Plasma CNC Torch Height Controller. Principal of work : Plasma machines use a constant current power supply for cutting steel. While the current of the plasma cutters is constante (adjustable by operator ) the voltage changes, when the distance between the torch tip and the metal plate changes . When the distance between the torch and cutting plate gets farther, the arc voltage increases and when the torch comes close to the plate the arc voltage will decrease.The Cutting torch voltage can range from 10 to 400 volts (or more) depends of the Plasma cutter's model.The Torch Height Controller (THC) ,will constantly measure the voltage change and will keep a constant distance between the torch and cutting plate by sending a signal to the Motorized Z axis module to go up , or down. The Dani THC uses internal Voltage Divider, build by high quality components to bring the torch high voltages to a readable safe values and precision filters to protect the CPU from high-frequency interference coming from the cutting torch The THC calculate the reading values and converting to a control signal for motorized "Z" axis ,Dani THC uses latest generation microcontroller (Atmega328) with adjustable interface using 2 friendly buttons ,3 LEDs corresponding to the output signals(Ark ON, UP,and DOWN),3 digits 7 segment led display(solit and high frequency resistable). Dani THC is build with the highest quality components to ensure a safe, durable, and reliable long term operation. Anti -Dive Function Principal of work : A reduced feed rate is often used when cutting small holes or tight angles. This diminished feed rate can lead to an elevation in arc voltage, potentially causing the THC to inadvertently lower the torch into the workpiece. To avert such instances of the torch descending into the workpiece during reduced feed rates, it is advisable to deactivate the Torch Height Control (THC). For a temporary deactivation of the THC, you can utilize the Anti-dive function on the Dani THC9SUD-1 or Dani THC9SUD-2.
