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.
