| description | PROBLEM TO BE SOLVED: To provide a portable DC arc welding machine which can be returned to a normal welding by terminating a short-circuit state in an early stage when a short circuit occurs. SOLUTION: The portable DC arc welding machine having a portable DC arc welding power source for supplying the first constant current from the welding power source to a welding output terminal and supplying the second constant current larger than the first constant current in a short-circuit state comprise: detection circuits 101, CT for detecting the welding output voltage and the welding output current at the welding output terminals P, N; a control circuit 100 for forming a control signal so as to obtain the current characteristic according to the magnitude of the welding output voltage; and output circuits 110, 111 for supplying the welding current to the welding output terminals according to the control signal from the control circuit and the detected current from the detection circuits.
