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 various
plasma and secondary combinations. The data was ob-
tained using the recommended 1/8 in (3 mm) standoff.
This information represents realistic expectations using
recommended practices and well maintained systems.
Actual speeds may vary up to 50% from those shown.
Factors such as parts wear, air quality, line voltage fluctua-
tions, operator experience, standoff variation and quality
of work connection may impact system performance.
