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—These nozzles are more durable than borosilicate glass nozzles, but can limit visibility since they aren’t transparent. Use them for general purpose welding applications. Standard nozzles require a threaded collet body. Gas Coverage—Narrow nozzles are good for welding most metals.
