Abstract
Some examples of the present disclosure relate to apparatus, systems, and/or methods for providing a quick connect and/or disconnect for a gas diffuser and/or neck assembly, for example, in a welding system. The gas diffuser may include threaded grooves and/or protrusions configured to engage with screw threads and/or channels of the neck assembly. The screw threads, protrusions, threaded grooves, and/or channels may be configured such that the gas diffuser may be quickly connected to, and/or disconnected from, the neck assembly.
Claims22
A gas diffuser of a welding torch, comprising:
- a rear housing portion configured for connection with a neck assembly of the welding torch, the rear housing portion comprising a rear inner wall;
- a front housing portion configured for connection with a contact tip of the welding torch, the front housing portion comprising a front inner wall, the front inner wall being threadless and configured to receive the contact tip of the welding torch;
- a middle housing portion connecting the rear housing portion and front housing portion;
- a passage that extends from a rear end of the rear housing portion, through the rear housing portion, middle housing portion, and front housing portion, to a front end of the front housing portion, wherein an inner wall of the rear housing portion encircles a portion of the passage;
- and
- a threaded groove formed in or on the rear inner wall of the rear housing portion, the threaded groove configured to interface with a protrusion of the neck assembly of the welding torch to connect the gas diffuser to the neck assembly in approximately 1.5 turns or less.
