Six-station welding machine to weld steel brackets, with rotating board to allow the translation of the pieces. In the first station an electronic loading arm automatically loads the piece coming from a conveyor belt, in the third station the welding head proceeds to weld the bracket, in the fourth station a testing unit proceeds to test the bracket, in the fifth station a semiautomatic screwdriver proceeds to screw the handle, which must be positioned manually by the operator in its seat, in the sixth station an electronic unloading arm automatically unloads the piece, placing it on a tilter or on a conveyor belt. Thanks to the automatic loading and unloading device, the machinery has a high production capacity and is usually integrated within a high productivity line. The standard machinery is provided with adjustable handwheels to adjust all the positions of the units; possibility of making the machinery self-dimensioning, through the use of linear actuators that allow to store all the positions according to the type of product to be welded. The whole machine is managed from a touch-screen panel, with the option of storing up to 500 working procedures, in which all the positions of the units are saved. Possibility of welding the double bracket, using the rotation of the molds on which the pieces to be welded are positioned. Possibility of welding the steel on a four-station rotating board, if it is not deemed necessary to screw the handle.
