Abstract
A welding torch having a nozzle assembly with multiple attachment methods is disclosed. The nozzle assembly includes a nozzle shell, an electrically insulating sleeve, and a nozzle insert. The nozzle insert is configured for attachment to gas diffuser assemblies with different attachment mechanisms (e.g. a slip-on mechanism relying on frictional force, and/or screw-on mechanism relying on torque).
Claims20
A gas diffuser, comprising:
- a base comprising a groove configured to accept a retaining ring;
- a nose having gas holes;
- a core coupling the base to the nose, wherein the core includes screw threads configured to engage complementary screw threads of the nozzle assembly;
- and
- a front shoulder positioned at an intersection of the core and the base, wherein the front shoulder is configured to abut a complementary shoulder of a nozzle assembly.
