Auto Kerf Detect
The Auto Kerf Detect feature reduces the possibility of the torch diving into the plate. When
enabled, the THC will detect sudden changes in arc voltage when crossing a Kerf path and will
freeze motion of the THC.
Auto Kerf Voltage Change
The Auto Kerf feature of the Sensor THC will detect a voltage change when the torch passes over
a previous cut and will disable the THC to prevent the torch from diving. This setup parameter is
used to specify the allowable variation from the voltage setpoint at which the THC will detect the
voltage change and disable the THC.
Kerf Detect Reacquire Time
The Kerf Detect Reacquire Time determines the time limit at which the control will force the THC
to adjust the THC height to meet the voltage setpoint if the Automatic Voltage Lock On has not
been established after a Kerf crossing.
Note: Depending on the performance of the plasma system being used, a creep time may be
required to allow for ramp up of the cut voltage after the pierce.
Marker Setups
