An apparatus for impact marking comprises a marking unit (2) able to be gripped manually, an electronic control unit (3) mounted directly on the marking unit (2) and a power supply unit (4) situated in a transportable auxiliary containment structure (4a) and connected to the marking unit by means of an extensible cable (25) and an extensible hose (26). The marking unit (2) presents elements (7) for bearing onto a piece to be marked, and a punch (15) movable on two axes by means of motors (10, 13) controlled by the electronic control unit (3). The punch (15) can be actuated with vibratory motion by means of a solenoid valve (21) controlled by the electronic control unit (3), mounted directly on the punch head (14).
