45V28 - Weldcraft 45V28 5/32" TIG Gas Lens Collet Body (2-Pack)

Genuine Weldcraft Performance for 17, 18, and 26 Series Torches

When your TIG welding projects demand the highest quality and consistency, the Weldcraft 45V28 Gas Lens is the upgrade you need for your torch. This 2-pack of genuine Weldcraft parts is designed to fit the industry-standard 17, 18, and 26 series TIG torches, often referred to as the "large" or "3 series" torches. If you are running 5/32-inch (4.0mm) tungsten for thick plate aluminum or heavy steel fabrication, this gas lens is the correct collet body replacement to optimize your arc starts and shielding coverage.

The difference between a standard collet body and the 45V28 gas lens is immediately noticeable in the behavior of the gas. Standard bodies simply dump gas out of the nozzle, creating turbulence that can pull atmospheric air into the weld pool, leading to porosity or oxidation. The 45V28 features a fine mesh screen that organizes the gas into a smooth, column-like stream. This laminar flow wraps the weld puddle in a blanket of pure argon (or helium mix), drastically reducing the chance of weld defects. This is especially important when welding stainless steel, titanium, or other sensitive alloys where gas coverage is paramount.

For the welder in the field or the shop, this gas lens offers a practical advantage: access. Because the gas stream remains coherent over a longer distance, you can stick your tungsten out much further than usual. This allows you to reach into tight V-grooves, inside corners, or around obstructions while still seeing exactly where your arc is striking. No more guessing or welding blind because your cup is in the way.

This package includes two 45V28 gas lenses, providing excellent value and ensuring you aren't left stranded in the middle of a job. As a genuine Miller/Weldcraft product, you can trust the machining tolerances and material quality. Cheap aftermarket lenses often have uneven screens that cause erratic gas flow, but Weldcraft ensures every lens performs to spec. Pair this with a 54N series alumina cup and a 10N25 collet to complete your high-performance front-end setup.
