10N25 - Weldcraft 10N25 Collet, 1/8" (3.2mm) for 17/18/26 Torches

Reliable 1/8" Collet for Your TIG Rig

Every TIG welder knows the frustration of a slipping tungsten or a sputtering arc. Often, the culprit is a worn-out collet. The Weldcraft 10N25 Collet is the standard 1/8" (3.2mm) replacement for the most common torches in the shop—the 17, 18, and 26 series. If you are running a WP-17 air-cooled torch or a heavy-duty WP-18 water-cooled setup, this is the part you need to hold that 1/8" tungsten rock steady.

Collets take a beating. They heat up, cool down, and get twisted every time you change your stickout. Over time, cheap collets twist out of shape or lose their spring, killing your contact and ruining your weld quality. Weldcraft makes these out of quality copper that holds up longer and grips tighter. It’s a small part, but it does a big job—transferring all that amperage into your electrode.

Don't let a $2 part ruin a critical weld. Keep a fresh stack of 10N25s in your kit. They fit perfectly with your standard collet bodies and gas lenses for the 3-series (17/18/26) torches. Swap them out as soon as you see signs of wear or twisting to keep your arc smooth and your focus on the puddle.
