All the TIG torch accessories you need to get started in one kit, including collets, collet bodies, and nozzles.

Kits with 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 are clear, so you'll be able to see what you're working on, even when space is cramped. However, these nozzles break more easily than other nozzles. Instead of threads, the collet bodies have O-rings; push the nozzle onto the collet body, and the O-ring holds it in place.

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.

Gas-saving nozzles include a gas diffuser, so they use less gas than standard nozzles but won't compromise the quality of your weld. The gas diffuser smooths the flow of shielding gas, so it 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.
