The invention provides a power supply and an electric arc processing method. The power supply comprises a power generation circuit, an electric arc detection circuit and a driving control circuit. The arc detection circuit is used for obtaining an arc detection signal based on a first output signal of the power generation circuit and obtaining arc detection power based on the arc detection signal and a second output signal of the power generation circuit, and the change trend of the arc detection signal is opposite to the change trend of the first output signal; and the driving control circuit is used for controlling the power generation circuit to stop outputting voltage and/or current to the load when the arc detection power reaches a target power threshold so as to carry out arc extinguishing processing. According to the application, whether electric arc is generated in the system can be judged by detecting the size of the power, and the arc is extinguished in time, so that the arc extinguishing efficiency
