    • An arc welding system includes a welding torch, an electrode, and a power supply having a switching-type power converter connected to the torch. A parallel state-based controller is connected to the power converter and provides a waveform control signal thereto for controlling its operations. The controller generates a motion control signal for controlling movements of the electrode and/or the torch. A sensor senses welding voltage or welding current. A memory stores a welding state table comprising sequential control states, and stores a motion control system state table comprising further sequential control states. The welding waveform is defined in the welding state table. The controller controls the operations of the power converter through the waveform control signal according to the welding state table, simultaneously adjusting the motion control signal according to the motion control system state table. The controller transitions between control states according to the signal received from the sensor.
    • 电弧焊接系统包括焊炬,电极和具有连接到割炬的开关型功率转换器的电源。 并联状态控制器连接到功率转换器,并向其提供波形控制信号以控制其操作。 控制器产生用于控制电极和/或手电筒的运动的运动控制信号。 传感器检测焊接电压或焊接电流。 存储器存储包括顺序控制状态的焊接状态表,并且存储包括进一步的顺序控制状态的运动控制系统状态表。 在焊接状态表中定义焊接波形。 控制器根据焊接状态表通过波形控制信号控制功率转换器的运行,同时根据运动控制系统状态表调整运动控制信号。 控制器根据从传感器接收的信号在控制状态之间转换。
