SF53
CNC PLASMA Torch Height Controller
Safety P-recautions
Enviroment cannot contain any explosive gas.
It must be wired by professional wiring staff. Otherwise, it may cause electronic
shock.
Cut off the power supply before wiring. Otherwise, it may cause electronic shock.
Do not touch any control port, internal boards and their electronic componets
while the electricity is turned on. Otherwise, it may cause electronic shock.

Device information

The unit is a modern analogue - microprocessor plasma torch height
controller that operates by analyzing voltage changes in the plasma source due
to variations in height between the torch tip and the material being cut. The mi-
croprocessor makes determinations to raise or lower the torch based off of the
strength of the voltage signal being read. It is equipped with an easy to read LED
display and two user friendly keys making operation simple and does not require
any additional measuring instruments. The device has patented solutions made
with the highest quality components to ensure a safe, durable, and reliable long-
term operation.

  • Page 2 SF53 http://www.aqtronic.com CNC PLASMA Torch Height Controller Terminal details: ATTENTION:When connecting directly, use the shortest possible cables for connecting the plasma source with THC controller - it is recommended the THC controller to be located directly at the plasma source.
  • Page 3 After switching power on, the THC controller’s display shows an “animated” “Aqtronic”message, and then show Limit value is presented for 1 second. When the device is ready for operation it displays “- - - “ which means it is presentthere is no input voltage.
