 . Set the **Cutting pre-off** value (in seconds). This allows to stop the cutting some fraction of a second before the machine stops moving at its working speed and may be useful to some users/operators depending on their cutting needs and machine configuration. This value can be set to 0 if not required by the user.
-. Select whether you want to accept jog while THC is activated. This allows for jog in the z-axis while THC is on in order to allow the user to lift/lower the torch manually (for example, to inspect it). This field can be set to OFF if the user does not want to be able to accidentally move the torch during the cutting process while the THC is ON.

+When this setting is turned ON, it is possible to set up a set of hard keys / buttons which will allow the operator to quickly adjust the THC position. To do this, head into ''Settings > Config > Panel/Pendant > Hardkeys'' and assign input numbers to which your controls are attached to the ''Jog: Z+'' and ''Jog: Z-'' (as well as ''Jog: Stop Z'') commands, as shown in the screenshot below:
+{{ :thc:thc-jog-001-hardkeys.png}}
+When the keys are then pressed during the cutting process, the THC position will reflect that by going up/down.
 . Select the **THC Jog speed ratio**. This is usually set to be an order of magnitude lower than the working speed, as to not move the torch erratically.

-  * THC Pre-off time. In order to prevent sudden movements due to rapid voltage changes as a cut (especially when cutting a hole) is done, THC can be turned off some time before the end of the cut and the machine will be kept at a set height until the THC system will move to the next cut.
