In the early days, tattoo machines were rough, mostly made by hand, with high manual manufacturing cost and single pattern. At that time, the electric tattoo machine beat 1000 times per minute, only stabbed the skin, and the depth was only 0.8-1 mm.

The tattoo machine converts the external 220V AC into the DC with a voltage value between 3-20V through the intermediate voltage regulator and transformer. Under the DC voltage of 3-20V, the two main coils and the electronic injection point produce instantaneous suction and spraying effects. With the reciprocating movement of the tattoo machine spring, the tattoo needle is driven to produce high-speed up and down and reciprocating movements.
