摘要： A device for terminating operation of the power source of an electric arc welder for passing a current between an electrode and work piece from a first stud connected to the electrode by a first cable and a second stud connected to the work piece by a second cable to perform a welding process. The welder includes an output transformer with a known turns ratio, a primary winding and secondary winding. A first voltage sense lead is connected to the electrode and a second voltage sense lead connected to the work piece. The novel device comprises an executive program to implement a test sequence involving (a) a program routine for comparing a real time theoretical voltage, determined by the pulse waveform at a given time of the waveform, and the voltage at the sense leads at the given time; (b) a program routine to terminate operation of the power source when the theoretical voltage substantially exceeds the sense lead voltage; and, (c) a timing routine to perform the executive program at a set period.
