Cutting Charts
The cutting charts shown on the following pages are intended to give the
operator the best starting point to use when making a cut on a particular
material type and thickness. Small adjustments may have to be made to
achieve the best cut. Also, remember that the arc voltage must be
increased as the electrode wears in order to maintain the correct cutting
height.
