SCHEDULE SETTING DEVICE OF RESISTANCE WELDING MACHINE

摘要

PURPOSE:To make setting of welding schedule simple and easy by enabling setting and alteration of items of welding schedule by three kinds of keys and displaying the result of setting of each item in a series. CONSTITUTION:When a power source is turned on and a selector switch 9 is in setting side, processing is executed in a CPU1, and thereby figures displayed in a schedule number display section are flickered. Set values of the welding schedule are read out from a nonvolatile memory 5 and displayed digitally in respective display section. When alteration of schedule number is necessary, an increment key 7 or a decrement key 8 is turned on or off. When schedule number to be changed appeared on the display section, a shift key 6 is depressed. Then, a signal is taken in the CPU1 through an interface 10 and a path B, and figure of ten order of initial pressure display section is designated, and flickering is made.
