Automated Cutting Speeds (continued)
NOTES:
1. Kerf widths are listed as the width of the cut at the bottom of the plate.
2. Speed, kerf width, voltage and standoff data represent realistic starting points. Adjustments may be
required to obtain optimum results.
3. The copper shield cup (9-5790) is recommended for general machine cutting. When the clear-the-plate
function of a height control is required, then the short copper shield cup (9-5801) is recommended.
4. NR in chart means piercing not recommended. Drill starting hole or edge start the cut.
