10N31 - Weldcraft 10N31 1/16" Collet Body (5-Pack) for 17/18/26 Torches

Keep Your Torch Running Smoothly

Every TIG welder knows the frustration of reaching for a fresh tungsten only to find their collet body is stripped, burnt, or clogged. The Weldcraft 10N31 Collet Body is the reliable workhorse you need in your kit to keep your 17, 18, or 26 series torch firing perfectly. Designed for 1/16-inch (1.6mm) tungsten, this brass collet body is the standard replacement part for the most common TIG torches in the industry. Whether you are running a heavy-duty water-cooled WP-18 or a versatile air-cooled WP-17, this part fits right in and gets the job done.

Why does the collet body matter? It’s the heart of your torch's front end. It holds the collet that grips your tungsten, and it transfers the welding current from the power cable to the electrode. If your collet body is worn out, you'll get poor contact, which leads to an unstable arc, overheating, and frustration. This Weldcraft 10N31 is built tough from solid brass to handle the heat and current of daily welding. It screws in smoothly and holds tight, giving you the confidence that your setup is solid so you can focus on laying down perfect beads.

This pack comes with five collet bodies, which is a huge plus for any serious welder. Consumables are called consumables for a reason—they eventually wear out. Having a 5-pack in your toolbox means you aren't going to be shut down in the middle of a project waiting for a $5 part to arrive in the mail. You can swap it out instantly and get back under the hood. It’s a small investment that saves you time and hassle down the road.

These are standard collet bodies, meaning they are great for general-purpose welding on steel, stainless, and aluminum. They are easy to install and work with standard ceramic cups. If you are using 1/16" tungsten for fine detail work or thin gauge materials, these are the exact bodies you need. Don't settle for cheap knock-offs that cross-thread or melt; stick with Weldcraft quality to ensure your torch performs as well as you do.
