Abstract

PURPOSE:To easily perform welding work by allowing a movable electrode to make a straight advance as it stands when receiving the supply of parts to perform welding and allowing an operator to watch the scene where the parts are welded from above. CONSTITUTION:The parts are projection nuts 26 having projections 25 and supplied from above by a part supply rod 27 and the nuts 26 are stored in a recessed part 23. When the rod 27 retreats above than a through hole 28 and then, the movable electrode 18 is moved to the right by a working cylinder 21, the nuts 26 are press-contacted with a side plate 15 and welding is completed by energizing. Afterward, when an electrode part 19 retreats to the left by the cylinder 21, the operator moves the side plate 15 while removing it from a guide pin 17 and a steel plate part 13 is taken out.
