Maintaining a
Proper Contact Point
By David H.
Your tattoo machine requires the
maintenance of a proper contact point to allow the optimal flow of
electricity. Therefore it is necessary to keep contact points in
good condition. Over time contact points may dull, become pitted
and appear slightly "burned". If this is affecting the performance
of your tattoo machine, it may be necessary to renew the point by filing
it smooth.
To perform
contact point maintenance you must remove the front spring/armature
bar/back spring portion. Loosen the back spring mounting screw.
Hold onto the end of the armature bar and slide the entire portion out.
Using a light file or emery cloth, gently sand from the base of the
front spring outwards. Maintain a steady and even motion as you do
not want the front spring to become uneven. When sanding is
completed, eyeball the front spring/armature bar/back spring portion and
adjust accordingly to make sure the tip of the armature bar and the tip
of the front spring aligns straight with the back spring.
With the
contact spring/armature bar/ back spring portion removed, you can also
sand the tip of the contact screw if it is in bad condition.
Again, sand lightly and evenly.
Re-attach
the front spring armature bar/back spring portion and be sure that it is
secured properly. Ensure that the tip of the aligned armature bar
and the hole of the tube vise is in alignment. The tip of the
contact screw and the front spring should also be aligned and centered.
This
procedure should only be done at most a few times. The front
spring should not be sanded down too much as this will also affect its
performance. It may be better to just replace the front spring
instead of sanding it. The contact screw is fine to sand down as
long as it has sufficient length to it. |
