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. Nozzles for narrow gas coverage are good for welding most metals. 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.
