PURPOSE: To surely carry out cleaning regardless of the outside diameter and to prevent the occurrence of uneven wear due to a teaching position error, etc., by uniformly pressing rotational cleaning brushes against the cleaning surface on the welding torch cleaning device in a welding robot, self-traveling type automatic welding equipment, etc., to perform consumable electrode welding.

CONSTITUTION: In removing spatters stuck to a power feeding part of the consumable electrode welding torch, at least a pair of rotational cleaning brushes 8a and 8b capable of sandwiching the periphery of the power feeding part are provided and an elastic member 16 which energizes these pairs of rotational cleaning brushes 8a and 8b on the peripheral surface of the power feeding part is interposed between the pair of rotational cleaning brushes 8a and 8b.
