| Abstract: | In this peper, the authors analyse the destruction reasons of output joints in the PC controlsystem of welding process and propose corresponding protection measures. We discuss mainly occurringconditions of series resonances produced by the alternating inductive load circuit added RC protections aswell as the ill effects resulting from the resonances. Finally, it introduces some new measures to detectresonances occurring in circuits and avoid resonances. |
