1. Mechanical principle:
The frequency cycle characteristics of alternating current are used to generate forced vibration (up and down vibration) to drive the pen tip to work. Therefore, a certain tolerable volume will be produced during the working process (engraving pens based on this principle have a certain volume)
2. How to use:
Slightly tilt it at an angle (about 45 degrees) like holding a pen to write, and place your hand on the table. Do not press down hard when writing. The writing speed will be slightly slower than usual. The writing stroke can be adjusted by adjusting the gear. Master its performance by repeatedly engraving to meet the font size and depth requirements for engraving different materials.
3. Suitable engraving materials: wood, metal, stone, jade, etc.
4. Notes:
Continuous operation should not exceed 30 minutes to avoid damaging the coil. Only intermittent use can ensure the life of the machine. When the casing is hot, it should be cooled before use. Please turn off the working power when not in use! ! !
