摘要： PROBLEM TO BE SOLVED: To reduce such defective welding as slag inclusion, undercut, etc., and to obtain the high welded quality in good repeatability by controlling the pull-up movement of a bar steel at the time of generating an arc, the position of the bar steel during the arc holding and the pushing movement of the bar steel at the time of pressing the bar steel. SOLUTION: An inserting body 11 for generating the arc is interposed between the bar steel 9 and a steel plate 10. The welding part is surrounded with powdery and granular flux 12. The welding current is supplied between the bar steel 9 and the steel plate 10 to generate the arc. A command of an arc start detector 5 is received to pull up the bar steel 9. The end surface of the bar steel 9 and the steel plate 10 are melted, and after holding the arc for specific time, the bar steel 9 is pushed down at a comparatively high speed. At the moment of bringing the molten metal on the steel plate 10 into contact with the molten metal at the end part of the bar steel 9, the welding voltage is lowered and a short circuit detected signal is outputted. The pushing speed of the bar steel 9 is changed into a comparatively low speed based on the short circuit signal to push down a prescribed amount. The welding current is stopped and the unmelted powdery and granular flux 12 and solid slag are removed.
