초록 ▼

A control system for an electric arc welder performing a welding process between an electrode and a workpiece, which system comprises: a high speed switching type power supply with a controller operated at a switching frequency of at least about 10 kHz with an input current control signal to adjust the output current of the power supply; a first sensor sensing the actual arc voltage; a second sensor sensing the actual arc current; a first circuit for creating a power signal representing the desired real time power level at progressive times during the welding process; a second circuit for creating a function of the sensed actual voltage and the sensed actual current; and a third circuit for adjusting the current control signal in accordance with the difference between the power signal and the function of the actual voltage and current, preferably arc power.
