36 Operator’s Manual
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.
Arc on Feedback
Specifies whether an arc-on (also called Plasma Go, Current Sense, Arc Transferred) signal from the
plasma system to the control is used. With Arc On Feedback ON, the control waits for Cut Sense
input to activate before initiating machine motion.
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.
Dual Grid/THC
The Dual Grid parameter enables use of the Torch Height Disable output. This output is used to
disable an automatic torch height sensor or reduce the plasma current in a switchable current plasma
system when machine speed is less than Plasma Hi/Lo Speed.
Dual Grid/THC Start
If Dual Grid is ON, the start mode can be configured to start (HI) or (LOW) at ignition time. For
switchable plasma systems, this usually means that in low mode the plasma system will only deliver
50% of the maximum output power.
Partial Raise
Enabling the Partial Raise feature will execute a tool raise at the end of the cut segment within a nest
for the time specified in the Partial Up Time parameter. Full raise will be executed at the end of the
final cut segment.
Torch Down During Cut
Turning on the Torch Down During Cut feature forces the torch down output to remain on throughout
the cut process. This is advantageous for pneumatic style torch lifters that require a constant output.
Torch Down Between Cuts
Turning on the Torch Down Between Cuts feature forces the Torch Down Output to remain on while
traversing between cut segments.
