Read this safety notice before operating.
I. Notice
1、 Notice on safety:
Original copy of safety notice should be dispensed to every operator.
Do not open the controller cover without permission; otherwise, it would be out of the range of
guarantee.
Cut off the power supply in case the machine is not used for a long time.
Pay attention not to drop any dust or iron powder into the controller.
Do not pour any liquid into the controller.
Handle with care, and do not cause any damage.
Abide by the accident prevention provision and regulations.
Abide by the accident prevention provision and regulations on Oxygen cutting.
Wear the mask when performing the plasma arc cutting, for the plasma arc will generate UV-b
radiation.
2、 Notice on correct application:
Our control system is capable of anti-interfering, but it is still required that your plasma power
supply have shielding function and the plasma controller have good grounding. Otherwise, it
will bring serious result.
Please set all parameters of the controller strictly according to the user manual; otherwise, it
may lead to failure of control system or even cause serious consequences.
The controller uses the 24V DC power supply. To avoid short circuit, please pay attention to the
voltage, negative or positive electrode of power supply when installing.
Do not insert or pull out any output plug of controller while the power supply is connected;
otherwise, it will damage the inside of controller.
If the output relay is non-solid-state relay, a freewheeling diode should be connected in parallel
on relay coil. Check the applied power supply to see whether it is up to requirements, avoid
burning out the controller.
Controller lifetime has a great relationship with ambient temperature. Install a cooling fan if the
temperature in processing area is too high. The allowable ambient temperature of the controller
is between 0°C and 60°C.
Do some protection measures if the machine is used in high temperature, damp, or dusty
environment, or environment with corrosive gas.
In place with strong vibration, add a rubber anti-vibration pad to weaken the vibration.
