Abstract
A welding current measuring apparatus for a resistance welding machine comprises a current detector for use in measuring and detecting welding current flowing through the resistance welding machine, a memory for successively storing and holding the current values detected over the whole energizing time, and a device for specifying a desired energizing cycle interval to compute and display current values after completion of welding, wherein any energizing cycle interval is specified at will after completion of welding so that the current values or the current waveform in the specified interval can be displayed.
