An arc welding method in which a welding wire serving as a consumable electrode is fed toward a base material, and a welding current in a pulse form alternately including a peak current and a base current smaller than the peak current is caused to flow through the welding wire and the base material to generate an arc between the welding wire and the base material to weld the base material, the arc welding method comprising the steps of: a) detecting a short-circuit between the welding wire and the base material; and b) changing a feeding speed of the welding wire from a first feeding speed to a second feeding speed on a negative side from the first feeding speed when a speed in a direction in which the welding wire is fed toward the base material is defined as positive after the short-circuit between the welding wire and the base material is detected in the step a), c) increasing the welding current after a predetermined short-circuit standby time elapses from a time point at which the short-circuit between the welding wire and the base material is detected in the step a), k) detecting opening of the short-circuit between the welding wire and the base material; and 1) returning the feeding speed of the welding wire from the second feeding speed to the first feeding speed after the opening of the short-circuit between the welding wire and the base material is detected in the step k), wherein the step b) is performed after the step c) is started, the step c) includes the steps of: d) increasing the welding current at a first rate of current increase, being predetermined, after the short-circuit standby time elapses from a time point when the short-circuit between the welding wire and the base material is detected in the step a); and e) increasing the welding current at a second rate of current increase, being lower than the first rate of current increase, after the step d), and the step b) is performed after the step e). a) detecting a short-circuit between the welding wire and the base material; and b) changing a feeding speed of the welding wire from a first feeding speed to a second feeding speed on a negative side from the first feeding speed when a speed in a direction in which the welding wire is fed toward the base material is defined as positive after the short-circuit between the welding wire and the base material is detected in the step a), c) increasing the welding current after a predetermined short-circuit standby time elapses from a time point at which the short-circuit between the welding wire and the base material is detected in the step a), k) detecting opening of the short-circuit between the welding wire and the base material; and 1) returning the feeding speed of the welding wire from the second feeding speed to the first feeding speed after the opening of the short-circuit between the welding wire and the base material is detected in the step k), wherein the step b) is performed after the step c) is started, the step c) includes the steps of: d) increasing the welding current at a first rate of current increase, being predetermined, after the short-circuit standby time elapses from a time point when the short-circuit between the welding wire and the base material is detected in the step a); and e) increasing the welding current at a second rate of current increase, being lower than the first rate of current increase, after the step d), and the step b) is performed after the step e). d) increasing the welding current at a first rate of current increase, being predetermined, after the short-circuit standby time elapses from a time point when the short-circuit between the welding wire and the base material is detected in the step a); and e) increasing the welding current at a second rate of current increase, being lower than the first rate of current increase, after the step d), and the step b) is performed after the step e).
