This specific type of tattoo machine utilizes electromagnetic coils to drive a needle bar, creating the precise, rapid punctures necessary for outlining. It functions by passing an electric current through the coils, generating a magnetic field that pulls a spring-loaded armature bar down, which in turn pushes the attached needles into the skin. This up-and-down motion is repeated rapidly, depositing ink into the dermis.
Favored for its consistent power and ability to create crisp, clean lines, this device remains a popular choice among many tattoo artists. Its long history in the industry has led to numerous refinements and a deep understanding of its mechanics, making it a reliable and versatile tool. This robust construction contributes to its longevity and makes it suitable for demanding line work.
