Main Parts
A. Cover—The cover provides access to the main bay for placing and retrieving materials, as well as fixing the laser
path alignment and other maintenance. Power to the laser is automatically cut when the cover is opened.
B. Viewing Window—The sepia-tinted acrylic window is shielded to protect you and others from the laser and its
reflection, allowing monitoring of the engraving process. However, you should never stare continuously at the laser
during operation, even through the window.
C. Warnings—These notices supplement the Safety Information chapter of this manual. Read them carefully before
using the machine and contact our customer service or tech support teams if you have any questions or concerns.
D. Temperature Gauges—These monitor the temperature of your laser power source and the tube's cooling water in
degrees Celsius (±3°C). Do not allow your power supply to exceed 38°C or your water cooling system to exceed
24°C. If the temperatures approach these values, stop work and allow your device to cool before further use.
E. Emergency Stop—This button immediately cuts all power to the laser tube in the event of an emergency.
F. Control Panel—The control panel offers hands-on control of your laser's intensity and includes a manual trigger
for testing and troubleshooting.
G. Rear Access Door—This door opens to the laser bay, holding the laser tube and its connections.
H. Laser Tube—This CO₂-filled glass tube is mounted on brackets and immobile. Its connection to the laser power
supply is extremely high voltage and extremely dangerous.
I. Power Socket—This socket connects to your main power supply. Be sure that the supply is stable and matches the
voltage on the label above the socket.
J. Ground Connection—This socket must be connected to a safe electrical ground (see §3.6) if your location does
not have a well-grounded 3-prong outlet.
K. Connection Inputs—These ports connect to your control computer and its engraving software using any of its
USB ports.
L. Exhaust Fan—This fan pulls out gasses and airborne debris from the worktable, sending it through your vent to a
window or air purifier.
M. Water Ports—These ports connect to your water pump or chiller to keep your laser tube cool and stable.
