This engine-driven welding machine (1) comprises: a current setting means (52) for receiving a current setting of a DC power supply made by a user and outputs the current setting as a setting signal; an output switching means (71); and a controller (4). The output switching means (71) has a function of switching an output mode between a first output mode in which outputs of a plurality of DC power supplies (2), (3) are collectively output from a predetermined welding output terminal (23), and a second output mode in which output currents from the DC power supplies (2), (3) are output from individual welding output terminals (23), (33).
