Buttons
1. Pierce Height
This button lets you adjust the pierce height by turning the knob. You can press the IHS button
to see the height adjusted.
2. Pierce Delay
This button lets you adjust the pierce delay by turning the know. The THC will wait for this delay
before issuing motion signal to the CNC for starting the cutting operation.
3. Cut Height
This button lets you adjust the cut height. This is the distance the torch would move down after
pierce is complete and then the arc voltage height control kicks into action.
BUTTONS
Up / Down
This lets you JOG the Z axis during idle. The Z DRO on the LCD would update giving you the
precise location of the Z axis.
During cutting in Auto Mode this lets you dynamically adjust the Target Set Voltage.
During cutting in manual mode this lets you JOG the torch in fixed intervals of 0.5mm for each
press.
Auto / Manual
This lets you change the THC mode of operation from Manual to Auto and vice versa.
In Auto mode the THC works by maintaining the voltage by continuously adjusting the Z Axis. If
the THC does not read sufficient voltage after pierce it would not start the cut and show ARC
ERROR. Also UP/Down pressed during the cutting operation would adjust the SET voltage
dynamically and the operator would hence see the maintained height change proportionally.
