For programming the machine the basic system is ESSI (ASCII code). The ESSI system is in common use in flame cutting machines CNC controlled. The CNC system makes also possible reading other format (except ESSI), e.g. according to DIN standard. It is possible to load programs from diskette of 1.44 MB or by using network external computer by using the installed network interface card.

The memory for the technological programs enables us to store a huge number of programs. The memory can be sectioned into directories and this makes locating the necessary program easier and faster.

Additional advantages of the CNC system are:
- rotation of a program of an angle given by the operator or calculated by the system,
- by-passing of contours and selected blocks in a program,
- setting the width compensation separately for the left and right side,
- possibility of scaling of the program which is being performed,
- automatic retracing to the program breakage (e.g. after replacing the nozzle),
- continuation of the interrupted program after the emergency stop or power off..

For direct control of the machine a PLC control unit is used. It is a processor module with a built-in math co-processor. This enabled us operating with floating arithmetic point numbers. As a result a good precision of controlling the machine drives is achieved For monitoring the real position there are one or two modules HSC of high speed counters used.

- possibility to check if the layout can be laid onto the sheet,
- graphical presentation of the technological program,
- tracing of torch position on the layout,
- setting the machine parameters,
- displaying the information about the current status of the machine,
- displaying of messages for operator,
- giving information about status of emergency.

Moreover, a superordinated control with visualization enables us to perform the following tasks (e.g. edition, creation, copying the technological programs or MACRO) without stopping the cutting process. As an option it is possible to connect the CAM system PROFIL. This enables us to prepare the technological programs directly on the machine. Previously it was possible only in technological offices using a special software.
The control system for flame cutting machines is a flexible system enabling us to control not only flame cutting machines, but also other machines which needs synchronizing control of two axes - e.g. machines for chamfering, or pad welding of flat parts.
