摘要： It comprises cylindrical feeder collet (6) formed with a slit portion at a front end thereof for feeding power to a welding wire internally set through; collet case (7) for storing feeder collet (6) therein, having an abutment on which the end of feeder collet (6) is abutted; flexible inner tube (4) for leading the welding wire to feeder collet (6); torch body (3) with inner tube (4) inserted therein and collet case (7) detachably disposed at the front end thereof; and spring (5) for pressurizing feeder collet (6) toward the front end of the welding wire, wherein there is provided a taper surface on at least any one of the front end of feeder collet (6) and the abutment of collet case (7). Thus, it is structurally simple and applicable for a curved torch.

摘要： If a short circuit does not occur during deceleration of a wire feed speed in forward feed of a welding wire before the wire feed speed reaches a predetermined wire feed speed, a cyclic change is stopped and the wire feed speed is constantly controlled at the first feed speed. If a short circuit occurs during forward feed at the first feed speed, deceleration from the first feed speed starts, and the cyclic change is resumed for welding. This achieves uniform weld bead without increasing spatters even if any external disturbance such as change of distance between a tip and base material occurs.

摘要： An arc welding control method for carrying out welding by generating an arc between a wire and a base material. The wire is fed at wire feed speed (Wf) of periodically repeating forward feeding and reverse feeding with predetermined frequency and amplitude from time point (100) at which start of the welding is instructed, or from a certain time point (141) after the start of the welding is instructed, and then the wire feed speed is changed to a constant speed. Since the wire feed speed is controlled by periodically repeating forward feeding and reverse feeding at the arc start, short-circuit can be opened regardless of the electromagnetic pinch force, and spatters, which are generated at the early stage of the arc start because a molten pool is not preset, can be reduced.
