An equipment for electric arc welding, characterized by comprising a transformer constituted by a core of oriented magnetic sheet, a primary winding, arranged to be connected to a corresponding supply network, and a secondary winding that provides the welding current, being essential that the primary winding can move with suitably determined and controlled movements, along the central column of the core and, therefore, with respect to the secondary winding, progressively varying the transformation ratio, and consequently the current intensity of the winding welding.
