Claims

[Claims for Utility Model Registration] A welding part is covered with gas by a welding torch placed opposite to the workpiece, an arc is generated in the gas coating, and the workpiece is welded by the heat of the arc. Welding with a welding machine. A preheating torch for heating a workpiece to be welded is provided in front of the torch in the welding direction, and a postheating torch that generates a heat input amount larger than that of the welding torch is provided at the rear of the welding torch in the welding direction. A welding machine featuring
