Summary:PROBLEM TO BE SOLVED: To miniaturize a direct current arc welding machine by improving the efficiency of a power generator of the direct current arc welding machine driven by means of an internal combustion engine and to reduce costs by constituting a rectifier circuit of parts having small current capacitance. SOLUTION: Twenty four pieces of coils which are provided in twenty four poles of stators of a magnetic generator driven by means of an internal combustion engine are divided into two voltage feeding power generating coils A1 , A2 which are three-phase connected, five current feeding power generating coils A3 -A7 which are three-phase connected, a current feeding power generating coil A8 which is V connected and one single-phase coil L8 w. And an output of the voltage feeding power generating coils A1 , A2 and an output of the current feeding power generating coils A3 -A8 are respectively fed between output terminals t1 , t2 of a welding machine through diode bridge full-wave rectifiers Re11 , Re12 and mixing bridge full-wave rectifiers Re21 -Re26 .
