Abstract

PURPOSE: To make base current small, and auxiliary power source compact and inexpensive by making output voltage at the no-load of the auxiliary power source high.
CONSTITUTION: The firing time of a thyristor 9 is so adjusted with a dial 11 as to attain more than the critical current value Ic shifting to globule to be determined by the quality of base metals 7 and the diameter of a consumable electrode 4. Thence, the feed speed of the consumable electrode 4 to be determined by the thickness of the base metals 7 and the diameter of the consumable electrode 4 is adjusted with a dial 20. The dial 20 also permits adjustment of the number of pulses per unit time according to the feed speed simultaneously with the feed speed of the consumable electrode 4. The welding method is changed by changing the number of pulses per unit time without changing the firing time of the thyristor 9, according to the thickness of the base metals 7 or the feed speed of the consumable electrode 4. With this method, it does not depend upon the thicknesses of the base metals 7, the globules fixed to relatively small globule diameters drop, arc breakage is difficult to occur, hence, the base current supplied from the auxiliary power source 2 is sufficient with small current.
