GENERAL
DUAL PRO 14W LASER HEAD OVERVIEW
The new Dual Pro 14W laser head is the optical combination of two 7W PRO laser
diodes. They are combined and then the beam is collimated and compressed into
a square, increasing the power density and making the beam equal in both axis.
The magnetic shroud allows for easy mounting of the laser head to multiple
platforms and also provides a safety viewing window for the laser processing.
The focus lens of the laser has a fixed focus at ¼” below the shroud. Lifetime
of the laser at the recommended 3amp setting is 5,000 to 10,000 hours
depending on the environmental conditions.

GETTING STARTED
UNPACKING
Inspect the shipping container for damage. Verify the contents of the package:
- Dual Pro 14W Laser Head
- Focus Tool
- OD4+ Safety Goggles with Case
OPERATION
LASER FOCUS
The laser is fixed focus to ¼” below the laser shroud. For engraving, you can
focus the laser to the top surface of the material using the focusing tool
provided. For cutting, we recommend putting the focus at the bottom of the
material. For example, if you are cutting 1/8″ material, then set the focus of
the laser at 1/8″. If you are cutting ¼” material or more, then put the laser
almost touching the material to allow for the focus to be at the bottom.
BEAM PROFILE
The 14W Dual Pro laser uses proprietary technology inside the laser diode
package to decrease the total beam size while increasing the total power. This
makes it the smallest spot size possible in a diode laser. The energy from the
sides of the rectangle are superimposed into the center, increasing the power
density, reducing the spot size, and making the beam uniform.
Spot size on wood typical
is about 0.006 or less. On Acrylic, it is 0.0045. On tile it is 0.0035.
OUTPUT CONDITIONS
The laser diode output will vary depending on the temperature. Warmer
temperature environments will reduce the power of the laser. Do not have the
laser in under 0 degrees C. The laser diode will also require more current to
maintain the same amount of output power as the diode degrades.
NORMAL OPERATING CONDITIONS:
The laser diode will operate at its optimal level for thermal performance
at 3 amps. Additional current above this level will lead to possible
degradation of the laser output and thermal damage if additional precautions
for thermal management are not taken. It is possible to reduce the current on
the diode to increase the lifetime of the laser. Running at higher current
levels reduce the lifetime of the laser.
STATIC PRECAUTIONS
Take precaution when handling laser diodes as they are a static sensitive
devices. Static electricity and electrical surges will degrade the performance
of the laser diode.
LASER SAFETY
Laser light can cause damage to
eyesight and skin if proper laser safety is not used. Always wear the
appropriate laser goggles to prevent any laser light, either directly or
indirectly to contact the eye. Never expose skin directly to laser radiation.
Focused light will increase the safety hazard.
CLEANING THE LENS:
Sometimes soot or smoke can get onto the lens surface when processing, causing
decreased levels in output power. This is especially needed for cutting
projects. If your lens is dirty, then it will significantly reduce the power
level.
To clean it, use a q tip and isopropyl alcohol. Dip the q tip in alcohol and
then put it up into the lens holder and give it a twist or two to remove any
debris. Take the q tip out and let it dry for 5 minutes before use.
LASER CONNECTION
If your laser was part of a driver kit, it will be cabled with a Molex mini
fit Jr connector which will connect directly to the laser driver board output.
- Connect the laser to the Molex Mini Fit Jr. Header “H3” for laser output on the Dual Pro Driver Board.
MOUNTING
The laser has several magnetic mounting kits available. Check the product
website under the magnetic mounting kit section to see one for your machine or
use the generic magnet mount.
The magnet mount makes it easy to remove the laser when using the router to
carve. Simply disconnect the wires from the gantry connections and remove the
laser from the mount. When you want to use the laser, then reconnect the wires
and place the laser on the mount.
DISCLAIMER
- All statements of safety are only applied when the laser is used in its intended purpose.
- You are legally responsible for any injury to anybody resulting from the use of or assembly of the laser or their finished products.
- This laser as a COMPONENT for integration in a machine and is not a full laser machine and will be legally responsible from any and all LIABILITIES.
