摘要: In a hot air hand welding device having a plastic housing (1,3,6) which forms a rod-like grip portion (1) provided with air inlet openings and in which a commutator motor (18) is secured for the drive of a blower wheel (23) that is surrounded by a section (3) of the housing (1,3,6) that adjoins the grip (1) and has a larger diameter, the blower wheel (23) is arranged adjacent to the commutator (20) of the commutator motor (18). In addition the commutator (20) as well as the carbon brushes that contact it, together with the associated brush holders (21), are arranged in the section (3) of the housing surrounding the blower wheel (23).
