45V116 - Weldcraft 45V116 Large Diameter Gas Lens 1/16" (2-Pack) for WP-17/18/26

Enhance Your TIG Precision with Weldcraft 45V116

Take your TIG welding performance to the next level with the Weldcraft 45V116 Large Diameter Gas Lens. Designed for the serious welder, this 2-pack of gas lenses is built to fit the popular air-cooled WP-17 and WP-26 torches, as well as the water-cooled WP-18 series. If you are running 1/16-inch (1.6mm) tungsten, swapping your standard collet body for this large gas lens is one of the most effective upgrades you can make to your torch setup.

Why Switch to a Large Gas Lens?
The magic lies in the mesh screens. Standard collet bodies often let gas exit the nozzle in a turbulent, chaotic cloud. The 45V116 organizes that gas into a smooth, laminar column. This laminar flow means you can stick your tungsten out much further—often up to an inch or more depending on the cup size—without losing shielding coverage. This extended stick-out is a game-changer when you need to see around a corner, reach into a deep V-groove, or weld inside a tight fillet where a standard nozzle would block your view.

Superior Coverage for Critical Alloys
When welding stainless steel, titanium, or Inconel, keeping oxygen away from the hot metal is paramount. The "Large Diameter" aspect of the 45V116 provides a wider umbrella of argon coverage compared to standard gas lenses. This results in cleaner welds with less discoloration and oxidation. It also allows for a more forgiving arc length, as the stable gas column is less likely to be disturbed by minor movements or ambient air currents.

Installation and Setup
To use the 45V116, ensure you have the correct setup. You will need a large diameter gas lens insulator (typically part number 54N63) and large diameter alumina cups (57N series). Once installed, you will notice a quieter arc and a more stable puddle immediately. Whether you are walking the cup on pipe or performing delicate bench work, the Weldcraft 45V116 gives you the control and visibility needed for X-ray quality welds.
