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 (42) electrode and an advancing weld puddle (148). 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.

摘要： A system (100) and method is provided. The system (100) includes a high intensity energy source to create a molten puddle (112) on a surface of a workpiece (115) and a wire feeder (150) that feeds a wire (145) to the molten puddle (112) via a contact tube (122, 125). The system (100) also includes a power supply (130, 135) that outputs a first heating current during a first mode of operation and a second heating current during a second mode of operation. The system (100) further includes a controller (195) that initiates the first mode of operation in the power supply (130, 135) to heat the wire to a desired temperature and switches the power supply from the first mode of operation to the second mode of operation to create a micro-arc. The second mode of operation provides at least one of an increased heat input to the molten puddle (112) and an increased agitation of the molten puddle (112) relative to the first mode of operation.

摘要： A power supply for welding, cutting and similar operations includes a dual two-switch forward converter. The converter has two inverter circuits coupled in parallel but controlled to provide output power in an interleaved fashion. To avoid walking of the circuits (which could result in different duty cycles and imbalance of the load sharing), control signals are determined and applied to a first of the inverter circuits, and on times of the first circuit is monitored, such as by augmenting a counter to determine the number of clock cycles the first circuit is on. The same duration is then used for commanding output from the second inverter circuit. The duty cycles of both circuits is thus ensured to be the same regardless of changes in the total output power.
摘要翻译：用于焊接，切割和类似操作的电源包括双双开关正转变换器。该转换器具有并联耦合的两个逆变器电路，但被控制以交替的方式提供输出功率。为了避免电路的走动（这可能导致不同的占空比和负载共享的不平衡），控制信号被确定并施加到第一逆变器电路，并且在第一电路的时间被监视，例如通过增加一个计数器，用于确定第一个电路的时钟周期数。然后使用相同的持续时间来指示来自第二反相器电路的输出。因此，无论总输出功率的变化如何，两个电路的占空比被确保相同。

摘要： A method and apparatus for providing welding-type power is disclosed. The system includes a power supply, a wire feeder, and a controller. The wire feed speed is reduced when the input current exceeds a value to prevent tripping circuit breakers on the power line the welder is connected to. The speed reduction is based on an average current draw exceeding a threshold. The output voltage is reduced if the input current exceeds a second threshold.
