摘要

The present invention is directed to controlling different aspects of a welding gun using a single amplifier circuit board. A control apparatus for a welding robot comprising a welding gun which is provided at a front end of a robot arm which is driven by plural kinds of servomotors, characterized in that 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 said welding gun; and that a servo software corresponding to each of said inverters is retrieved from a memory device by discriminating kind of each of said inverters.
