TIG welding torch body, TIG welding torch handle, and TIG welding torch having the TIG welding torch body and TIG welding torch handle

摘要

The present invention relates to a tungsten insert gas (TIG) welding torch body (2), a TIG welding torch handle (8), and a TIG welding torch (1). For gas-cooled and water-cooled TIG welding torches (1), to form an easily mountable pluggable connection between the TIG welding torch body (2) and the TIG welding torch handle (8), The gas conduit (10) is provided for terminating at an inlet (16) located in the side shell of the plug-in element (7), before the distal end (11) of the plug-in element (7). A central inlet (19) is provided at the end (11) of the bayonet element (7). This central inlet terminates in a return port (21) on the side shell of the plug-in element (7), shortly before the end (11) of the plug-in element (7). In the TIG welding torch handle (8), a second conduit (34) arranged coaxially with the central conduit (33) and another third conduit (35) arranged coaxially with the second conduit. Is provided. A connection (36) is provided between the second conduit (34) and the third conduit (35). The first conduit (33) has a mouth (37) in the center of the receiving part (9). The second conduit (34) also has a mouth (38) in the side shell of the receiving part (9). Furthermore, the third conduit (35) has a mouth (39) in the side shell of the receiving part (9).
