Hi
I currently operate a hpr 260 with an auto gas console and edge 2 controller. Just recently there is an issure with cut quality when cutting at 80A and 130A. When cutting 12mm plate at 130A the edge is not smooth. It has quite a jagged edge all the way along. All my consumables are correct and gas pressures are set as they should be. One thing i notice is that the machine does not sound as if its cutting smooth. ( i dont hear the consistent whistle that i do hear at 200A)
This makes me think that there may be a fluctuation in the cut gas. I cant seem to get to the bottom of this issue. Is there valves or anything that may need changed in the gas console? Any help would be much appreciated. Thanks.
