To perform the automatic reshaping of an electrode tip without enlarging a device in an indirect welding device having the electrode tip moving back and forth by a drive source toward back bars receiving a work and in a mechanism that an arbitrary one out of these back bars is freely selected in a utilizing position opposed to the electrode tip by providing a rotary body on which plural back bars have been mounted with an interval in the peripheral direction.
A tip dresser 17 is freely movably provided to a dressing position opposed to an electrode tip 7 and to a retreat position on the side of the dressing position, and a receiving member 14 for a tip dresser is mounted on a rotary body 12. At the time of reshaping a tip, by moving the tip dresser 17 to the dressing position, and by selecting the receiving member 14 in a utilizing position, it is set so that a pressing force acting on the tip dresser 17 by the push of the electrode tip 7, can be received by the receiving member 14.
