<p>PROBLEM TO BE SOLVED: To obtain an output control apparatus of engine generator performing output control of a generator for welding. SOLUTION: The output control apparatus of an engine driven generator for welding where DC power obtained by rectifying the output from a generator G for welding is controlled according to a regulation value comprises a current regulating means VR, a current setting means IS, current detecting means CT, DET, means VS for setting first and second voltages as output voltages, a voltage detecting means, and a power control means performing constant power control such that the output current is decreased if an actually measured power is larger than a first set power when a regulated current is not higher than a first set level so that the actually measured power is matched with the first set power, and the output current is decreased if an actually measured power determined from the outputs of the current detecting means and the voltage detecting means is larger than a second set power calculated from the first and second set voltages when the regulation value of the current regulating means is between the first and second set current levels so that the actually measured power is matched with the second set power.</p> |
