Abstract
394,160. Supply systems for consuming - devices. KOST, H., Bergen, Upper Bavaria, Germany, Aug. 13, 1932, No. 22762. Convention date, Aug. 14, 1931. [Class 38 (iv).] In electric-arc welding, an oscillating circuit, consisting of a condenser 5 and coil 3 is placed in series with the arc 4 so that when the arc breaks oscillations are set up which ignite the arc again. The inductance 3 may have an iron core. A condenser 6 may be placed in parallel with the secondary of the supply transformer 1 to avoid the winding blocking the oscillations. A condenser 7 may be provided across the arc to smooth its action. The frequency of the circuits may be adjusted to amplify harmonics in the current from the generator 2. The winding of transformer 1 and condenser 6 may form the oscillation circuit, the condenser 5 then serving to byepass the inductance 3.
