Abstract
A welding gun, including a contact tip assembly, a diffuser cap, a tip holder, and a shielding gas diffuser, where the shielding gas diffuser includes a casing and an axial tube extending within the casing, and where the casing and the tip holder are connected via a connection system that includes threads with reduced peaks.
Claims20
A welding gun comprising:
- a shielding gas diffuser, the shielding gas diffuser comprising,
- a casing having an outer surface and an inner surface disposed about a central axis, the inner surface comprising threads at at least one of a proximal end and a distal end of the casing, the threads of the inner surface of the casing comprising peaks with reduced high points,
- at least one axial tube extending axially within the casing, the inner surface including a directing feature to direct shielding gas within the casing into the at least one axial tube, and
- at least one radial hole formed in the outer surface of the casing, each at least one radial hole respectively extending to the at least one axial tube to transport the shielding gas out of the gas diffuser.

A welding gun comprising:
- a shielding gas diffuser, the shielding gas diffuser comprising,
- a casing having an outer surface and an inner surface disposed about a central axis, the inner surface comprising threads, where the threads are at at least one of a proximal end and a distal end of the casing, the threads having peaks where the peaks have a flattened surface,
- at least one axial tube extending axially within the casing, the inner surface including a directing feature to direct shielding gas within the casing into the at least one axial tube, and
- at least one radial hole formed in the outer surface of the casing, each at least one radial hole respectively extending to the at least one axial tube to transport the shielding gas out of the gas diffuser.
