LT-K20 (Optical Power 20W) Features:
LaserTree K20 is a true 19-21W output optical power laser engraving and cutting module. It uses beam compressed technology to combine 4pcs 5W laser diodes into a powerful laser beam with 20W laser power.
2. Powerful Cutting Ability
12mm basswood plywood: 100mm/min, one pass
15mm black acrylic: 15mm/min, one pass
15mm pine wood: 100mm/min, one pass
9mm MDF: 100mm/min, 2 passes
3. Built-in Air Assist Airway & Dual Fan Cooling Design
1>Built-in air assist airway to get clean-cut edges, improve cutting performance.
2>Excellent heat dissipation makes the laser module maintain a stable cutting ability and prolong service life.
4. Working Status Indicator
The electrical connection status can be easily checked by the "Power" and "Signal" LED indicator.
5. Temperature Display & Alarm Function
Excessive working temperatures can reduce the life time of the laser head at an accelerated rate.
LaserTree K20 create a solution with working temperature display,so that you can check the internal temperature of the module easily. When the working temperature of laser module over 55 ℃, it will sound an alarm through the buzzer.
6.Red Cross Line Locating
The working frame can be positioned by red crosshair, it is helpful for improving the convenience of the secondary cutting and engraving as well.
7. Copper Core Protection Lens.
Easy to clean and replace when the lens is contaminated or dusty.
8. Laser View Window
Anti-blue light view window with optical glass material, protective your eye from blue light, no fear of fiames.
For Cutting
Please make the focus locate lower than the cutting material surface.
For example, if you want to cut 10mm material, the focus should be 5mm lower than material surface, please adjust the fixed focus lever to 5mm.
LT-80W-AA-PRO (Optical Power 10W) Features:
1.LT-80W-AA-Pro
It has an upgraded nozzle compared to the previous LT-80W-AA. The difference of this nozzle is that it has an advanced hydrodynamic design that makes better use of air pressure. When using the same air compressor, the upgraded version has a faster jet airflow.
2.With the air asssit nozzle
The laser head comes with a specially designed air assist nozzle. When cutting with this laser head, the air assit system will blow air through the air nozzle. That will bring you excellent cutting experience and greatly reduce burned marks.
Air pump suggestion: Air pressure and capacity: ≥0.027kPa, 27L/min
3. Remarkable cutting ability
Cutting 8mm bass plywood ,120mm/min ,one pass.
Cutting 5mm bass plywood, 50mm/min, one pass.
Cutting 5mm MDF by 2 passes, 150mm/min , 2 passes.
4.With the laser protective cover
Comes with a removable protective cover. Whether engraving or cutting, use this shield to filter blue light and work without laser glasses, convenient and fast. It's also easy to remove if you don't need it.
5. Widely Compatible Design
LT-80W-AA-Pro laser module can be installed on Z*aitu,O*tur,Tw* Trees,S*ulpful9, Xtool, A*omstack and other models of DIY laser engraving machines.
(If you are not sure if it is compatible, please send us a picture of your machine’s contro board, we will provide you with a connection diagram.)
With Air Assist VS No Air Assist
Using air assist helps to cool the material and prevent heat damage, and also helps to remove any debris and fumes generated during the laser cutting process, resulting in a clean cut surface.
Interface diameter size
Air nozzle outer diameter: 6mm; inner diameter: 3.5mm
Air tube outer diameter: 8 mm;inner diameter: 6 mm
Air pump suggestion: Air pressure and capacity: ≥0.027kPa, 27L/min
Provide spare protection window piece
Debris and fumes from the laser cutting process are blown onto the lens, providing a spare lens for better cleaning and replacement.
For cutting work
The ideal position of the focal point is in the middle of the material, the cutting focal point of LT-80W-AA is 45mm, the length of the air nozzle is 39mm, so the focal point position is 6mm below the air nozzle. For example, if you want to cut 8mm plywood, the distance from the air nozzle to the surface of the material should be 6mm-8mm/2=2mm.
For engraving work
The focal point is at the surface of the material.
When the laser module is not used for a long time, please ensure that the lens is not polluted by dust.
When you replace the air nozzle, please ensure that your operation will not pollut the lens. Finger prints or dust on the lens will weaken the output power of the laser module, or even damage the lens.
When you find the cutting ability decreases, the lens might be not clean. Please use a clean alcohol swab to clean it according to the following figure.
