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.

The biggest advantage of the tattoo machine's working mode is that it can generate high speed and large torque without being driven by motor or motor, and the power consumption of motor or motor is not considered. When working, the tattoo needle punctures the epidermis at a high speed and evenly. The tattoo pigment is implanted into the basal layer of the epidermis, so that the pigment can be permanently fixed on the epidermis, forming beautiful patterns and characters of various pigment combinations, so as to achieve the effect of modifying the skin and covering the epidermal scars.
