DC – (Duty Cycle) load time. The parameter specifies the time of the ten-minute
interval as a percentage (at surrounding temperature and machine temperature
40
o
C), during which the thermal protection of the machine or the circuit breaker
does not switch off the cutting process.

Parameters were measured on laboratory conditions on CNC ALFATEC
machines. Actual cutting speeds and thicknesses may vary based on different
cutting applications.
*Cutting process whereby the plasma is set to the maximum cutting current and
a good cut quality is achieved at a relatively good speed.
** Cutting process whereby the plasma is set to the current equal to 100% of
duty cycle and a good cut quality is achieved at a relatively good speed.
*** Cutting process whereby the plasma is set to the maximum cutting current
and an acceptable cut quality is achieved.
