Abstract

Connection system in spark erosion machines with a pulse generator, by means of which, to produce the erosion pulses, a direct current source through an electronic work switch regulated by a metronome is connected to the slit of work, characterized by a detection connection (19) regulated by the spark voltage (Uf), the spark current (If) and by the compass signal, for the generation of a signal (not) dependent by default on the ineffective pulses for erosion, by a comparison connection (20) regulated by said signal (no) and by the compass signal for the generation of a first switching signal (Usl), if the number (No) of these ineffective pulses for erosion, a certain fraction (1 - χ 1) of the number (Ni) of the pulses triggered in the same time span, or of a second switching signal (Us2), rises if the number (No) of these ineffective pulses for erosion fall below the same fraction or a certain smaller fraction (1 - χ 2) of the number (Ni) of the triggered pulses and by a correction device (24) regulated by said switching signals within the pulse generator 1, to increase the interval duration when the first switching signal (Us1) is connected and stop decreasing the interval duration between pulses when the second switching signal (Us2) is connected.
