Features: *Works great on metals, china, glass, plastic and other hard material. *Using the typical alternating current of frequency cycle, the equipment generates high-speed vibration to drive the high-hardness metal bit to engrave. *The speed can be adjusted to meet the requirements of different materials. *Pen design, hold and engrave just like writing, easy to operation. *Mechanical principle: The forced vibration (up and down vibration) is generated by the periodic characteristics of AC frequency to drive the pen tip to work, so there will be certain tolerable noise during the work. *It can engrave any permanent patterns and characters, with a large concave depth, which can reach up to 1mm according to the material hardness. *It is widely used for carving on the surface of almost all materials such as metal, jade, glass, plastic, marble, wooden, etc. Specifications: Product name: Electric Engraver Material: Metal + Rubber Color: Black + Blue Plug: European standard Volt/Power: 220V 25W Supply Voltage: 220V Max. Power: 25W Output Current: 0.1A Pen Bit: 3mm Engraving Depth: 01.1-0.5mm Repeat Engraving Depth: 0.3-0.8mm Suitable for: Chiseling Tips on Metal Wooden Glass Plastic Ceramics Stone Quantity: 1 Pc Instructions: 1. When in use, hold the body with your hand, tilt it at an angle (about 45 degrees) like writing with a pen, and place your hand on the table, do not press down hard when writing, the writing speed is slightly slower than usual. Move the carving on the real object. 2. Leave a trace where it crosses. 3. According to different materials, adjust the gears reasonably. 4. Master its performance through repeated engraving to meet the font size and depth requirements of different materials. Caution: 1. Continuous work should not exceed 20 minutes to avoid damage to the coil. Intermittent use can ensure the life of the body. 2. When the housing is heated, it should be used after cooling. 3. Turn off the power supply when not in use! Package Included: 1 Electric Engraver Note: 1.Transition: 1cm=10mm=0.39inch. 2. The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 3.
