Sure, here is the translation for the instructions on purchasing and using laser tubes:

1. Laser tubes must be used in conjunction with a driver circuit board; direct application of voltage or current is not allowed.

2. For long-term operation, all laser tubes must have cooling systems in place.

3. To prevent electrostatic damage to the product, please wear anti-static gloves during assembly.

4. When soldering, the iron temperature should not exceed 300 degrees Celsius, and each solder joint should not take more than five seconds.

5. Due to the special nature of laser tubes, they cannot be returned or exchanged once used.

Please ensure that you follow these guidelines carefully to avoid any potential damage to the laser tubes and to maintain safety.
