The present disclosure relates to a welding torch having a clasp (300) that couples a protective sleeve (150) to a welding torch through a strain relief (200). The protective sleeve (150) encloses a welding cable assembly. The strain relief (200) encircles a portion of the protective sleeve (150). The protective sleeve (150) is further fitted over a ball swivel that is coupled to a handle (38) of the welding torch. The clasp (300) clamps over the strain relief (200), protective sleeve (150), and ball swivel to securely couple the protective sleeve (150) to the welding torch.

A welding torch system includes a diffuser assembly that includes a locking mechanism to receive a contact tip. Additionally, the welding torch system includes the contact tip, which includes locking elements configured to interact with the locking mechanism of the diffuser assembly to secure the contact tip within the diffuser assembly. Further, the contact tip is rotated within the diffuser assembly to securely align the locking elements with the locking mechanism.

A MIG/MAG welding torch body includes a second channel, which is arranged coaxially to the central channel, and a further third channel, which is arranged coaxially to the second channel, wherein a connection is provided between the second channel and the third channel. The first channel has an orifice in the center of the receiving part, the second channel has an orifice on the lateral side of the receiving part, and the third channel has an orifice on the lateral side of the receiving part.

The invention relates to an exchangeable wearing part of an arc welding torch, said wearing part being intended to be arranged in the region of an end, provided for carrying out a welding process, of the arc welding torch, wherein the wearing part is provided with a thread on an outer lateral surface and/or on a boundary wall of a recess, an improvement in heat transfer properties and, when such components are conducting, also improved power transmission properties are intended to be achievable. To this end, the invention proposes that, in the direction of a longitudinal axis of the wearing part, a first conical portion, having the thread provided for fastening the wearing part, of the lateral surface or of the boundary wall is followed, on the same lateral surface or boundary wall, by a thread-free second conical portion of the lateral surface or of the boundary wall.

A welding torch (1) includes a cylindrical nozzle (2) in which shielding gas is flown from an opening (3b), and an electrode (4) that is a bar-shaped body projecting from the opening (3b). The shielding gas includes upper shielding gas flowing in an upper region (3u) on an upper side of a central axis (C2) of the electrode (4), and lower shielding gas flowing in a lower region (3d) on a lower side of the central axis (C2) of the electrode (4). Atmospheric pressure of the lower shielding gas is higher than atmospheric pressure of the upper shielding gas. A method of horizontal welding with this kind of welding torch is also defined.

The present invention concerns a joined connection and a joining method for welding torch components with a first metallic tubular segment and a second metallic tubular segment, which are joined to each other by plastic deformation via an interlocking connection. The problem which the invention proposes to solve is to indicate a joined connection as well as a joining method in which two metallic welding torch components can be joined without the use of thermal joining methods, yet with comparable quality. The problem is solved in that the interlocking is formed in at least two directions of the joining surface bordering one another.

A welding torch using a shielding gas includes a diffuser and an external nozzle integrated or fastened to an insulator and a welding tip fastened to the diffuser. The welding torch includes: the amplification nozzle installed as an inner nozzle part and an outer nozzle part on the upper and lower parts of gas outlets of the diffuser. The inner nozzle part is installed to be inclined on the welding tip, and the external nozzle is partially or entirely opened.

Protective gas mouthpiece for a connection device, having a base member which has an axial opening and a mouth arranged around the opening and which can be placed on a workpiece on which a connection process is intended to be carried out, wherein the opening adjacent to the mouth defines a cleaning space into which protective gas can be introduced and which, when the connection process is carried out, can be axially delimited by the workpiece which covers the opening. The protective gas is introduced into the cleaning space in such a manner that a main flow direction of the protective gas in a radial centre of the cleaning space is orientated in a substantially radial and unidirectional manner.

A welding torch includes: a cylindrical tip body extending in an axis line direction; an orifice member arranged on a radially outer side of the tip body, between which and the tip body a first ring-like space is formed; a cylindrical nozzle arranged on a radially outer side of the orifice member with an interposition of a second ring-like space and having an edge on one side in the axis line direction. The tip body has a first emission hole via which an inner space of the tip body communicates with the first ring-like space, and the orifice member has a second emission hole via which the first ring-like space communicates with the second ring-like space. The second ring-like space is substantially closed by a sealing part on another side in the axis line direction, and an outlet opening of the second emission hole is arranged close the sealing part.
