PROBLEM TO BE SOLVED: To provide a system and a method where, in multiple arc welding, inductive reactance in series with each electrode is used, thus, by the short-circuit of one arc, the remaining arc does not immediately disappear. SOLUTION: The welding system uses first and second arcs between first and second electrodes, respectively, and a common workpiece, where each of the electrodes is driven by a single power source, where there is a first inductor connected in series with the first electrode and a second inductor connected in series with the second electrode and each of the inductors has sufficient inductive reactance to store enough energy to maintain an existing arc associated with one of the electrodes for a selected general time with essentially no current to the one electrode.
