Direct the flow of shielding gas to your weld with these nozzles. When choosing a nozzle size, consider the thickness of the material you’re welding. In general, the thicker the material, the higher the nozzle size you should use. All nozzles require a compatible collet in order to connect to your TIG torch.

Aluminum oxide ceramic nozzles are the most common nozzles. They’re more durable than borosilicate glass nozzles but can limit visibility since they aren’t clear. Use them for general purpose welding applications. Borosilicate glass nozzles are clear, so you can see what you’re working on even in tight corners, but they break more easily than other nozzles. These nozzles require a push-on collet body.

Nozzles for narrow gas coverage are good for welding most metals. Nozzles for wide gas coverage produce a large cloud of shielding gas, so they’re a good choice when working with metals that are difficult to weld, such as titanium and Inconel. However, they’re harder to fit into corners than standard nozzles.

Gas-saving nozzles use less gas than standard nozzles but won’t compromise the quality of your weld. These nozzles require a gas diffuser, which prevents oxidation and pitting in the weld by reducing gas turbulence and improving shielding.
