PROBLEM TO BE SOLVED: To provide a consumable electrode welding method by which dead time which a conventional consumable electrode welding method has is reduced, also an arc length after the arc is generated is properly kept, the arc in the starting end part of welding is stabilized, also the start of the arc in the next stage is satisfactorily performed by properly keeping the shape of the tip of the wire while wire sticking at the end of the arc is surely prevented. SOLUTION: Since a welding wire 1 is separated from a base material 7 and the initial arc is generated by moving a welding torch 4 in the direction in which the welding torch is separated from the base material 7 with a robot manipulator 9 while feeding the welding wire 1, reversing action is not required, the dead time is reduced, tact time is shortened and also the arc in the starting part of the welding is stabilized and "instant stop" is effectively reduced.
