VA tattoo exam Questions with Correct
Answers
"the making of needles" Materials
- Flat Needle Bar
-round needle bar
- eye loop
-drill gauge: tightens needle
- souder
Making of needles process
-clean and sterilize after making needles
-Tin the soldering iron
-drop the needle into Jig, lightly tap to ensure all needles are even ( pointed side should be
down )
-drop a small amount of flux at the end of the needle groupings, tap with soldering iron.
Diameter of a needle
Affects ink flow and puncture of the skin
Tapers
- Long Taper : Good for Lining
- Short Taper : Good for color
Coil Machine how does it work
Uses magnets to power machine which moves the armature bar and needles towards the coil.
, This pulls the needle into the skin, breaking the circuit, causing the needle to go back into the
machine
Coil Machine : Electromagnet ON - coils are not charged, the armature bar is up,
pulling the needle up
Coil Machine : Electromagnet OFF- coils are charged, pulling the armature bar down, pulling
the needle down
Tuning - voltage
-4 volts for shading
-5.5 volts for lining
Rotary
7-8 for either beginner lining or shading, 9-10 for lining
Tuning- CPs/Hertz
- Cycle per second
- 130 for lining
-120 for shading
How to adjust CPs/Hertz
- Adjust by moving contact screw
- Increase : moving closer to the front spring, this also shortens the stroke.
- Decrease: moving further from the front spring, this lengthens the stroke
Tuning: Stroke
