Power fault protection preventing the beam from activating after a power failure. LED indicators that indicate different states including armed and when the laser is active. Precision laser trimmed regulators provide constant current to the laser. High power 5A current source. Soft start for diode protection.True PWM control for smoother gray scale images. LED status lights for input laser enabled and laser on. Laser test functionality for easy and accurate laser positioning. 2-1/2 exhaust port for attaching a smoke removal device. When operating the CNC laser you should always wear the red protective glasses supplied with the unit. The laser should be operated with extreme caution and avoid eye or skin exposure to direct laser light. OTHER IMPORTANT INFORMATION TO KNOW.
All lasers will emit smoke as they burn into the material, while the amount of the 2-watt version is minimal, the 4 and 7-Watt can be considerable. Excessive smoke can shorten the life of the laser diode by clouding the lens causing it to reflect back into itself and prematurely burning it out. We highly recommend using some type of smoke removal system, such as a dust collector, shop vac with Hepa filter, or an exhaust system like NWA item #20138Laser. You should periodically lightly clean the laser lens with a cotton swab and hydrogen peroxide or a camera lens kit.
