Abstract: The torch with integrated electrolytic action for the surface treatment of metals, comprises a peak-paddle (2) connected with the unipolar electric current supply (7, 16) from an external apparatus, the other pole being connected with the metal surface being treated, and has the electrolytic solution used, for the specific treatment, arranged in a tank (6, 21) connected to said torch to supply said peak-paddle through channels inside said torch; the electrolytic solution being put under pressure in the delivery direction through a dosaging device of said solution controlled by the user. Different embodiments are described with manually actuated pumps and/or rigid or flexible tanks for spraying by the user. The tank (6, 21) is advantageously made removable, to allow the replacement of the electrolytic solution and to change the type of work to be carried out on the metallic surface in a quick and clean manner.

Abstract: A machine for localized cleaning, using pickling acid or a composition/mixture of chemical elements with the effect of pickling acid, applied by mechanical feed instruments (54, 55) to the surface to be treated (5), presenting: the acid kept in a limited quantity in the work position by a cell (1; 11); the volume of this cell (7; 17) is made to match with that of the acid used, i.e. by filling it completely with acid projected on the surface to be treated; the cell having a peripheral edge (6; 23) against the aforementioned surface; the pickling acid activated by an electrode (8; 18) that activates the acid's pickling action.
