4T.02 Cut Quality
NOTE!
Cut quality depends heavily on setup and
parameters such as torch standoff, align-

gas pressures, and operator ability.
Cut quality requirements differ depending on applica-

may be major factors when the surface will be welded
after cutting. Dross - free cutting is important when fin-
ish cut quality is desired to avoid a secondary cleaning
operation. The following cut quality characteristics are
illustrated in the following figure:
