Tests; Torch Height Control (Thc); Settings - PRITEC ACROS 80S Manual

7 . 2 Testing
NB! Make sure the table is level before you start testing.
1. Make sure the air compressor and plasma cutter are turned off .
2. Open a test file from the downloads page on our site.
3. Place a plate on the table.
4. Drive the machine to the desired position where you want to start cutting (see chapter 7.2). Make sure there
is enough space. To be on the safe side, steer towards the center of the plate so that there is at least 150
mm available on all sides.
5. "ZERO'' the X, Y and Z axis by clicking on the blue icons (the red lamp indication will turn green). ''ZERO'' is a
reference point so that the machine knows its position. You can set this anywhere you want. Make sure that
you set this point to the correct position due to the size of the workpiece to be cut out. You must prevent
the machine from cutting beyond its table limit.
6. Press the play icon. The machine will now play the G-code file.
7. If this goes without complications, continue with Chapter 9 .

9. Torch Height Control (THC)

The THC works as follows. A voltage is measured between the plus and minus poles of the plasma cutter using the
cable that you install from the control box to the plasma cutter. This voltage will change as the voltage of the arc
between the plasma head and the workpiece increases or decreases. After this has been set correctly, the THC will
respond by turning the Z axis up or down. As a result, the machine will continue to follow any bent plate so that the
plasma head does not come into contact with the workpiece. All this ensures a better cutting result.
With thicker plates it is not always necessary to use the THC because it will not warp quickly. If desired, you can then
disconnect the THC control cable from the control box, so that the THC controller does not receive any values and
will therefore not respond.

9.1 Settings

The Proma SD is set with standard factory settings. After proper connection, it can be controlled by most plasma
cutters.
When you switch on the control box, the THC display will show an "animated" "THC" message. Then a flashing
voltage value will appear for one second. The controller then undergoes an automatic calibration.
Once the controller is ready for use, three dashes will appear on the display as shown in the third image above.
