Eastwood VERSA-CUT Assembly And Operating Instructions Manual page 30

• F6 THC contains all Torch Height Controller (THC) specific settings (FIG 40). Some of these may be fine-tuned to better implement the automatic torch
height control for your application.
- THC Enable (1) / Disable (0) - Enable (1) or disable (0) the automatic torch height control.
- Dead-band voltage (0.1 - 10.0V) - Adjustment dead zone for the torch height control. If the actual arc voltage differs from the set arc voltage by more
than this number, it will automatically adjust the torch height. Typically, 1V works well.
- THC arc voltage adjust (1 - 255) - Arc voltage ratio adjustment calculation number. Do not adjust; adjusting can cause improper function.
Default is 64.
- Sensitivity (1 - 10) - Reactivity of the torch height control. Greater numbers will make the torch adjust faster but can also cause a feedback loop
here the torch is repeatedly adjusting up and down rapidly. Default is 1.
- Manual Up/Down Speed - Manual adjustment speed of the torch height. Default is 40.
- Cutting Up/Down Speed - Automatic adjustment speed of the torch height. Default is 40.
- IHS Speed - Speed of the torch when it sets the initial height. Keep at 40 for good adjustability range of the start height.
- Zero Low Enable(0)/High Enable(1) - Leave set to (1) to enable the torch height motor.
- Limit+ Low Enable(0)/High Enable(1) - Unused in this table configuration. Leave set to (0).
- Limit- Low Enable(0)/High Enable(1) - Unused in this table configuration. Leave set to (0).
• Remember to press F7 to save your changes.
