<P>PROBLEM TO BE SOLVED: To provide a welding power source capable of generating a signal required when a user builds a welding device. <P>SOLUTION: The welding power source can input/output signals between itself and outer equipment through an I/O interface portion. The welding power source includes an optional output signal generating portion which generates an output signal, as for one of the above signals, to start outputting when reaching an output start time point and to end outputting when reaching an output end time point, in response to the output start time and the output end time chosen from a plurality of predefined time points in a series of welding processes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
