
In general, Hypertherm recommends lower amperage processes for the
best cut-edge quality, and higher amperage processes for the best
dross-free cutting. When speed is more important than quality, you can
use a higher-amperage process. For guidance about process selection,
refer to
Table 27 – Process recommendations for cut quality, based on
metal thickness and type on page 214 and the Cut Chart Instruction
Manual (809830).

Category description Quality Speed
Category 1 Process Core
Thickness (PCT) • Best overall balance of productivity and
cut quality.
• The process is optimized for this
thickness.
• Expect cut speeds that range from
2,030 mm/min – 3,810 mm/min
(80 in/min – 150 in/min).
• Dross free, in most cases.
Very good Very good
Category 2 Greater than PCT • Good choice when edge quality is more
important than speed.
• Expect cut speeds that are slower than
2,030 mm/min (80 in/min).
• Expect Some low-speed dross possible.

Category 3 Less than PCT • Good choice when speed is more
important than edge quality.
• Expect cut speeds that are faster than
3,810 mm/min (150 in/min).
• Dross-free results in most cases.
Lower Higher
Category 4 Edge Start Only • Edge start is required.
• Thick, low-speed dross is likely.
Good Low
Category 5 Severance • This is the maximum thickness for these
processes.
• Edge start is required.
• Expect cut speeds that are slower than
250 mm/min (10 in/min).
• Cut-edge quality can be rough.
• Expect significant dross.
