Abstract:
1. A welding parameters setting method for resistance welder control apparatus, the method comprising the steps of: connecting to data busses of both a robot controller and a welding timer via dual-port RAM; storing, in ROM of welding timer, character strings of items of welding parameters for displaying on a teaching pendant of a robot and initial reference values of said welding parameters in a same sequence and in corresponding manner; initially connecting said robot and said welding timer to each other; transferring said character strings of items and standard parameters from said welding timer to said robot to be stored in RAM of said robot when power source is turned on; displaying, on said teaching pendant, said character strings of items of said welding parameters and welding parameters values in same sequence and in a corresponding manner; arbitrarily changing, in said teaching pendant of said robot, said welding parameters values of any schedule in accordance with welding conditions of a welded article to which said schedule is to be applied; storing, in said RAM of said robot, said welding parameters values of any schedule; transferring said welding parameters values of any schedule to a RAM of said welding timer to be stored thereinto via dual-port RAM; and transferring, a weld command from said robot to said welding timer via said dual-port RAM so that said welding timer performs a welding process based on said welding parameters which have been edited by said teaching pendant of said robot and which are stored in said RAM of said welding timer.
