Hi, I have a NX100 robot that is sporadically failing to weld. It will go through all the motions, but not weld. It will give no errors or anything. So far, a simple reboot of the welder gets things back to functioning correctly. This happens on multiple programs, all of which have been written and used without fail for years. Doesn't seem to follow any pattern. It can go weeks without having the issue, or at times, 5 times within a day.
Any help or ideas would be greatly appreciated!
