摘要： A plasma-arc cutting machine and a method of controlling the same, wherein a rise compensation circuit (39) and a transfer compensation circuit (44) consisting of a charge/discharge capacitor and a resistor are inserted in parallel between an electrode side connection (21) and a nozzle side connection (35) and between the electrode side connection (21) and a connection (34) of the side of a material to be cut. On the connection of the side of the material to be cut, furthermore,a diode (33) is inserted between a connection point (36) of the nozzle side connection and a connection point (43) of the transfer compensation circuit. A detector (31) for current control is provided on the electrode side connection at a point more close to the electrode side than a connection point (37) of the rise compensation circuit, and a detector (32) for detecting the transfer is provided on the connection of the side of the material to be cut at a point more close to the material to be cut than the connection point (43) of the transfer compensation circuit. Further, to carry out the operation from perforation through up to cutting, provision is made of at least a plasma torch (14a) for perforation and a plasma torch (14b) for cutting. Moreover, a voltage between the electrode (14) and the material (17) to be cut is detected, or a voltage between the nozzle (15) and the material (17) to be cut is detected, and the power source is stopped when the voltage exceeds a preset value. Therefore, the prior arc transfers easily into the main arc, and the cutting is effected using a specially provided plasma torch preventing the generation of double arcing and contributing to improving cutting precision and cutting efficiency.

摘要： A welding DC power supply system suitable for consum- - able or non-consumable electrode welding, comprising a plural number of inverter units (10) adapted to convert a first direct current into an alternate current and to rectify 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 (25) 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 (120) for controlling the phases of alternate currents produced by the respective inverter units (10), or means for selectively actuating a particular inverter unit (10A, 10B) 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 welding system and method provide for generating a controlled waveform for welding power output, the waveform comprising a plurality of successive peak phases followed by a short circuit between a welding wire electrode and an advancing weld puddle. Each then present peak phase is regulated based upon at least the immediately preceding short circuit to control the short circuit that will occur following the then present peak phase. Some embodiments permit regulating at least one waveform phase based upon at least the immediately preceding short circuit to control the next short circuit that will occur, and regulating at least one short response phase based upon at least the immediately preceding short circuit to control the next short circuit that will occur.
