I'm Joshua South and I'm here to talk with you about how a tattoo machine works. The way a tattoo machine works is basically pretty simple. Energy flows into two coils and they become magnetic. This magnetism attracts a piece of metal called an armature bar. Attached to the armature bar is a group of needles. The armature bar moves back and forth anywhere from one and a half millimeters to three and a half millimeters. The needle points are dipped into pigment and then injected into the skin at a rate of two thousand to three thousand times per minute. There are a few different types of tattoo machines. There is a rotary tattoo machine, an electromagnetic tattoo machine, and a pneumatic tattoo machine. An electromagnetic tattoo machine is driven by magnetism. A rotary tattoo machine is gear driven. And pneumatic machines are driven my air pressure. I personally use rotary tattoo machines for coloring and electromagnetic tattoo machines for lining and shading.
