What I want to know is, are the spot welders used on robot arms typically self contained as far as the power supply requirements or do they typically have seperate power units ?
I've got one on the end of a 2000 year Nachi robot which seems to be self contained...one cable connects to the robot control box for communication with the control apparently, and another huge cable (3 wires, one of which is ground) that connects to what bascially seems to be just a large on/off breaker and huge circuit breaker.
There are at least 4 hoses coming off the spot welder...not sure if they are for air or water or both... my guess is that it may use air to close the spot welding electrodes and maybe the water is for cooling ??
