Without concern for cut appearance, the fastest speed for cutting material is the maximum cut speed. For better cut angle, less dross, and cut surface
appearance, use the optimum cut speed. The values in the cut charts are basic starting points and each application may require some adjustment to
achieve the best cut characteristics.
