thats about what you would expect. However with some playing it could also be reduced. It may also depend on how difficult it is to remove. If it is just a light tap with a hammer and it's off then that's pretty good

Arc voltage settings in the manual are correct assuming you have new consumables and are cutting at exactly book specs. Many height control systems will be off a bit on the arc voltage due to calibration issues as well. Keep in mind that arc voltage is the feedback mechanism that controls height. The cut chart lists a cut height (usually .060"), and that is the all important number....so adjust arc voltage so that cut height is maintained. The voltage is meaningless as long as height is correct. Higher voltage equals higher height, lower voltage is lower height. Some height controls use a process called "Voltage Sampling" that auto calibrates the height / voltage settings before each cut....these are by far the easiest systems to set and use from a height and cut quality perspective.
