What Voltage Is A Rotary Tattoo Machine? – Fun Things To Know!

What voltage is a rotary tattoo machine? This question might seem like it’s impossible to answer, but the truth of the matter is that you can find out by doing some research.

We recommend searching for answers in this article about how different tools work in electrical current requirements to avoid getting stuck trying to figure everything else out at once!

What Rotary Tattoo Machine Basis Do You Need To Understand?

When looking for a rotary tattoo machine power supply, it is important that the one picked can handle what’s in store. As with any equipment or piece of tech, there will be different settings and preferences depending on personal preference.

The device converts 110V or 220V AC to 2 – 18 volts DC which will be suitable for operating any equipment you might use.

There are two kinds: rotary one, like on an electric motor with a rotor and stator, or coil one that uses coils wrapped around steel cores. Whichever kind you choose should work well in most cases since they both deliver high-quality results, but we will focus on rotary only in this article.

What Voltage Is A Rotary Tattoo Machine?

There are different setups for the voltage of a rotary tattoo machine, but the recommended one is 7.5 to 8.5 volts for coloring and 8 to 9 volts for the lining.

The power supply is an important part of the best rotary tattoo machine because it can either slow or speed up the motor, depending on what you choose. 

The higher the volts, the faster your work will be and vice versa; low volts make things move much more slowly in comparison. 

Some high-end supplies offer digital readouts so that users know exactly how fast their instruments run at any given moment without even looking. 

Maintaining the correct number on the motor and choosing the right ink brands are crucial to help you keep up with your customer’s expectations.

The Difference In Voltage Settings


A pre-set is found with a regulated one. The appliance’s power has no standard on choosing it because various brands have a different range to adjust. These regulated tools keep the same voltage throughout your tattooing process.

There’s no easy way to adjust the volts on your engine, so you’ll need some practice depending on what kind of artwork and hand speed is used that works best for you!


For unregulated, turn it up during outlining to reach a necessary speed. On the other hand, more detailed lines require a slower movement speed when shading, so it’s best to turn down for finer details.

Steps Of Setting Up A Rotary Tattoo Machine

Wash your hands clearly before setting up your device.

  1. Attach a rubber nipple to the needle bar pin.
  2. Adjust the retainer screw to create room for the bar and tube.
  3. Carefully insert the needles into and input the tube into its clamp.
  4. Fit the bar loop to the nipple tightly.
  5. Hold the needle bar pin and press it downwards.
  6. Adjust the needle bar to attach with the retainer rings.
  7. Tighten it to hold the needles in place
