Abstract
PURPOSE: The titled controller with simplified circuits, which is cheap and has the good followability to the voltage variation, by taking the input power source voltage or the voltage proportional to the output voltage of the welding power source unit, as the instruction voltage for controlling the wire feed speed, without giving the smoothing.
CONSTITUTION: The first constant-voltage passive element 13, the resistor 14, and the second constant-voltage passive element 15, are connected to the output side of the rectifier circuit 6; accordingly, the full-wave rectified sine wave, obtained at the output side of the rectifier circuit 6, is impressed on the circuit, consisting of the constant-voltage passive elements 15, 13, and resistors 14, 8. When the voltage of the split point of the resister 8 is impressed on the striking circuit 9, the lower part of the waveform of input voltage of the striking circuit 9 is cut off. As a result, by properly selecting the constant-voltage absorption value of the constant-voltage passive elements 15, 13, the input voltage of the striking circuit 9 can be varied so as to properly change the speed of wire feed motor.
