Abstract

PURPOSE:To carry out a high efficiency welding and to improve welding efficiency by a wide or a narrow groove by arranging 1st and 2nd electrodes in a nozzle. CONSTITUTION:The supply of electric current to the 1st or 2nd electrodes 2, 3 is equalized in capacity. At the time of low efficiency welding such as in a small leg welding, the current is supplied only too the electrode 2 to carry out a single gas sealed arc welding. At the time of high efficiency welding such as in a large welding, the current is supplied to the electrodes 2, 3 to carry out a double gas sealed arc welding. When a narrow groove part 5 is welded, the electrodes 2, 3 are arranged in a straight line in the traveling direction of a torch and when a wide groove part 6 is welded, the electrodes 2, 3 are in parallel in the traveling direction of the torch to carry out a highly efficient welding according to the width of a groove.
