Abstract
An electric arc lighting device for igniting inflammable products. The device comprises a direct current supply source and an oscillating unit constituted of a first inductance and an amplifying circuit connected in parallel with the supply source. The unit is adapted to generate an oscillation at a given frequency. A second inductance is connected in series with electrodes spaced one from another and between which the electric arc is produced at the given frequency and under a voltage induced in the second inductance by the first inductance, the first and second inductances being wounded around a same core.
