Command™ THC 399
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 in the Speed Setup Screen and is a percentage of the
programmed cut speed. After this time, the control accelerates to full cut speed.
Arc Off Time
Specifies the amount of delay to allow prior to indicating a lost cut signal. This can be useful in
helping to minimize nuisance trips when traveling over previously cut paths in complex nested parts.
Stop Time
Specifies the amount of time that motion will pause at the end of a cut. This pause is advantageous
for allowing the torch to completely raise and clear cut irregularities before continuing on to the next
cut segment.
Accel Delay
The Accel Delay parameter delays the activation of the Automatic Voltage Control to allow for the
cutting table to reach a steady cutting speed. This parameter should be set as low as possible
without allowing the torch to dive excessively at the beginning of a cut.
Retract Delay Time
Specifies the time delay at the end of the cut signal will pause prior to retracting the torch.
Ignition
Enables use of the Ignition output for use in igniting the plasma torch. If your plasma system requires
a separate ignition signal, toggle Ignition to ON. If not, leave Ignition OFF.
Voltage Control
This setup parameter allows the operator to select the Command
®
THC to operate in Manual or
Automatic mode. Manual mode will disable the torch height control allowing the torch to cut at the
specified cut height and voltage. Automatic mode allows the THC to command the torch up and
down to maintain the voltage at the specified set point.
Retract Full/Partial
Selects the retract distance to be set at Full or Partial. In the Full retract mode, the torch will retract to
the Home position. In Partial retract mode, the torch will retract to the set retract distance.
Retry On Transfer Fail
The Retry On Transfer Fail feature is used to specify the number of times the control will attempt to
fire the torch in the event that the torch fails to ignite.
Transfer Time
The Transfer Time parameter specifies the amount of time used to attempt ignition of the torch. The
ignition is confirmed by the Arc Sense Input (Arc on Feedback) to the control.
