding with the ESAB 45V33 Gas Lens

The ESAB 45V33 Gas Lens Collet Body is a premium TIG welding consumable designed to replace standard collet bodies in 17, 18, and 26 series torches. Engineered for use with 1/16-inch (1.6mm) tungsten electrodes, this component (often referred to as a "Fuse & Body Assy" in legacy catalogs due to its internal diffuser screen) is essential for welders seeking superior gas coverage and weld quality.

Unlike standard collet bodies that release shielding gas in a turbulent cloud, the 45V33 utilizes a multi-layered fine mesh screen to organize the gas flow into a coherent, laminar column. This streamlined flow protects the weld pool more effectively from atmospheric contamination, which is critical when welding reactive metals like stainless steel, titanium, and aluminum. The reduction in turbulence also allows for a longer tungsten stick-out—up to an inch in some conditions—giving the operator significantly better visibility of the arc and puddle, especially when maneuvering into tight corners or deep V-grooves.

Constructed from high-quality brass and copper alloys, the 45V33 ensures excellent electrical conductivity and heat dissipation. It is designed to work in conjunction with gas lens-specific alumina nozzles (54N series), providing a complete upgrade to your standard TIG torch setup. Whether you are a precision fabricator or an industrial pipe welder, switching to a gas lens system like the 45V33 is one of the most effective ways to improve your weld consistency and appearance.
