Final Torch Adjustment (Fig. 5-2)
18. Make a reference mark on the top and bottom of the Torch sleeve where it meets the Torch mounting
bracket.
19. Loosen the Securing screw on the Torch mounting bracket and position the torch higher in the
mounting bracket until the arc will not transfer when the START button is depressed.
20. Once reaching this position, slowly lower the torch in 1/16" (1.6 mm) increments until the arc transfers
after the START button is depressed. This should be the highest point from the workpiece that the arc will
still transfer.
Tighten the Securing screw at this position.
21. Enable the Initial Height Sensing and press the START button. Once the arc transfers and the machine
delay time has elapsed, the metal should be pierced. Press the STOP button to terminate the plasma arc.
Observe that the UP indicator lights and the torch retracts to the upper limit switch.
22. Disable the Initial Height Sensing.
Check Torch Height Control (THC) and V/C Module
23. Angle the workpiece on the work table (one end higher than the other) to check the auto height (torch
height control) mode. Position the torch at the highest point on the workpiece. Program a square cut
pattern into the controller. (See controller instruction manual.)
24. Enable the Auto Height Control for the THC.
25. Manually lower the torch to approximately .25 inches (6mm) above the workpiece.
26. Start the arc transfer from the controller.
27. When the arc transfers and the machine delay time has elapsed, the workpiece should be pierced and
machine motion will start. As the torch travels from a high point to a low point, note that the torch stand-off
distance from the workpiece should remain constant, and that the DOWN indicator lights on the DR V/C
module.
As the torch travels from a low point to a high point, note that the torch stand-off distance from the
workpiece should remain constant and that the UP indicator lights on the DR V/C module.
As the torch makes a corner cut, the machine motion speed should remain constant and the UP and
DOWN indicators do not light. Machine motion and plasma arc will automatically stop when the cut is
complete.
The system is now operational.
