Device for producing pulses for the ignition and stabilization of an electric-arc process |
摘要 |
A control circuit for an electric arc process in which the stabilization pulses are applied across the arc electrode by the secondary winding of a transformer through a separating condenser and a spark gap. The circuit includes a further condenser bridged across this secondary winding, a noncontrollable semiconductor network connected in series with the primary of this transformer, a charging condenser connected across the primary in series with the noncontrollable conductor network, and a resistor connected in series with this charging condenser across the current supply for the discharge process.
