Claims

[Scope of utility model registration request]

In an engine-driven welding machine with an AC auxiliary power source that can extract a welding current and an AC auxiliary power source current and is self-excited by a field current proportional to each of the voltage component and current component of the welding output, the AC auxiliary power source A current transformer for automatic slow speed control is interposed between the output side from which the current is to be taken out and the output side of the three-phase full-wave rectifier that rectifies the DC welding output to take out the welding current. An engine-driven welding type with an AC auxiliary power source, characterized in that an engine speed control device is connected to the engine speed control device, which sets the engine rotation speed to high speed when at least one of the AC auxiliary power source currents is detected, and lowers the engine rotation speed at other times. Machine's automatic slowing device.
