4.07 Cut Quality
Cut quality requirements differ depending on application. For instance, nitride build-up and bevel angle may be
major factors when the surface will be welded after cutting. Dross-free cutting is important when finish cut quality
is desired to avoid a secondary cleaning operation. Cut quality will vary on different materials and thicknesses.

Cut Surface
The condition (smooth or rough) of the face of the cut.
Bevel Angle
4. Place the RUN/SET switch to the RUN position.
The angle between the surface of the cut edge and a plane perpendicular to the surface of the plate. A perfectly
perpendicular cut would result in a 0° bevel angle.
Top-Edge Rounding
Rounding on the top edge of a cut due to wearing from the initial contact of the plasma arc on the workpiece.
