2 Introduction
2.1 General Information
This manual is the designated user guide for the installation, setup, safe operation, and maintenance
of your fiber laser marking machine. It is divided into several chapters covering general information,
safety instructions, installation steps, operation instructions, maintenance instructions, and contact
information.
ALL personnel involved in the installation, setup, operation, maintenance, and repair of this
machine SHOULD read and understand this manual, particularly its safety instructions. Substandard
performance and longevity, property damage, and personal injury may result from not knowing and
following these instructions.
Your fiber laser marker works by emitting a powerful laser beam from its fiber laser source, sending
that beam through a fiber optic cable, focusing its power through the galvanometer lens, and using
this focused light to etch designs into certain substrates.
This fiber laser marking machine uses a nanoscale fiber laser source. Its single-mode output,
good heat dissipation, high efficiency, and compact structure make it ideal for high-precision laser
marking. With typical use, this device has an average lifespan of around 100,000 working hours.
However, constantly running your laser above 80% of its maximum rated power can significantly
shorten its service life. It is recommended to use settings from 10% to 75% of the maximum rated
power to enjoy optimal performance and longevity.
Note that this is a high-voltage device and, as a safety precaution, it is recommended to only touch
its components with one hand at a time during use.
Note also that this device has a protective housing, but without it the active laser is invisible to the
human eye and anyone in or near the working area MUST use special protective eyewear when
the laser is in use to avoid potentially permanent injury. Never operate this device if the casing's
exhaust system is not operating properly. The exhaust system must also fully comply with all
applicable laws and regulations for workplace and environmental air quality.
2.2 Designated Use
This machine is intended for engraving signs and logos on consumer products or applicable
substrates. This laser can process a wide variety of metals including steel, aluminum, titanium, brass,
copper, tungsten, carbide, and chrome. It can also be used with stone and some hard plastics such
as acrylic (See §1.6 Material Safety Instructions on Page 6 and §5.4 Instructions for Specific
Materials on Page 46 for further details.). The use of this system for non-designated purposes or
materials is not permitted.
