4. Gently rub the mirror surface with a dry cotton swab in the same manner while the surface is still dry. 5. If necessary, repeat the process until satisfied, using new cotton swabs each time. 6. For stubborn water stains, use a mixture of absolute ethanol and absolute ether for final treatment. - Page 41 Unscrew out the sealing cap before adding water. 2. Filter Cleaning a. Regularly clean the dust filters located on the sides and front of the cabinet to ensure proper ventilation and heat dissipation. 3. Cleaning the welding nozzle a. Extended use of the tip of the nozzle can lead to the accumulation of slag, obstructing the flow of shielding gas and affecting the laser energy delivered to the material surface.
