Final Torch Adjustment
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. Slowly lower the torch in 1/16" (1.6 mm) increments until the arc transfers after the START button is
depressed. Tighten the securing screw at this position.
21. Enable the IHS system 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 illuminates and the torch retracts to the upper limit switch.
22. Disable the IHS system.
Check Torch Height Control (THC) and Digital Remote Voltage & Current Console
23. Position the workpiece on the work table with one end higher than the other end 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 (6 mm) 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 on the workpiece, note that the
torch stand-off distance from the workpiece should remain constant, and that the DOWN indicator illuminates
on the Digital Remote.
As the torch travels from a low point to a high point on the workpiece, note that the torch stand-off distance
from the workpiece should remain constant and that the UP indicator illuminates on the Digital Remote.
As the torch makes a corner cut, the machine motion speed should remain constant and the UP and DOWN
indicators do not illuminate. Machine motion and plasma arc will automatically stop when the cut is complete.
The system is now operational.
If the system does not function as outlined in this procedure, recheck the installation requirements and directions in
this manual. If all installation directives have been followed and you are still experiencing difficulty with the system,
call the Hypertherm Technical Service number listed in the front of this manual.
