Speed
Typically, manual plasma cutting speeds are limited by the sever speed. This
indicates the maximum speed you will be able to move the torch along the cut while
still penetrating the work piece. However, for applications that require a cleaner cut,
it may be important to cut closer to the quality speed.
If the cut is made too quickly, significant quantities of molten metal can form dross on
the underside of the cut. While most slag formed from carbon steel will easily chip
off, it can be a nuisance. Quality speeds are selected to keep dross formation to a
minimum.

data show the maximum cutting speeds possible for the power source at
15 - 50A. Quality cut speed recommendations are also listed for steel.
Note that when the torch is used at its limits, the quality of the cut suffers.
