Instructions for use

- Please connect pins to wires by solder instead of using socket when operation current is higher than 6A. - Soldering point should be close to the middle of the pins. Soldering temperature should be lower than 260℃ and time shorter than 10 second. - Make sure the fiber output end is properly cleaned before operation of laser. Follow safety protocols to avoid injury when handling and cutting the fiber. - Use constant current power supply to avoid surge current during operation. - Laser diode must be used according to the specifications.
