The ignition switch position has been moved up, making thumb operation more convenient;
2. Temperature control system, the fan stops when turned on, and automatically starts when the temperature reaches 35 degrees, directly avoiding startup noise;
3. The light attenuation protection system stops working when the temperature exceeds 58 degrees, greatly extending the service life of the laser. (Light decay: Energy will weaken when the temperature exceeds 60 degrees, and light decay is irreversible);
4. Low battery warning, ignition warning, flashing light when low battery, flashing light when ignition to remind.
5. Redesign the air duct to increase the air output and significantly improve the heat dissipation effect;
6. Adding copper blocks has better heat dissipation effect, and with the assistance of the temperature control system, the single ignition time can be longer.
usage method:
1. Please keep the light outlet lens clean before use. The shortest usage distance is greater than 10 centimeters. When ignited, high temperature and reflection can burn out the lens and shell
2. Within an effective distance of 1-2 meters, new batteries are shipped with a default charge of around 50%. Please charge them promptly upon receipt
3. It is recommended that the single use time should not exceed five seconds. This laser is invisible light, and it is recommended to wear 974 wavelength laser goggles for use
4. It is recommended not to shine on reflective objects, such as mirrors. The first type of metal is metal, such as copper, silver, gold, etc; The second type is non-metallic, such as magnesium, silicon, silicon carbide, etc.
