0157121018 - ESAB 45V44 TIG Gas Lens Body 3/32" (2.4mm) for 17/18/26 Torches

Optimize Your TIG Welding with ESAB 45V44 Gas Lenses

The ESAB 45V44 Gas Lens is a critical upgrade for professional TIG welders seeking superior shielding gas coverage and improved weld quality. Designed specifically for use with 3/32-inch (2.4mm) tungsten electrodes, this gas lens body fits standard 17, 18, and 26 series TIG torches. Unlike standard collet bodies that can create turbulent gas flow, the 45V44 utilizes a multi-layered fine mesh screen to straighten the flow of argon, creating a laminar column of gas that envelops the weld pool more effectively.

At Josef Gas, we understand that precision is paramount in TIG welding. By switching to an ESAB gas lens, operators can significantly reduce the risk of atmospheric contamination, which is particularly important when welding sensitive materials like stainless steel, titanium, and aluminum. The laminar flow provided by the 45V44 allows the welder to extend the tungsten electrode further past the cup—often up to an inch or more—without losing gas coverage. This extended stick-out provides critical visibility when welding in tight corners, fillets, or complex geometries where a standard nozzle would obstruct the view.

Durability and fitment are guaranteed with ESAB's manufacturing standards. The component is machined from high-grade brass and copper alloys to withstand the thermal cycles of heavy-duty welding. Whether you are fabricating aerospace components, food-grade piping, or custom automotive parts, the ESAB 45V44 Gas Lens is an essential consumable that enhances process control and final weld aesthetics.
