PROBLEM TO BE SOLVED: To provide a simple, compact and highly efficient automatic welding equipment in which a welding quantity is increased and the controlling range of welding conditions is wide. SOLUTION: The highly efficient automatic welding equipment is composed of a running rail which sets a running axis so as to coincide with the direction of a welding groove, a cart for welding head which moves on the running rail, a welding torch which is supported by the cart for welding head via an adjustment mechanism for long axis of an arc in a manner that the welding torch is so controlled to be approached to and retracted from a base material to be welded, an angle adjustment mechanism around the tilt axis of the torch with which the tilt angle of the central axis of the welding torch is adjusted and set, an oscillate mechanism which supports the welding torch so that the welding torch is movable and controllable in the horizontal direction with respect to the advance direction of the welding groove, an adjustment mechanism for vertical position which supports the welding torch so that the position of the welding torch is adjusted and set in the vertical direction with respect to the face of the base material to be welded, a pair of wire feeding nozzles provided in front of and behind the advancing direction of the welding groove of the welding torch, a heating power supply which supplies a heating current to the pair of wire feeding nozzles, and a wire feeding mechanism which feeds welding wires to the wire feeding nozzles.
