10N2M - Weldcraft 10N2M 2.0mm TIG Collet for 17/18/26 Torches

Keep Your Arc Smooth with the Right Fit

If you are running 2.0mm tungsten in your TIG rig, you need a collet that actually fits. Jamming a metric tungsten into a standard imperial collet—or trying to crank down a larger collet to make it grip—is a recipe for frustration. The Weldcraft 10N2M Collet is built specifically for 2.0mm electrodes, giving you the secure grip and consistent electrical contact you need to lay down perfect beads. This part is designed to fit the workhorse torches of the industry: the air-cooled 17 and 26 series, and the water-cooled 18 series. Whether you are in a garage or a heavy fabrication shop, if you use these common torches, this is the part you need for your metric setups.

We all know the signs of a bad collet. You tighten the back cap, but the tungsten still slides around. Or worse, the collet twists inside the body, choking off your gas flow and overheating your torch head. These issues usually happen because of poor-quality copper or incorrect sizing. Weldcraft uses high-quality copper alloy that holds its shape better under heat. This means you get more arc time and less downtime fiddling with your torch. The collet acts as the jaw of your torch; if it doesn't bite, you don't weld. This 10N2M ensures that the current transfers smoothly from the power cable to the tip of the tungsten, giving you that crisp, instant arc start every time.

Using the correct size is also about safety and equipment longevity. A loose connection inside the torch creates resistance, which creates heat where you don't want it—inside the handle. This can melt your torch head or ruin your collet body. By matching your 2.0mm tungsten with this 10N2M collet, you ensure the system runs cool and efficient. It is a small part, but it does a big job.

Installation is straightforward: drop it into the collet body, slide in your tungsten, and tighten the back cap. Remember not to over-torque it when the tungsten isn't inserted, as that can crush the collet. Keep a few of these in your kit. Consumables are cheap; ruining a weld or a torch head because you didn't have a fresh collet is expensive. Stick with genuine Weldcraft parts to keep your machine running like a champ.
