32 Operator’s Manual
High Preheat
Specifies the length of time to wait at each pierce position for preheating the piece prior to piercing.
During the run-time, the operator may use the SET, EXTEND, or RELEASE softkeys to customize the
preheat length for the particular metal being cut.
Pierce Time
Specifies the amount of delay after the cutting gas is turned on before lowering the torch to the cut
position.
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.
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 light 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.
Preheat During Cut
Specifies whether the Preheat will be left on while cutting.
