Abstract

PURPOSE: To make possible the constant-voltage characteristic and the drooping characteristic to be reasonably switched, by installing the first and second primary windings and the slide terminals interlocked to above windings, in the transformer, and by making and breaking the second primary winding with the alteration switch.
CONSTITUTION: By connecting the alteration switch 13, the primary and the secondary windings are parallelly connected, and the output characteristic becomes the constant-voltage characteristic. By switching the alteration switch 13, the primary windings a', b', are disconnected, and the secondary windings c', e', and e, d, are connected in series. Accordingly, the composite output appears, being made from the voltage between the primary winding a, b, and e, d, of small leakage, and the voltage between the primary winding a, b, and c', e', of large leakage; therefore, by sliding e, e', a characteristic with regulated degree of drooping can be obtained. By thus switching the alteration switch 13, the constant-voltage characteristic and the drooping characteristic can be switched, so that the reasonable DC arc welder is realized.
