Hi Sir,
I am having two ABB 6640 robots used for spot welding. I want to make that run in auto external mode. But i am not succeeding in doing that. However I have knowledge for KUKA robots for the same. Can any body please help me regarding this. My main problem is signal interfacing wiith plc and robot in external mode. Or else can any body please help me with a back up or manual of external mode so that i can get necessary support. Its urgent
