3 – Operation
Top edge rounding: There is a slight rounding along the top edge of the cut surface.
Dross
High-speed dross: A small, linear bead of molten material attaches and hardens along the bottom edge of the cut. In
addition, S-shaped lag lines are present; dross is difficult to remove and requires grinding.
Low-speed dross: A bubbly or globular accumulation of molten material attaches and hardens along the bottom edge of
the cut. In addition, vertical lag lines may be present; dross is easy to remove and flakes off in large chunks.
Top spatter: A light spatter of molten material collects on the top edges of the cut. Usually, this spatter is
inconsequential and is most common with air plasma.
