VA TATTOOING PSI FINAL PAPER 2025/2026 QUESTIONS
WITH ANSWERS GRADED A+
✔✔Parts of coil Tattoo machine - ✔✔- 2 coils
-yoke
-frame
-tube
-tube clamp
-grip
-needle
-tip
-needle bar
-armature bar
-front spring
-contact screw
-o-ring
- rear spring
- rear spring mounting screw
✔✔Front Spring - ✔✔- fixed to the same point of the rear spring, not attached to the
frame
-not attached so the bar can move
- bend at an upward angle so it can reach the contact screw
- to adjust the angle of the front spring, rubber grommets or o-rings can be used
because of their different widths
✔✔Armature bar - ✔✔- made of magnetically responsive metal
- responsible for moving the needle
- fixed on the machine by a rear spring that allows the bar to move up and down
- at the front of the bar is the front spring
-the electromagnetic force of the coils pulls the armature bar down, opening the circuit
when contact is made
- the electromagnetic field then dissipates, causing the armature bar to leap upwards
causing the front spring to make contact with the contact screw.
✔✔Contact screw - ✔✔- binding posts act as electrical connections
- the front binding post is connected to the negative lead and also holds the contact
screw.
- the the armature bar is is released from the coils electromagnetic field, the front spring
leaps upward to touch the contact screw and complete the circuit.
- the length of the contact screw can be adjusted to control how far the armature bar
has to travel upwards
✔✔O-rings - ✔✔Gives tension on front and back springs
, ✔✔Rear Spring - ✔✔- rear spring is fastened to the machine frame by a secure
mounting screw and attached to the armature bar
-the rear spring controls the downward force of the machine
- thinner spring : machine moves with less force
-thicker spring : machine runs with a greater force
✔✔Coils - ✔✔Pieces of iron with copper wires wrapped around them.
Amount of wire affects the power, more wire = more electricity conducted from the
power source aka " hit harder", less wire, less power.
✔✔8-coil - ✔✔Fine Lines & smaller needle groupings
✔✔10-coil - ✔✔Thicker outlining & shading, use with 8-12 liners
✔✔12-coil - ✔✔Shading big areas, use w/ 11-17 mags
✔✔Grommets - ✔✔Small little rubber piece for a tight grip
✔✔Capacitor - ✔✔Small tube like component the connects to the positive and negative
coil leads. It acts as a regulator for the Amount of power circulating in the coils, which
moves the armature bar
✔✔the smaller the capacitor - ✔✔The less volume, so the chargers get exchanged
quicker, which allows the machine to run faster
Great for liners
✔✔The larger the capacitor - ✔✔More volume, allows the machine to run a bit slower
Great for shaders or color packing
✔✔Tools needed for coil machines - ✔✔-Allan keys
-screwdriver
✔✔Depth of which needle should go into skin - ✔✔1-2mm of needle tip extending out of
the machine
✔✔Rotary machine - ✔✔- uses a " direct drive" motor, driving the cam wheel, moving
the needle up and down as it rotates
✔✔Cam wheel is up - ✔✔When the grommet on the cam wheel is at it's highest point,
the needle is inside the tube
