Electric engraving pen is a compact, lightweight, and portable tool designed for easy handling and operation. It is widely used in research, industrial production, commercial applications, and home projects for marking and labeling purposes. This engraving pen provides a fast and permanent marking solution on a wide range of materials, including metals, ceramics, plastics, and wood. Working Principle: The device operates using AC frequency to drive mechanical vibration for engraving. During operation, a low-level ble sound is produced — this is normal and common to all engraving pens based on this principle. Users sensitive to sound should take note. Usage Instructions: Hold the pen at approximately a 45-degree angle, similar to holding a regular pen. Rest your hand comfortably on the work surface. Apply light pressure while engraving; write at a slower pace than normal handwriting. Adjust engraving depth and font size by modifying the travel gear and practicing on different materials to achieve desired results.
