PURPOSE:To gather, preserve, and process freely large-capacity high-speed data, by providing first and second storage means for storage of input data, a means for processings of data, and a means which transmits data to a large-capacity processing device. CONSTITUTION:The welding signal from a welding machine is inputted to a waveform storage device 1, and the device 1 converts the input signal to a digital quantity, and data obtained as the result is supplied together with a clock signal for strobe to a bulk memory controller BMC 2. The controller BMC 2 stores this data in a bulk memory 3 and outputs stored data to a computer board 6. The computer board 6 stores input data in a floppy disc 9 by the control signal from a CPU 7 and executes various statistical processings on a basis of stored data, and processing results are sent to a terminal/hard copy device 11 through an interface I/F 10 for communication to obtain the hard copy and are sent to a large-capacity processing device 13 as required to analyze data in the device 13. |
