Abstract

PURPOSE: To achieve the smoothing of arc starting by providing an arc starting circuit which flows the electric current larger than the electric current of a superposing circuit at the arc starting and cutting off the arc starting circuit after the arc starting.
CONSTITUTION: When the contacts S1WS3 for arc starting are turned ON at the arc starting, the AC voltage of a superposing voltage transformer T2 is rectified by the rectifying diode D7 of an arc starting circuit 3 and outputs the starting electric currect by way of a starting-current-limiting resistance R2. This is 10A or more in peak value and flows together with the superposing current of a superposing circuit 2 into a tungsten electrode TD thereby heating the same until it releases thermions and letting arc be generated. When arc is started and the electric current from the main circuit 1 is output, a current-detecting relay RL is driven to turn OFF its (b) contact S4, by which the arc starting circuit is cut off.
