Use a machine with stable and soft strength (softer shrapnel). The stability of power depends on many aspects, including coil, frame, shrapnel, armature, magnet, capacitor, power supply.
2. Adjust the spacing (the distance between the armature and the coil) to a proper value (about 3 to 5 mm). The adjustment of this spacing is not by adjusting screws, but by adjusting the bending of the rear shrapnel. The adjustment screw only needs to lightly touch the top of the front shrapnel. Do not put too much pressure on the front shrapnel, so that the shrapnel cannot exert its maximum effect. The machine that just adjusted the shrapnel needs a period of operation to stabilize, because the steel has its own memory.
3. According to the number of needles, adjust the length of the needle output (the distance from the needle tip to the needle mouth when the machine is operating) (for example, the cutting needle is 3 mm and the needle is 1.5 mm, the cutting needle 9 is 3 mm, and the fork is 5 needles) When the needle is 2 mm, the 15-row fork needs 5 mm. Because the more needles, the larger the force area, the greater the resistance given to the needle by the skin, and the shallower the penetration, then the force needs to be increased. ).
4. The power supply of the machine needs to be stable in voltage, large in current intensity (more than 1.5 amps is required), and the adjustable range is large. In this way, different machines and different needles can be applied.
5. The adjustment of the power supply and the spacing of the shrapnel determine the power of the machine. Try to reduce the power of the machine as small as possible, as small as you think it is good enough for coloring. The basic concept is to first adjust the distance between the coil and the armature to the appropriate value, and then adjust the voltage knob of the power supply to the minimum first, and then slowly increase it until there is a little sound of the machine. A little bigger), this time should be almost the same (remember, the adjustment here refers to the last after the needle is installed). But it is not necessary, and needs to be adjusted according to your own methods and habits.
6. Clearly know what color and concentration of colorants penetrate the skin to the chroma that can be achieved after recovery, try to pierce the colorants in one step, and reduce waste needles. This requires a strong artistic foundation and long-term tattoo experience.
