Abstract

PURPOSE: To reduce the quantity of occurrence of spatter and to obtain a sound welded joint with high quality by detecting a short circuit between a consumable electrode and base metal and limiting the polarity and a short-circuit current value between the consumable electrode and the base metal according to length of the short-circuit time.
CONSTITUTION: When the electrode is the positive electrode, after the fact that the short circuit is generated between the consumable electrode 17 and the base metal 19 and its period of time is longer than the set short-circuit time, is detected by a welding current detection circuit 11, a welding voltage detection circuit 12, a short- circuit decision circuit 13 and a time setting circuit 14, the short-circuit current value is shifted to a value lower than a set welding current value by a command of a current value instruction circuit 16. After the fact that the consumable electrode 17 is molten and cut and both arcs 18 are ignited, is detected by the welding current detection circuit 11 and the welding voltage detection circuit 12, a welding current is returned to the original current value to continue welding. In addition, when the electrode is the negative electrode, even if the short-circuit is generated, the control is carried out in a state with the polarity at the time of short-circuiting maintained by the same control as mentioned above.
