Abstract

PURPOSE:To stable a weld bead and to prevent a welding mistake by providing a controller for rotating a wire supply means normally and reversely and arranging a wire cutting device in the vicinity of the torch tip part. CONSTITUTION:The controller 8 capable of controlling the rotation normally and reversely is provided with respect to a wire feed motor 2 and the wire cutting device consisting of an air nipper 7, etc., is arranged in the vicinity of the torch 5 tip part. After the welding is finished, the wire feed motor 2 is rotated normally for a short time via the controller 8 to cut the tip part of the wire 1 by the air nipper 7. Next, the motor 2 is rotated reversely to absorb the sag of the wire 1. Since a coating of the tip of the wire 1 is removed to feed the wire, the feed of the wire is stabilized. By this method, the weld base is stabilized and welding error is perfectly prevented.
