Fanuc likes Lincoln power supplies for arc welding , motoman use to be able to communicate to about any major arc welding power supply, the ABB's i had used miller power supplies ,
not sure what Kuka uses maybe Fronius power supplies , OTC uses their own power supplies, not sure what Nachi uses but they are similar to OTC robots
what i have seen Fanuc has come down a lot for their weld packages
i would suggest whatever brand of robot you purchase have them completely dressed out to the welding power supply - then get training from integrator on the whole system or have welding power supply vendor there to show you all
but the biggest thing is that the robot works with the power supply and have control over the weld parameters from pendent and password protected for different levels that will keep the arm engineers out of weld parameters
but yes support and how fast you can support will need to asked

i was thinking of the linear track system with robot mounted on it - either overhead or floor

there are several weld monitoring systems but most are an added feature
arc agent up in jackson mi has a system
some robots systems have arc monitoring in them - you can see on the teach pendent display
some people are using point to point distance to determine if a weld is good - really doesn't indicate the weld parameters just distance

isnt the basic plc in the robot controller - basically on the cpu main board - concurrent I/O is really what there is
most robot controllers have i/o in the main cpu board
