No Clamp Pressure - Polar 92 EMC

[Derak]

On a polar 92 EMC - Cutter . If the clamp time is reduced using the dial on the right of the control panel, is it possible that the clamp doesn't achieve the proper PSI before the knife contacts the paper. I had thought that shortening the clamp time would not effect the amount of pressure but it seems that it does. I guess the question is, is this normal?
