<P>PROBLEM TO BE SOLVED: To provide a welding power supply device which can easily measure resistance values and inductance values which are used for the calculation of a tip voltage of an electrode irrespective of installation conditions. <P>SOLUTION: At switching to a measurement mode for measuring a resistance value and an inductance value up to the tip of an electrode 12 for calculating the tip voltage, a prescribed operation is performed by a combination of a torch switch 41 and a winching switch 42c provided to a torch TH and an operation remote controller 42, respectively, for a wire supply device 13, whereby switching to the measurement mode is performed separately from original corresponding operations of the operated switches 41 and 42c. That is, measurement is performed easily by the prescribed operation of the switches 41 and 42c of the torch TH and the operation remote controller 42 present in the vicinity of the electrode 12 while confirming the state of the tip of the electrode 12 during measurement, and the measurement can be performed easily even in a state the power supply device 11 is disposed while being largely separated from the electrode 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
