Experience gained in restoration of a number of complicated civil engineering objects of Ukraine by the methods of the mechanized arc surfacing using a pulsed feeding mechanisms based on quasi-waved transducers with controllers of electrode wire pulsed feeding parameters, is analyzed. Long-time operation of this type of mechanisms proved their high performance and reliability. It has been revealed that the use of mobile systems, such as a semi-automatic machine with a pulsed feeding - a small-sized arc power supply source, is promising. Special designs of resonance AC arc power sources can be used as a latter for these systems.
