Difference Between Coil Machines & Rotary Machines

1. Difference Between Coil Machines & Rotary Machines

2. Coil Machines The magnetic coil machine is a classic machine which uses an alternating electromagnetic current to pass through coils and turn magnets on and off in rapid succession. This pulls a spring loaded armature bar and creates an up and down motion, which results in the armature bar tapping the needles into the skin.

3. Coil Machines: The Pros & Cons Price : A good coil machine typically costs about $500. However, most artists need at least three machines. Depending on your setup, you may need over ten machines, which adds up quickly. Appearance : The appearance of a coil machine is more iconic and traditional. You also typically have more choices and customizations and can build your own coil machines.

4. Sound : The sound is a double-edged sword. Some artists love the buzz from a traditional machine, while others prefer the lack of sound from a pen or rotary. Vibration : Many artists find the vibration causes pain in their fingers, hands, and wrists during long sessions. Others complain that it can cause them to lose feeling in their hands after sessions. Weight : The weight is another double-edged sword. Some artists prefer the weight of the machine, while many others find it causes pain in their fingers, hands, and wrists when doing longer tattoos. Ease of Use : These machines are easy to regulate speed and power, but a tattooer needs to be familiar with the machine and how a machine works to effectively and correctly tune and operate it.

5. Replacement Parts/Customization : Parts are inexpensive, and machines are easy to customize and change Speed : Some artists find they can complete tattoos faster using coils. Cleaning : This is one of the biggest issues that comes with an EM machine, since the only way to autoclave the machine is to completely disassemble it and then autoclave the frame. Autoclaving these machines isn’t a logical choice. Tattooers also can’t spray the entire machine with a high-level disinfectant, because the disinfectants will erode the coils and damage the machine parts. This leaves the option to cover the machine in plastic and spray disinfectant onto a single use towel to wipe the machine (high-level disinfectants are recommended to be sprayed directly onto the surface and left on for 30 seconds).

6. Rotary Machines Rotary machines are powered by a motor that spins in a vertical circle. The needle bar is attached to the motor to move the needle up and down. Rotary machines are less customizable and require substantially less knowledge and finesse to be used effectively. Rotaries are sometimes autoclavable, but are more often bagged and then wiped down with a high-level surface disinfectant.

7. Rotary Machine : The Pros & Cons Price : Since rotary machines accept tubes that use a cartridge system, you don’t necessarily need more than one machine. However, the cost of one machine is typically higher than that of a coil (usually around $800). If you are not using the cartridge system, you run into the same issue as coils where you need multiple machines. Appearance : Rotary machines are less recognizable as a style of tattoo machine and typically have far less options and customizations.

8. Sound : Rotary machines make almost no sound, which is often viewed as a positive feature; the buzzing that is associated with a coil machine is loud and bothersome to many artists and clients. However, some artists love the distinct sound that comes from an EM machine. Vibration : Rotary machines don’t move the same way a coil does using springs, so they are much smoother to hold and don’t cause vibration, affecting the hand or skin. Weight : Most artists prefer the lightweight feel of a rotary over a heavy coil machine. Others find the weight of a coil helps to control the machine for more precise work. Ease of Use : While rotary machines require much less knowledge to operate, their settings aren’t as easy to control or configure. This is because they are made to be consistent across all the machines.

9. Replacement Parts/Customization : Due to the way rotary machines are made and designed, if something breaks or isn’t working the way the artist wants, the artist must either send the machine back for a servicing/repair or purchase another one. Speed : Some artists find they are much faster with a rotary machine. Cleaning : Most rotaries are either completely wipeable or autoclavable, which makes them a much safer machine to use to prevent cross contamination. Good tattooers will still wrap their machines in a barrier before tattooing.
