Safety Precautions
Attention
▴Before using the machine, users are required to carefully read this manual and other operating
requirements, strictly abide by the operating specifications. Professional are required for operating
the machine.
Attention
▴The machine uses class 4 laser (strong laser radiation). The laser radiation may possibly cause
the following accidents: ① emblaze the surrounded flammable materials; ② generate other
radiations and toxic or hazardous gas by processed objects during laser processing; ③ direct
irradiation of laser radiation cause harm to human body. Therefore, firefighting devices are
required in the operating place of the machine. Stacking flammable or explosive objects near the
machine is strictly prohibited. Good ventilation is a must. Only the qualified personnel are
authorized to approach the machine.
Attention
▴The processed objects and discharged materials are required to satisfy requirements as per local
laws and regulations.
Attention
Laser processing is with potential risks. Users should carefully make sure if the processed
objects are suitable for laser processing.
There is high voltage and potential risk in the laser machine. Unauthorized disassembly by
unqualified personnel is prohibited.
Reliable earthing is required for the machine and related other machine before power-on.
During operating, removing any cover of the machine is strictly prohibited.
During operating, the operators are required to observe working status of the machine all the
time. In case of any abnormality, it is immediately to disconnect power supply and take active
and corresponding measures.
After power-on, special personnel are required for monitoring. Unauthorized leaving is strictly
prohibited.
It is a must to disconnect the power supply before leaving.
Attention
It is strictly prohibited to placing any unrelated all-reflective or diffusion reflective objects in
the machine to prevent laser reflecting to human body or flammable materials.
Attention
The environment for the machine should be dry, free of interference and influences from
pollution, vibration, high voltage and strong magnet. The operating ambient temperature
ranges 5-40℃, and the humidity ranges 5-95% (no dew);
The machine should be far from electric appliances sensitive to electromagnetic interference;
Operating voltage: AC220V, 50Hz. Power-on is strictly prohibited in case of unstable voltage
of the power grid or unspecified voltage.
Attention
Chapter two of this manual is for Safety Rules. Please refer to the chapter more details
concerning safe operation of the machine. Users are required to carefully read and abide by
all the requirements of safety.

Equipment OverviewChapter 1
MF20 is a new generation fiber laser marking machine, which adopts modular design. The
optical bench, working platform and elevating working platform are separated and also can be
freely combined, which greatly improve the product's adaptability and flexibility. It is configured
with the new digital marking control system and powerful upper machine software, which can
meet the marking applications of different industries. It applies to stationary work surface
marking, rotary marking, mobile stitching marking, as well as assembly line marking on the fly.
The optical bench features multiple DOF adjustment functions (6 DOF), allows multi-directional
multi-angle rotation, and applies to the marking on different work surfaces. The core laser and
optical system are imported high-performance foreign products, which ensure that the machine
features better marking performance, higher accuracy, faster and more stable.
