Abstract
A control apparatus for a welding robot has a welding gun which is provided at a front end of a robot arm to be driven by plural kinds of servomotors. An amplifier circuit board is provided so as to mount thereon appropriate inverters by selecting out of those corresponding to respective kinds of servomotors and an inverter for the welding gun. A servo software corresponding to each of the inverters is called out of a memory device by discriminating the kind of each of the inverters. In a method of teaching the welding robot in which the welding gun is opened and closed by a servomotor, plural kinds of opening and closing patterns of the welding gun are set in advance. An appropriate opening and closing pattern is selected out of the plural kinds of opening and closing patterns in accordance with the motion of the robot arm, and the selected pattern is made the teaching data relating to the opening and closing of the welding gun.
