45V64 - 45V64 Large Gas Lens Collet Body 3/32"

Get Better Welds with the 45V64 Large Gas Lens

If you are looking to take your TIG welding game to the next level, swapping out your standard collet body for a 45V64 Large Diameter Gas Lens is one of the best upgrades you can make. Designed to fit the popular 17, 18, and 26 series torches, this gas lens is built specifically for 3/32" (2.4mm) tungsten electrodes. But what makes it so special? It's all about the gas flow. Standard torch setups tend to push gas out in a chaotic, turbulent cloud. This gas lens uses a series of fine screens to smooth that gas out into a straight, steady stream—kind of like the difference between a garden hose on 'mist' versus a solid stream.

Why does that matter for you? Two main reasons: coverage and visibility. Because the gas stream is so stable, you can stick your tungsten out much further—sometimes up to an inch or more—without losing shielding gas coverage. This is a lifesaver when you are trying to weld inside a tight corner, a deep V-groove, or a roll cage cluster where a standard cup just gets in the way. You can finally see the puddle clearly without dipping your tungsten. Plus, the better gas coverage means your welds will come out cleaner, with less oxidation and those colorful 'rainbow' beads everyone aims for on stainless steel.

This 45V64 lens is made from heavy-duty copper and brass, so it stands up to the heat of daily welding. It works with both air-cooled and water-cooled rigs. Just remember, because this is the "Large" version, you will need the matching large alumina cups (like the 57N series) and the correct insulator gasket to make it fit your torch. Once you switch to a gas lens, you likely won't ever want to go back to a standard collet body. It saves gas, improves your weld appearance, and makes the actual welding process more forgiving.
