Title: NOZZLE AND GAS DIFFUSER ASSEMBLIES FOR WELDING TORCHES
Abstract:
A nozzle assembly for a welding torch is disclosed. The nozzle assembly (300) comprises a nozzle (348), a contact tip (356), and a gas diffuser assembly (400). The gas diffuser assembly (400) comprises a gas diffuser (500) coupled to an insulator (900). The gas diffuser is also coupled to a gooseneck (346) and the contact tip (356). The nozzle is coupled to the gas diffuser assembly, such that the contact tip is retained within the nozzle. The nozzle (348) and gas diffuser assembly (400) further include complementary engagement features to couple the nozzle to the gas diffuser assembly. The nozzle also includes a spatter deflector (328) configured to deflect or block spatter from obstructing gas holes of the gas diffuser assembly.
