Abstract
Protection system for electric arc welding machines, of the type comprising a transformer, whose primary winding is connected to an electrical supply network, and the secondary to the welding circuit, essentially characterized by the fact that it comprises a switch of power, interposed in the power circuit of the primary of the transformer and associated with means for its actuation in closing and opening, subordinated to a control circuit comprising sensing means of the presence, in the welding or secondary circuit of the transformer, of the "chopping" short of the electrode, and sensor means of the passage of the arc current primed by said circuit, the arrangement being such that the control circuit keeps the power switch closed from the moment of said chopping until a small additional time after the extinction of the arch.
