<P>PROBLEM TO BE SOLVED: To provide a welding power supply device capable of evaluating measured values including resistance values and inductance values used for the calculation of a tip voltage of an electrode and determining adaptability, etc. of a power cable used on a main electric path. <P>SOLUTION: In a measurement mode for measuring the total of resistance values R and the total of inductance values L up to the tip of an electrode 12 for the calculation of a tip voltage, appropriate ranges of resistance values and inductance values at each type of a power cable 14 used on the main electric path between a power supply device 11 and the electrode 12 are kept as a database in a storage device 35. Based on appropriate ranges of the resistance values and the inductance values of the cable 14 used at present, a processing unit 32 in a control device 31 decides whether the resistance values R and the inductance values L actually measured are within the appropriate ranges or not (decision of abnormal values). <P>COPYRIGHT: (C)2012,JPO&INPIT |
