PMU Equipment & Techniques 2

Question 1

What is the primary difference between a rotary PMU machine and a coil machine?

Accepted Answer

Rotary uses a motor-driven cam; coil uses electromagnetic coils

Answer

Rotary machines use a rotating motor/cam to drive the needle, while coil machines use electromagnetic coils to create the up-and-down motion.

Question 2

Which needle configuration is BEST suited for shading and powdering effects in PMU?

Accepted Answer

Curved magnum (curved mag)

Answer

Curved magnum needles distribute pigment over a wider area with softer edges, making them ideal for shading and powder brow effects.

Question 3

At what angle should a PMU artist typically hold the handpiece when performing a hair-stroke technique?

Accepted Answer

45 degrees

Answer

A 45-degree angle is the standard working angle for most PMU machines to achieve proper needle penetration depth and stroke control.

Question 4

What does 'machine speed' (measured in Hz or voltage) affect in PMU work?

Accepted Answer

The rate at which the needle penetrates and retracts per second

Answer

Machine speed (Hz/voltage) determines how many times per second the needle strikes the skin, affecting trauma level and pigment implantation.

Question 5

Which of the following best describes 'needle depth' in PMU?

Accepted Answer

How far the needle protrudes from the tip of the cartridge during operation

Answer

Needle depth refers to the amount the needle extends beyond the cartridge tip as it operates, determining how deep pigment is deposited in the skin.
