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.
