First choice for industrial installations: The benefits of the Sonic Digital HS4 include flexible installation, easy system integration, high degree of efficiency, and compatibility with other components. The optional available PROFIBUS and PROFINET interfaces allow for easy integration it central systems and remote access. PATENTED SONOSCAN The new SonoScan determines the optimum operating frequency even more quickly and precisely. INTELLIGENT TEACH-IN Automatic determination of the optimum start frequency and control parameters of the connected transducer systems. OPTIMUM RESULTS Calculation and compensation of the frequency offset for temperature changes, also at short intervals. The high-performance Sonic Digital HS4 welding generators are the first choice for use in industrial installations. Boasting flexible installation, easy integration into control processes, as well as high efficiency and compatibility with other system components - the generators are also attractive for large plants. The generators in the HS4 range are welding specialists and offer five welding modes: Weld by Time, Weld by Remote, Weld by Energy, Weld by Pulse, Weld by Peak Power. These allow any welding process to be securely completed.
