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

Device and method for welding a workpiece () having a welding torch () which can be mechanically coupled by a coupling element () to a hose bundle () for supplying the welding torch () at least with compressed air or with a protective gas, wherein compressed air applied to the coupling element () can be diverted by a diverting valve () provided in the coupling element () for actuating an actuator ().

Coupling structure and method for feeding compressed air to welding device using same

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 ().
