The term tattoo gun is a familiar one, often used by the general public to describe the handheld device that artists use to create permanent body art. While professional tattoo artists typically refer to it as a “tattoo machine,” the popular name “tattoo gun” speaks to its function of “shooting” ink into the skin. This powerful tool is the heart of the tattooing process, a marvel of engineering that has evolved dramatically over the centuries.
A Brief History: From Edison’s Pen to Modern Machines
The journey of the modern tattoo machine began not in a tattoo parlor, but in the laboratory of a famous inventor. In 1876, Thomas Edison patented the “Autographic Printing Pen,” an electric pen designed for creating stencils for copying documents. Its reciprocating needle, powered by an electric motor, would perforate paper, creating a pattern that could then be used for duplication.
It was New York tattoo artist Samuel O’Reilly who, in 1891, saw the potential of Edison’s invention for tattooing. O’Reilly modified the electric pen by adding an ink reservoir and a system for delivering the ink through the needle.
This groundbreaking invention, which he patented as the “Electric Tattooing Machine,” marked a turning point in the industry. It allowed artists to create tattoos with unprecedented speed and consistency, a stark contrast to the hand-poking methods that had dominated for millennia.
Just 20 days later, another significant development occurred. English tattoo artist Thomas Riley patented a single-coil tattoo machine, which laid the foundation for the coil machines we see today.
His design was based on the principles of an electric doorbell, using an electromagnet to create the buzzing motion. Later, in 1904, American tattoo artist Charlie Wagner further refined the coil machine, creating a design where the coils were aligned with the machine’s frame, a design that is still recognizable today.
The Two Main Types of Tattoo Machines: Coil vs. Rotary
Today, the world of tattoo machines is primarily dominated by two distinct technologies: coil machines and rotary machines. While they both serve the same fundamental purpose, their internal mechanisms, feel, and performance are vastly different.
The Coil Tattoo Machine
The coil machine is the classic, buzzing workhorse of the tattoo world. It is easily identifiable by its two electromagnetic coils and the distinctive, powerful hum it produces.
How It Works
The mechanics of a coil machine are based on a simple electromagnetic circuit. Here’s a step-by-step breakdown:
Power On: When the artist presses the foot pedal, an electrical current flows into the machine.
Electromagnetic Field: The current charges the coils, turning them into electromagnets.
Armature Bar Action: The energized coils attract a metal armature bar that sits above them. This pulls the armature bar down, causing the attached needle grouping to move into the skin.
Circuit Break: As the armature bar moves down, a contact screw that was completing the circuit is momentarily separated from a spring. This breaks the electrical circuit.
Spring Return: With the circuit broken, the coils lose their magnetic field, and a return spring pulls the armature bar and needle back up.
Cycle Repeats: The contact screw re-establishes the circuit, and the entire process repeats itself at a rapid, high-frequency pace, creating the signature buzzing sound.
Pros and Cons of Coil Machines
Pros:
Powerful: Coil machines are known for their powerful, hard-hitting action, which is often preferred for packing solid color and creating bold lines.
Customizable: Artists can easily tune coil machines by adjusting the springs, contact screw, and coils to achieve specific results, such as a faster, softer hit for shading or a harder, slower hit for lining.
Variety: They are available in various configurations (e.g., liner, shader, color packer), each optimized for a specific tattooing task.
Cons:
Loud: The constant buzzing can be a major drawback for both the artist and the client.
Heavy: They are generally heavier than rotary machines, which can lead to hand fatigue during long sessions.
Vibration: The significant vibration can be uncomfortable and affect an artist’s precision over time.
Complex to Maintain: They require more frequent maintenance and tuning to perform optimally.
The Rotary Tattoo Machine
The rotary machine represents a major leap in tattoo technology, offering a smoother, quieter, and more versatile experience. Unlike the electromagnetic coils of its predecessor, the rotary machine uses a small, powerful electric motor to drive the needle.
How It Works
The mechanism is much simpler and more direct:
Power On: An electric motor is activated, which spins a small, circular cam.
Rotational Motion: This spinning cam, located at the top of the machine, is attached to the needle bar.
Up and Down: As the cam rotates, its off-center position forces the needle bar to move up and down in a smooth, continuous motion. This drives the needle into and out of the skin.
Pros and Cons of Rotary Machines
Pros:
Quiet and Smooth: They operate with minimal noise and vibration, creating a more comfortable environment for both the artist and the client.
Lightweight: The absence of heavy coils makes them much lighter and more ergonomic, reducing hand strain.
Versatile: Many modern rotary machines are highly versatile and can be used for lining, shading, and color packing simply by adjusting the voltage or needle grouping.
Low Maintenance: With fewer moving parts, they are easier to clean and require less tuning than coil machines.
Cons:
Less “Punch”: Some traditional artists feel they lack the powerful, hard hit of a coil machine, which can be a matter of preference for certain styles.
Less Customization: While versatile, they offer less fine-tuning capability compared to the extensive adjustments possible with coil machines.
A Third, Modern Contender: The Tattoo Pen
A specialized type of rotary machine, the tattoo pen has become a dominant force in the industry, especially since the mid-2010s. Its design mimics a pen or marker, offering a natural and comfortable grip. Tattoo pens are lightweight, highly ergonomic, and almost exclusively use cartridge needles, which are sterile, single-use, and incredibly easy to change.
A Step-by-Step Guide: How to Use a Tattoo Machine Safely
Using a tattoo machine is a skilled art that requires extensive training and a deep understanding of safety protocols. This guide is for informational purposes and is not a substitute for professional apprenticeship.
Safety First: Before a single line is drawn, an artist must ensure a sterile and safe environment.
Sanitize Your Station: All surfaces must be disinfected with a hospital-grade solution.
Prepare Your Equipment: The tattoo machine, power supply, clip cord, and foot pedal must all be wrapped in single-use plastic barriers to prevent cross-contamination.
Sterile Supplies: Use brand-new, sterile needles and disposable tubes for every client. All ink must be poured into single-use ink caps.
Personal Protective Equipment (PPE): The artist must wear a fresh pair of nitrile gloves and, in many cases, a mask and apron.
The Tattooing Process:
Setting Up: The artist connects the tattoo machine to a power supply using a clip cord or RCA cord, and the power supply is connected to a foot pedal.
Needle and Grip: A new, sterile needle grouping is attached to the machine. A grip is placed over the machine body for a comfortable hold.
Power and Voltage: The artist adjusts the power supply to the appropriate voltage. Lower voltage creates a softer, slower hit, ideal for shading, while higher voltage creates a faster, harder hit for bold lines.
Inking the Needle: The artist dips the needle grouping into a new ink cap. The capillary action of the needle and tip draws the ink up, ready for application.
Application: The artist holds the machine at a specific angle and depth, gently pulling or pushing the needle across the skin to create the desired design.
Wiping and Re-inking: The artist periodically wipes away excess ink and blood from the client’s skin with a sterile paper towel and a soothing solution. They then re-dip the needle as needed.
Essential Maintenance and Sterilization
Proper cleaning and sterilization are paramount to preventing infections and maintaining equipment longevity.
After Each Tattoo:
Disassemble: The machine must be disassembled, and all single-use components (needles, tubes, ink caps) are disposed of in a proper biohazard sharps container.
Initial Cleaning: The reusable parts of the machine, like the frame and grip, are wiped down with a disinfectant wipe to remove any visible ink or blood.
Ultrasonic Cleaning: For coil machines, the metal components are placed in an ultrasonic cleaner with a special solution to agitate and remove microscopic debris.
Autoclave Sterilization: The gold standard for sterilization is the autoclave. This machine uses steam and high pressure to kill all microorganisms, including bacteria, viruses, and spores. Reusable parts are placed in sterilization pouches before being autoclaved.
For Rotary/Pen Machines: Since most modern rotary machines are designed to use disposable grips and cartridge needles, the cleaning process is simplified. The machine’s body and power supply are simply wiped down with a disinfectant, and the disposable parts are discarded.

The terms are often used interchangeably by the public, but professional tattoo artists generally prefer “tattoo machine.” The term “gun” can be seen as amateurish or misleading, as the device doesn’t “shoot” anything. It’s a precise instrument that delivers ink into the skin using a reciprocating or rotary motion.
How much does a professional tattoo machine cost?
The price can vary dramatically depending on the brand, technology, and features. Beginner kits can range from a few hundred dollars, while high-end, professional-grade machines from leading brands like FK Irons or Cheyenne can cost upwards of $600 to over $1,000 for a complete setup with a power supply and battery packs.
Are wireless tattoo machines better than wired ones?
“Better” is subjective and depends on the artist’s preference. Wireless machines offer unparalleled freedom of movement, a cleaner workspace, and are often more ergonomic. However, wired machines provide a constant, uninterrupted power source, eliminating the need to worry about battery life. Many professionals use a combination of both.
How deep does a tattoo needle go into the skin?
A tattoo needle is designed to penetrate the epidermis and deposit ink into the dermis, the layer of skin just below. The depth is very shallow, typically around 1-2 millimeters, or about the thickness of a few sheets of paper. This precise depth is crucial for a tattoo to remain permanent and to minimize skin damage.
What is the lifespan of a tattoo machine?
With proper care and maintenance, a high-quality tattoo machine can last for many years, often 5-10 years or even longer. The motor of a rotary machine may eventually need to be replaced, while coil machines might require new springs or tuning over time. Regular cleaning, lubrication, and responsible handling are key to extending the life of your equipment.
