USER MANUAL
Torch go home after 60sec in IDLE
Description: Set this checkbox if you need to automatically rise torch in zero position after 60sec
in the IDLE mode.
Automatic Collision Avoidance
This safety feature allows the control to automatically adjust the torch height during a cut to
help prevent torch crashes. If automatic collision avoidance is enabled, the torch will move up
any time when contact is sensed between the torch and the plate. If the torch contacts the plate
the torch will retracts while ohmic contact will lose, provided that the Use Ohmic function is
enabled.
Allowed modes on collision are “Move torch up until ohmic contact is lost” and “Stop Cutting”.
Uncheck both checkboxes to disable ACA future.
Using Ohmic on the water table.
This menu allows to enable/disable preflow in IHS if using ohmic contact sensor on the water
table.
If you keep the water low enough so it does not splash mass quantities on the torch, then
ohmic will work fine with a water table. If water gets on the surface of the material, expect the
ohmic sensor to sense the surface of the water, not the metal. If water gets back inside the torch,
often it will cause a false sense as well as it shorts from the shield to the nozzle internally. The
water in a water table becomes full of suspended solids of the metal you are cutting which raises
the conductivity of the water.
Enable the “Preflow in IHS” mode to activate the torch preflow before sensing the material and
to make the ohmic function work better with high water levels. These blows water out of the
torch and keeps water away from the sensing area. If “Preflow in HIS” is enabled, controller make
a short start push of the plasma unit on short time (0.05 - 10 sec). Usually 0.05 second value is
fine – it’s enabled air flow, but the cutter does not have time to initiate a main arc.
Arc Voltage Converter Tuning
This future allows to tune the measured arc voltage.
As a rule, on each individual plasma cutting system, the real arc voltage with the same cut
settings will differ from the value recommended by the manufacturer. It depends from the design
of the table, the length of the power cable and etc. So that the value of the measured arc voltage
to be equal to recommended by the manufacturer, it is necessary to determine the correction
factor k. To do this, follow these steps:
1. Turn off automatic control – AVC button on the Neuron panel in UCCNC.
2. Put a flat plate on the table.
3. Set the cutting height, pierce height and pierce time recommended by the manufacturer
for the metal thickness used.
4. Create a straight line cut program with a length of 100 or 200 mm, set the cut speed
recommended by the manufacturer.
5. Go to the Plotting tab of the Neuron settings and set checkbox “Allow Plotting”. Plugin will
plot a graph of the cut.
6. Start the cut.
7. After the end of the cut go to the “Plotting” tab and find real arc value on the start of the
cut. For example, on the next picture real arc voltage was 81.5 volts on the 1.5 mm cut
height.
