Types of Tattoo Guns

Types Of Tattoo Guns

Rotary Tattoo Machines

Rotary tattoo machines are powered by an electric motor which drives a needle up and down. They are the most commonly used type of tattoo machines and are preferred for their reliability and precision. Depending on the design, these machines can be used for lining, shading, and coloring. The needles used in rotary machines are usually soldered onto a circular bar which allows for a more precise and consistent line.

Coil Tattoo Machines

Coil tattoo machines are powered by an electromagnet and use electromagnetic coils to drive the needles up and down. They are often used for lining and shading as they have a higher frequency, allowing for more precise and consistent work. Coil machines are generally heavier than rotary machines and require more maintenance. The needles used in coil machines are usually soldered onto a metal bar.

No matter which type of machine is used, understanding how do tattoo machines work is the key to achieving successful tattoos. Both types of machines use needles to puncture the skin and inject ink, creating a permanent design. However, the difference lies in the way the needles are driven up and down. Although both machines are capable of creating beautiful tattoos, it’s important to understand the intricacies of how each machine works in order to get the best possible result.

The motor powers the tattoo gun and is the core component that allows the machine to work. The motor is usually an electromagnetic coil, which is able to generate a strong magnetic field when energized. This magnetic field is then used to move the needle arm up and down rapidly and repeatedly to create the desired tattoo design.


The needle is the part of the tattoo gun that actually pierces the skin and injects the ink. It is attached to the needle arm, which is in turn moved up and down by the motor. The needles come in various sizes and shapes, and the size and shape determine the type of tattoo that can be created.


The tube is the part of the tattoo gun that holds the ink. It is usually made of plastic or metal and is connected to the needle arm. The tube allows the ink to flow through the needle arm and into the skin.

Power Supply

The power supply of a tattoo gun is an essential piece of equipment. It is usually a battery or an electrical cord. The power supply provides the necessary power to the motor, allowing it to create the strong magnetic field needed to move the needle arm. Without a power supply, a tattoo gun would not be able to work.

A tattoo gun is a complex piece of machinery, and understanding how does a tattoo machine work is essential for anyone considering getting a tattoo. By understanding the components of a tattoo gun and how they work together, it is easier to choose the right equipment for the job.

Rotary Tattoo Machines

Rotary tattoo machines use a motor to power the needle. The motor is connected to the armature bar, which is responsible for moving the needle up and down. It is controlled by the artist’s hand and is used to create a consistent and precise line. The motor also powers a capacitor, which is a device that stores energy and allows the machine to maintain a consistent speed. This helps create a smooth and even tattoo.

Coil Tattoo Machines

Coil tattoo machines are powered by electromagnetic coils. These coils create a magnetic field that causes the armature bar to move up and down, pushing the needle into the skin. The coils also regulate the speed at which the needle moves, allowing the artist to create a precise and consistent line. The power of the machine is determined by the size of the coils and the amount of voltage they can produce. This allows the artist to control the depth and intensity of the tattoo.

Tattoo guns are an essential tool for any artist, allowing them to create beautiful, custom designs. By understanding how they work, artists can better control the depth and intensity of their work, ensuring the best results for their clients. Knowing how do tattoo guns work can help any artist create unique and stunning tattoos.
