TIG Torch Collets


Hold your tungsten electrode in place during TIG welding with these collets. Slide them into a collet body or gas lens, and secure by screwing the back cap onto your torch.
Collets for ceramic nozzles are split into two sides. When you tighten the back cap, the sides squeeze together to grip the tungsten. These are the most common collet style, but the split is a weak area where they deform over time.
Collets for borosilicate glass nozzles have a wedge-shaped head that presses against the collet body when the back cap is tightened, holding the tungsten steady. This single-piece design is more durable than split collets.

TIG Torch Collet Bodies
Attach TIG torch nozzles to TIG torches with these collet bodies. Holes in the collet body route shielding gas to the nozzle to protect your weld from oxidation and pitting. Use them with a split or wedge collet to hold a tungsten electrode.
Collet bodies for ceramic nozzles have threads for connecting to ceramic nozzles. Collet Bodies for torch series numbers 9, 20, and 25 require a TIG torch insulator
Collet bodies for borosilicate glass nozzles have a silicone O-ring. Press the nozzle onto the collet body, and the O-ring holds it in place. All collet bodies for borosilicate glass nozzles require a TIG torch insulator
TIG Torch Accessory Kits

All the TIG torch accessories you need to get started in one kit, including collets, collet bodies, and nozzles.
Kits with Ceramic Nozzles
Ceramic nozzles are durable and economical—a good choice for most applications, although they do limit visibility, unlike glass. The nozzles thread directly onto the collet bodies.
Kits with Borosilicate Glass Nozzles
With a clear glass nozzle, you'll be able to see what you're working on, even when space is cramped. Glass nozzles are not as durable as ceramic nozzles, however. Instead of threads, the collet bodies have O-rings; push the nozzle onto the collet body, and the O-ring holds it in place.
These kits include a diffuser that smooths the flow of shielding gas, so the gas goes where you want it and isn't wasted. Shielding gas prevents oxidation and pitting, which weaken welds. Having reliable gas coverage means your electrode can stick out farther and reach into tight spots while staying inside the cloud of gas.
Narrow nozzles work well with most metals.
Wide nozzles spray a large cloud of shielding gas that helps with tough-to-weld metals, such as titanium and Inconel. Because of their size, they’re harder to fit into corners than standard nozzles.

Stud Welding Systems
Join threaded studs and pins to steel and stainless steel with resistance welding that won't damage the opposite side of the material.
Collets must be the same size as the stud or pin you are welding and are not interchangeable with studs from other systems.
Threaded studs are for thin-gauge base materials. 18-8 stainless steel studs are more corrosion resistant than copper-coated steel studs.
Pins are for installing insulation and acoustical lining.
