The invention discloses an arcing chamber mounting structure for arc discharge type handheld stud welding gun. The structure comprises an arcing chamber (1) and an arcing chamber mounting base (2), wherein external threads (11) are arranged on the outer surface of the arcing chamber (1), internal threads (21) corresponding to the external threads (11) are arranged at the joint of an inner cavity of the arcing chamber mounting base (2) and the arcing chamber (1), and the arcing chamber (1) is in threaded connection to the arcing chamber mounting base (2). According to the structure, connectionbetween the arcing chamber and the arcing chamber mounting base is machined in a threaded-fit mounting form, axial movement of matching of the arcing chamber and the arcing chamber mounting base is not generated any more, the possibility of arc discharge distance changes is reduced, a failure rate of a welding gun is reduced, the welding quality is guaranteed, compared with an original clearance fit, the machined thread f
