Super Power 450nm 10W/15W/20W Blue Light Laser Module PWM For CNC EngravingParametersSize: 40*40*90mmWavelength: 445nm - 450nmLaser power: 10W/15W adjustable power manuallyControl method: PWM, switching frequency <9 kHzWorking voltage: DC = 12vWorking current: 3-5AAdjustable focus best focal length range: 5-30cmInstructions for use:The best working distance of the focusing model is 5-30cm, and the focal length of the fixed focus is about 2cmAs for the cutting power, if cutting 0-3mm wood, please use full power and the speed is 100mm/min Precautions:Please wear goggles before use. If the laser heat is serious, stop using it immediately to avoid exposure to the glasses and skin of humans and animals. Common problem:1: No traces can be carved①The focus of the laser head is wrong.The laser shines on objects of different heights, and the size of the focus is different. To be able to engrave normally, the focus must be the smallest②The object to be engraved is not suitable for engravingDue to the low power of the laser head we use, many flame-resistant, transparent, and thermally conductive materials cannot be engraved.③ The laser head is burnt outThe laser is easy to be damaged in high temperature environment, and it cannot work continuously for too long. Different files and settings have different heating conditions. Some of them start to get hot after 5 minutes, and some start to get hot after 10 minutes. Generally, after working for 10 minutes, touch the warm one with your hand. Is the temperature is high, you should take a break. Laser heating is serious and it is easy to break if it continues to work Package:1pc 450nm Blue Engraving Laser Module Leia Mais »
