Abstract: Adjustment assembly for the rotary torch head of an electrical welding gun having a torchholder (4) supporting the welding electrode (3) and a filling wire nozzle (8) at the end of a wire feed tube (9) held in a swivel holder (11) arranged on torchholder (4) so as to be swivellably adjustable about swivel spindle (10) of filler wire nozzle (8). Torchholder (4) is swivellably adjustably held on longitudinal slide (5) about its swivel spindle (7), slide (5) being adjustably guided on a cross-slide (6) parallel to the rotation axis of the torch head. For fixing the clearance of the adjusting devices, a spring can be secured between the back of the torchholder (4) and drive shaft (15) of the torch head. The spring can be formed by the wire feed tube (9), which is secured so as to be resiliently bent out between filler wire nozzle (8) and torch head drive shaft (15).
