Clamping device () for clamping a non-consumable welding electrode () with an electrode holder (A) which has a receiving chamber (B) aligned in the longitudinal direction for receiving a welding electrode () which is insertable therein and at its front end has an end portion (C) which widens conically towards the forward end and can be compressed by means of a clamping heat sink (D) for holding the welding electrode (), thus producing a large-surface cooling end face (KSF) for cooling the welding electrode ().

Welding torch

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.

MIG/MAG welding torch body, TIG welding torch body, MIG/MAG welding torch handle, and MIG/MAG welding torch comprising such a MIG/MAG welding torch body and MIG/MAG welding torch handle

A tungsten inert gas welding torch body, a TIG welding torch handle, and a TIG welding torch has a gas channel terminating in front of the distal end of a plug-in element in an inlet opening arranged on the shell side of the plug-in element, and a central inlet mouth at the distal end of the plug-in element terminating in front of the distal end of the plug-in element in a return opening on the shell side at the plug-in element. The TIG welding torch handle has a second channel arranged coaxially to the central channel, and a third channel arranged coaxially to the second channel. A connection is between the second channel and the third channel. The first channel has a mouth in the center of the receiving part, and each of the second and third channels has a mouth on the shell side of the receiving part.

TIG welding torch body, TIG welding torch handle, and TIG welding torch having such a TIG welding torch body and TIG welding torch handle

A cooled welding torch () having a cooling circuit, which cooling circuit extends via a nozzle fitting receiver () into a gas nozzle (), and the gas nozzle () is attachable to the welding torch () by a defined turn, wherein the cooling circuit is routed through a redirecting element (), which redirecting element () is positioned above the nozzle fitting receiver () and may be turned together with the gas nozzle (), wherein a path of the cooling circuit is switchable by the position of the gas nozzle ().

A plug part for detachably connecting a torch neck of a gas-cooled welding torch to a socket part disposed on a hose package includes a cylindrical pipe element with a flange and with an axially extending channel for a welding wire and for a protective gas and includes a union nut which is rotatably disposed on the pipe element and which includes an inner thread for connection to a corresponding outer thread on the socket part. To produce an optimal connection between the torch neck and the hose package, a bevel is disposed on the flange of the pipe element of the plug part, and the end piece of the socket part has at least one axial slot.

Plug part and socket part for detachably connecting a tube elbow of a gas-cooled welding torch to a hose packet, and connecting device with such a plug part and socket part

The invention relates to a plug part () for detachable connecting a torch neck () of a water-cooled welding torch () to a socket part () arranged on a hose package (), having a cylindrical pipe element () with an axially running channel () for a welding wire () and a protective gas () and having at least two cooling channels () for supplying and returning a cooling fluid, and a union nut () rotatably arranged on the pipe element (), the union nut having an internal thread for connection to a mating external thread on the socket part (), the invention further relating to such a socket part (). In order to produce an optimal connection between the torch neck () and the hose package (), a flange () having at least one receiving opening for receiving a pin-like element () of the socket part () is arranged on the pipe element () of the plug part () in order to fix at least one angular position of the torch neck ().

Plug part and socket part for detachably connecting a pipe elbow of a water-cooled welding torch and connecting device

The invention relates to a wire inlet nozzle () for fastening in a coupling () of a hose package (), comprising a wire inlet element () and a fastening means () for a wire core () for guiding a welding wire (), wherein a main body is formed between the wire inlet element () and the fastening means () and a cavity () is formed in the wire inlet element (), in which cavity at least one sealing element () having an axial opening () for guiding the welding wire () is arranged. In order to prevent an escape of the protective gas in the wire inlet nozzle () in a direction opposite to the main conveying direction of the welding wire (), the main body forms a first part () of the wire inlet element (), and a second part () of the wire inlet element () can be detachably connected to the first part (), and the main body is designed as a separating plane for independently fastening the wire core () and the sealing element ().
