Q: I am having a problem with controlling the water conductivity in my AC200. The conductivity went over 30, and after a short while it stopped my machine from cutting. I changed the DI bottle but it has not decreased the conductivity. In fact it is still going up. I then tried resin from another source and still the same problem. Do you have any suggestions? A: High conductivity means that the water is becoming more conductive and has less resistance. The job of the DI circuit is to remove the conductive ions to make it less conductive and have higher resistance. If you have the conductivity set to 20 u,S/cm, it means that the resistivity is set to 50k ohms. If conductivity is set to 10 μS/cm, it means the resistivity is set to 100k ohms.
