PROBLEM
Slanted cutting
Insufficient
penetration
Presence of "low
speed dross" *
Presence of "high
speed dross" **
Rounded cutting
edge
* Low speed dross is thick, globular, easy to remove. The kerf is fairly wide.
** High speed dross is thin and difficult to remove. In very vast cutting, the walls of the cut are
rather ridged.
