Category description Quality Speed
Category 1 PCT • When possible, select Category 1 for
optimal edge quality and speed, with
minimum dross.
• The process is optimal for this
thickness.
• The cuts frequently have no dross.
Very good
to excellent
Very good
Category 2 Thicker than PCT • In most conditions, it is possible to
get square cut edges with sharp top
edges.
• A darker edge color is possible with
stainless steel.
• Some dross is possible.
Good to
very good
Lower
Category 3 Thinner than PCT • Select Category 3 when speed is
more important than edge quality.
• Some dross is possible.
Lower Higher
Category 4 Edge start only • An edge start is necessary.
• A darker edge color is possible with
stainless steel.
• Thick dross is possible.
Good Low
Category 5 Severance • This is the maximum thickness for
these processes.
• An edge start is necessary.
• Cut speeds can be very slow.
• Cut-edge quality can be rough.
• It is possible to get a lot of dross.
• Thick-metal cutting techniques can be
necessary.
• There is a risk that the voltages that
are necessary for severance cutting
can prevent the system from operating
at 100% duty cycle with extended
cutting intervals.

In general, Hypertherm recommends dross-free processes. Non-ferrous
dross is not easy to remove. The plasma cutting system supplies these
non-ferrous cutting processes, but the processes that are available are
different for different gas connect consoles: Air/Air, N
