When hand cutting, cutting speeds primarily depend on
the material being cut, the thickness, and how fast the
operator can comfortably and accurately follow the line.
The following charts show optimum cutting speed ranges
for most materials using a machine torch with air plasma/
air secondary and nitrogen plasma/CO2 secondary. The
data was obtained using 1/8 in (3 mm) standoff.
