    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.
    Ceramic Alumina—Ceramic alumina 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.
    Silicon Nitride Ceramic—Silicon nitride ceramic nozzles are just as durable as aluminum oxide ceramic nozzles, and they’ll work at higher temperatures. However, they also limit visibility because they aren’t clear. Use standard nozzles with a threaded collet body.
    For Narrow Gas Coverage—Nozzles for narrow gas coverage are good for welding most metals.
    Standard TIG Welding—Standard nozzles require a threaded collet body.
