FIELD: metal processing.
SUBSTANCE: invention relates to welding head (1) for manual welding by welding arc (3) in inert gas (WIG). Head comprises heat-resistant electrode (2). Electrode (2) is installed with possibility of movement, and can also be driven by means of device (20). Electrode (2) can perform axial rotation or oscillatory movement. During welding, at unintentional contacts between electrode (2) and welded article, undesirable welding is avoided. In case of delivery of additive compound, constantly occurring tacking of liquefied additive with electrode (2) is prevented.
EFFECT: connection of movable electrode (2) with voltage source can be carried out by means of either carbon contacts or electro-conductive liquid surrounding electrode (2).
