Chapter 4 Installation and Connection of Laser Cutting Machine
Installation steps summarize
Connect the electric line→ connect the water cooling machine with the main
machine body →connect the laser source with the machine body →connect the laser
head with the machine body →Inset the laser cable into the laser head and lock the
connection port →connect the laser source with the laser machine body →connect
the gas line, water line with the laser head →connect the air filter with the machine
body.
4.1 Electrical gas connections
a) Power requirements: 380V, 50HZ, laser electrical connections can be found in
the laser specification.
b) Carefully reading the attached machine tool electrical schematic diagram;
According to the laser cutting machine power wiring diagram wiring.
c) Check the total power and various power open action is sensitive.
d) Check the equipment power wiring is correct or not, as shown in the electrical
wiring diagram.
e) Check the total power open or not and other power open or not (e.g., host, laser
machine) must meet the capacity of drawing marked.
f) The wire diameter of power cord, ground wire and the zero line shall not be less
than the power wire diameter on the wiring diagram.
g) Check ground wire of power cord is connected or not.
h) Check the entire high voltage wire terminal (especially the input and output point
of power transformer) are reliable, strong, all of the plug and whether the board
connection is reliable.
Caution: T he power cord’s ground wire mu st be reliable
grounding . Ot herwise machine t ool ele ct rical signals wi t hin
t he t ank will be di st urbed and will be dangerous i f leakage
