| Zusammenfassung: | The marking device according to this invention comprises:
a point (
6
) for percussing an object (
2
) to be marked,
an electromagnet (
7
) for propelling the percussion point (
6
), and
a circuit (
9
) for electrical supply of the electromagnet (
7
).
This electrical supply circuit (
9
) comprises:
a controlled switch (
12
) connected in series with the electromagnet (
7
),
means (
10, 11
) for applying, to the terminals of the electromagnet (
7
), a voltage (U
7
) greater than the nominal voltage of this electromagnet (
7
), and
a current limiter (
13
) arranged to maintain the intensity of the current (I
7
) in the electromagnet (
7
) below a predetermined threshold. |
