ABSTRACT:
An electrical pulse circuit is disclosed. The electrical pulse circuit is in connection with a first pair of electrodes defining a first gap between ends thereof and a second pair of electrodes defining a second gap between ends thereof. The second gap is disposed proximate to the first gap. The circuit includes a controller, a first electrical pulse source in power connection with the first pair of electrodes, and a second electrical pulse source in power connection with the second pair of electrodes. The first electrical pulse source is productive of a high voltage low current arc across the first gap in response to the controller and the second electrical pulse source is productive of a low voltage high current arc across the second gap in response to the controller and the high voltage arc.
