1Voltage Range: The machine operates at a voltage range of approximately 5-10V under load, ensuring a smooth tattooing process while maintaining precision and stability. 2Lightweight Design: The machine features an aluminum alloy frame, making it lightweight and minimizing vibrations. This allows artists to operate with ease and reduces fatigue during the process. 3Efficient Creation: The machine operates at high speeds, allowing for the quick creation of precise lines and shading. High-quality needles cartridges offer superior penetration, resulting in vibrant and long-lasting colors. 4Stable Operation: The motor is wound with high-quality copper wire, providing high-frequency needle output speeds. This ensures better heat dissipation and lower noise levels for the machine.
