When the armature bar is flat on the front coil, what is the smallest gap above the
rear coil?
.010
What does a smaller gap above the rear coil cause?
More Power
What should armature bars be made of?
Plain Steel
How does a machine run if too much of the coil core is showing?
Hot
Where on the front spring should the contact screw be hitting?
Front or End of spring
What length of spring would run faster?
Short spring with a high angle
What type of metal should the contact screw be made of to have the highest
conductivity?
Brass
How does the armature bar hit the front coil core?
Flat, full contact

What do you want the frame on your tattoo machine to be?
Non-conductive
What happens when your machine is conductive or electrified?
The armature bar sticks to the coils causing the machine to stay in an "on" setting
What diameter should your binding post be?
5/16
What happens if you use a steel contact screw?
Can cause unwanted spark
When setting up your machine, why would you "snug" down the eye of the
needle bar?
This helps to prevent weak and jumpy lines
Why is a one-piece contact screw the best choice?
Screws with things added on top can add to the vibration
What are the two advantages to using a brass contact screw?
100% conductive and keeps its shape longer than other choices
How much of the contact screw needs to be touching the front spring?
A tiny contact area
Why should you use plain steel for a spring rather than a coated spring?
The coating wears away quickly, which causes a bad connection
What kind of reaction can you expect from a machine with a very low spring
angle?
Spongy and weak

Which type of machine benefits the best from a shorter spring?
A liner
Which spring is the most important for tuning the machine?
The rear spring
A machine that is very hard hitting and fast running moves the needle in and out
of the skins so fast that ____________________________________?
It doesn't leave enough pigment behind
What is the ideal width of the springs used on the machine?
The springs should be just as wide as the part that they are attached to
What types of screws should you use to hold the coils to the frame?
Always use a magnetic screw that sits flush to the frame
What is the function of the tube vise?
Firmly hold the tube in place and properly align the tube while the machine is in
use
How should a tube vise hold a tube in comparison to the machine?
Squarely front to back and side to side
What is the most important part of a tattoo machine?
Coils
What is the purpose of the coils of a tattoo machine?
To run consistently and not lose power
What is a possible reason for the machine to not work at all?
There is debris between the contact screw and the front spring
, 4|Page
What can cause the coils to be in a constant "on" position?
A coil wire, soldering lug, or any of the electrical circuit is touching the frame
What does your frame act as for the coil circuit?
The ground
What is not a purpose of the binding posts?
Electrical contact from the soldering lugs to the contact screw
What is a safety feature of the cartridge needles?
If the cartridge is not installed in the machine or tube, then the needles are not
exposed; this limits the possibility of a needlestick
What does EPA stand for?
Environmental Protection Agency
What does FDA stand for?
Food and Drug Administration
What does "high level disinfectant" mean?
A chemical agent, registered with the EPA, which has demonstrated
tuberculocidal activity
"Office" in the tattoo laws refers to what?
Health licensing Office
What attributes does a container have to have to be considered a "Sharps"
container?
Puncture-resistant, leak proof, labeled with a biohazard symbol
How many hours are part of the tattoo licensing program?
360 hours consisting of 210 theory hours and 150 practical hours
