PURPOSE: A welding information management module of a welding machine and a welding information management method using the same are provided to monitor welding time and arc state according to welding process, date, and period, thereby improving the precision of welding. CONSTITUTION: A welding information management module of a welding machine comprises a sensor part, a noise removal part, a signal receiving part, a digital converter, a data computing part, a data storage module, and a display part. The noise removal part rectifies a voltage signal output from the sensor part. The data computing part calculates a cut time proportional to the number of times when receiving an arc voltage less than the set value. The data storage module stores information on welding current and the arc voltage received in the sensing point of time, and the weld time, the deviation of resistance, and the cut time calculated in the data computing part. The display part selectively shows the information about the deviation of resistance and cut time.
