摘要： A welding DC power supply system suitable for consumable or non-consumable electrode welding, including plural inverter units for converting a first direct current into an alternate current and for rectifying the alternate current to produce an output of a second direct current; a circuit connecting the output of terminals of the inverter units in parallel; a detection circuit for detecting the total output current of the inverter units; and a circuit for varying the number of operating inverter units according to the value of the detected total output current. According to other aspects of the invention, the power supply system is further provided with a phase control means for controlling the phases of alternate currents produced by the respective inverter units, or means for selectively actuating a particular inverter unit or units in a short circuit period of large current in dip transfer welding, or feedback means for suppressing the current in a controlled timing in the final stage of each short circuit period to prevent spattering as caused by bursting rupture of the large short circuit current.

摘要： A method of controlling the output of a power source in consumable electrode are welding in which a short circuiting phase and an arcing phase alternately take place between a consumable electrode and a workpiece in a shielding gas atmosphere, the method being characterized by repetition of a cycle of operation consisting of: a first stage of maintaining the output welding current at a first value of a relatively low level upon establishment of a short circuit across a gap between a consumable electrode and a workpiece; a second stage of maintaining the welding current at a second value of a relatively high level succeedingly to the first stage; a third stage of lowering the welding current to a third value of a low level upon detection of necking as a premonition of rupture of short circuiting molten metal between the electrode and workpiece; a fourth stage of, upon generation of an arc across a gap between the electrode and workpiece subsequent to the third stage, maintaining the welding current at a fourth value of a relatively high level exceeding the value of average welding current; and a fifth stage of maintaining the welding current at a fifth value of a relatively low level until the gap between the electrode and workpiece is short-circuited, under control of substantially constant current characteristics to feed current of constant level irrespective of variations in arc length.
