The invention relates to a concurrent electric arc pistol, having the wire feed made by means of direct current electric motor. According to the invention, the pistol comprises a body (1) on which there is threaded an air nozzle (2), mounted on a metallization head (3) wherein there are fastened some nozzle holders (4), behind the anterior face thereof, at a distance of aproximately 1 mm. By this arrangement of said nozzle holders (4) and by fastening some nozzles (6) for the wire (7) by using some nuts (5), there is achieved a slight extension of the electric arc, thereby allowing the constant feed of the wire (7) by means of a direct current motor so as to permit the mounting of the compressed-air hose (16) on the subsequent side of the pistol.
