PROBLEM TO BE SOLVED: To provide a mobile engine welding machine, where a generator for welding is arranged inside a flywheel on one side of an engine and a small- sized generator for auxiliary power supply is mounted on the other side of the engine and which is small as a whole and convenient for current use for welding and other kinds of works, such as illumination. SOLUTION: The flywheel 2 functioning concurrently as a cooling fin, where a magnet for ignition coil is mounted on its outer periphery is connected to one side of the engine 1. A magnet 6 for electric power generation is installed on the inner periphery of the flywheel 2. A coil 7 for high-frequency power generation is arranged inside the flywheel 2. Welding power is supplied via a rectifier 14, and the small-sized generator 8 for auxiliary power supply is connected to the other side of the engine 1.
