Abstract

Machine for cutting, drilling or executing similar operations, provided with a conductive support for the work; of a movable arm that approaches said support and separates from it to contact a die and sink it through a work piece located in the support, and of means moved by driving force to actuate the arm, comprising said means a regulating element that stops the movement of the arm towards the support and reverses said movement, said machine characterized by the fact that this regulator has a circuit for a stop or hold relay that has a direct current input stage that it comprises a gas discharge lamp regulated by a grid and because said lamp is normally limited to being non-conductive by the provision of a direct current voltage source comprising practically positive series resistances, this voltage being connected through the input electrodes of the aforementioned lamp and through the conductive members of the construction site support and the arm, or that the resistance between the work support and the arm forms a voltage divider attached to the series resistors, whereby the effective DC voltage is proportional to the resistance between the arm and the support, and the Reducing the resistance below a pre-set value decreases the bias voltage to the critical level at which the lamp acquires conductive property so that the driving force means to stop the movement of the arm towards the work.
