Electrical Safety Precautions-
electrical cabinet door, etc. Read the machine manual and electrical schematic carefully and
thoroughly to familiarize yourself with the functions and corresponding key operation methods. It
is forbidden to change the set machine parameters privately. If changes are required, they must
be trained by an equipment manufacturer and approved by an authorized professional, and the
values of the parameters before the change must be recorded so that the original state can be
restored if necessary.
Lasers for processing, generally with a supply voltage of several thousand volts to tens of
thousands of volts, should protect against the danger of X-ray damage from the high-voltage and
high-voltage electrons of the laser. Do not touch live components in the electrical cabinet during
power-on, such as numerical control devices, servos, transformers, fans, etc.
Warming Machine!
After power off, you must wait for more than 5 minutes before touching the terminal. A high
voltage is left between the power line terminals for a period after the power is turned off. To
avoid electric shock, do not touch it immediately. Oxygen is often used in laser cutting, and sparks
are splashed during cutting. Oxygen is a danger of fire. Therefore, there should be no flammable
or explosive materials in the work area, and appropriate preventive facilities, such as fire
extinguishers.
