PROBLEM TO BE SOLVED: To provide an engine driven welding machine which is favorable in operability and has high reliability and reliably performs idle stop and restart. SOLUTION: The engine driven welding machine is provided in which a welding generator is driven by an engine and the engine performs an idle operation when a welding operation is stopped, the engine driven welding machine is characterized by including an engine stop signal forming circuit IT which forms a stop signal for stopping an operation of the engine when time of the idle operation exceeds a predetermined time, a direct-current power supply PS connected to an output terminal of the welding machine, a voltage detecting means VS which detects a voltage change of the output terminal, a restart condition detecting circuit RS which forms a restart signal for restarting the engine when the detected voltage by the voltage detecting means shows a predetermined change mode for starting the welding operation, and an engine control circuit EC which stops the engine in response to the stop signal, and restarts the engine in response to the restart signal.
