Abstract
A method and apparatus for detecting electromagnetic noise generated by an arc and controlling a power supply that powers the arcs. In an embodiment of the invention, the apparatus includes an arc detection circuit and a power supply control circuit. The arc detection circuit includes an antenna and a single shot timer. Electromagnetic noise generated by an arc is received by the antenna and activates the single shot timer, which causes the power supply control circuit to interrupt the power supply powering the arc for a predetermined length of time. A microprocessor can be used together with, or instead of, the single shot timer.
