Abstract
PURPOSE:To automatically set a desired reference value of a welding torch height by detecting the arc voltage or an arc current when the welding torch is at a desired height position and sampling and holding its detected result to set it as the reference value. CONSTITUTION:In the case of a constant current power source, and in the case of a constant voltage power source, the arc voltage from an arc voltage detector 1 and the arc current from an arc current detector 2 are given to one input terminal of a differential amplifier 3 respectively. Further, the output of the detector 1 or the detector 2 when the welding torch is at the desired height position is set as the reference value and given to the other input terminal of the differential amplifier 3. The differential amplifier 3 calculates input values of both the input terminals and gives this difference to a Y axis driving controller 4. The Y axis driving controller 4 drives a Y axis motor 5 according to the given difference and the position of the welding torch is corrected and maintained in the Y axial direction so that the difference is diminished to zero.
