Moving Pierce Time
The Moving Pierce Time parameter specifies the amount of time that the Pierce Output
remains on while piercing with motion.
Creep Time
Specifies the amount of time after piercing the part that the torch travels at creep speed.
Creep Speed is determined by a setup parameter at the Speeds setup screen and is a
percentage of the programmed cut speed. After the Creep Time is completed, the control
accelerates to full cut speed. This parameter is helpful in allowing the operator to bring
the cutting surface up to temperature and completely pierce the metal before cutting at
full speed.
Note: Depending on the performance of the plasma system, a creep time may be
required to allow for ramp up of the cut voltage after a pierce.
Primary Torch Up Time
Specifies the amount of time used for torch lift after completing each cut. This is
normally used to provide torch head clearance and return the torch to its predefined rest
position.
Primary Torch Down Time
Specifies the amount of time used to lower the torch at the beginning of each new cut.
This is usually longer than the Pierce Torch Down Time as it involves lowering the torch
from its predefined rest position.
Pierce Torch Up Time
Specifies the amount of time used for torch lift during piercing. This parameter is used to
provide distance between the torch tip and metal surface for cutting.
Pierce Torch Down Time
Specifies the amount of time used for torch lowering during piercing.
Cut Off Time
The Cut Off delay parameter species the amount of time the cut on output will remain on
at the end of a cut.
Bleedoff Time
Specifies the amount of time that the cut torch will pause to purge the oxygen at the end
of a cut segment before traversing to the next cut segment.
Igniters
When “No” is selected, this feature will turn the Preheat on between cut segments. This
is to keep the torch lit for those cutting systems that do not have automatic torch igniters.
For those cutting systems which have automatic torch igniters or that control the torch
gases outside of the control, set this parameter to “Yes”. This tells the control not to turn
on the Preheat between cut segments.
