Im having an issue with the touch sensing option on my ABB robot. The frustrating part is sometimes it works and sometimes it dont. I have traced all the wires to the best of my knowledge and am out of options. I am starting to believe it is on the miller side rather the ABB brains.
So i have the robot set to search the work piece and before touching i have 39V at the nozzle and Wire (Im using both), when the nozzle makes contact i have 0 volts. The issue is the 24V signal back from the Miller is apparently not coming through every time. What could be some things i could check?

I recently had a miller welder give trouble with my abb robot. I was getting arc detect at various times that there shouldn't have been. Traced it to the weld equip from teach pendant errors. Then trouble shot the miller using led lights and suggestions. Ended up being a relay on a board in the welder. Changed board and back to production. Can check it out. Follow the miller manual schematic.
