ABSTRACT:
A robot controller and a welding timer coupled to each other by a dual-port RAM which is connected to data busses thereof, and Initial reference values of welding parameters are stored into a ROM of welding timer in same sequence as character strings of items. When power is turned on, character strings of items and values of the parameters are stored into a RAM of a robot, and both are displayed on a teaching pendant in same sequence. In teaching pendant, values of welding parameters are arbitrarily changed, and then stored into RAM of robot, and also into a RAM of the welding timer via dual-port RAM. A weld command given from the robot to welding timer via dual-port RAM, welding timer performs a welding process on basis of welding parameters which have been edited by teaching pendant and stored in RAM of the welding timer.
