FIELD: electrical engineering. ^ SUBSTANCE: self-contained power supply contains a higher current frequency induction generator with an excitation winding, an excitation capacitor, an additional capacitor, a matching transformer, a current transformer, an adjustment component with a control circuit and current setting device, resistor and condenser reactance and welding electrodes. The excitation capacitor is connected in parallel to the excitation winding. The matching transformer primary, the additional capacitor, the adjustment element with the control circuit and current setting device are connected in series to the excitation winding. The adjustment element and additional capacitor are shunted by the resistor and condenser reactance connected in series. The matching transformer secondary is connected, via the current transformer, to welding electrodes, the said transformer output being connected to the control circuit. ^ EFFECT: expanded performances due to adjusted welding current. ^ 1 dwg |
