① The speed of the hand is faster than the speed of the motor (the hand has moved the machine before the needle has returned to the skin)
② Not adapted to the characteristics of the machine
Solution:
① Reduce hand speed operation
② Increase the voltage to increase the machine speed
③ If the integrated needle is operated, the rebound device is too soft and it will cause skin hanging. Replace it with a harder point to solve it.
Points to note when wiring is not practical:
① Is the amount of ink in the needle mouth sufficient?
② Is the depth of the lower needle sufficient?
③ Whether the skin is stretched or tight
④ Is the tattoo needle too loose?
