I have two DX-100 robots with Miller Auto-Axcess 450 welders (Two separate work cells.) We just got one of the welders repaired and they upgraded the software. Now when I look at the Arc Monitor (Sampling) page it shows the current at -1000A and the voltage as -100V. It does not change when welding. The welds look good and sound similar on both machines. I tried changing the YEW board between robots but the problem did not follow. I had the people who did the repair come in but they could find nothing wrong with the welder. I contacted Motoman but they could not find instructions for the arc monitoring on the DX-100. (They sent me the NX-100 and DX-200 instead). Any suggestion to fix this issue will be appreciated.
Eric.
