Operation of tattoo machine kits

Tattoo is an art. If  you are hobbyist of tattooing,you certainly want to know how to operate the tattoo machine.
How to tune a tattoo machine kits to work is pretty stupid.  This post is for the super noob, the ones that we and every other tattoo supply company gets a phone call from every day, several times a day. 
See the gap arrow 1 is pointing to?  That is a dime width, this tattoo machine kits is set to work as a liner.  The dime gap liner and nickel gap shader is an old school method of tuning. 
It is also one of the most basic.  As one progresses, he will undoubtedly find variations on how to fine tune their machine for lining, shading, color packing, etc..  These variations take into account the thickness of the springs you got on, what wrap the coils are, what uf the capacitor is, etc..  So this is by no means an exhaustive tutorial on tuning, but it does give you newbies a starting point.
So heres the scenario: You get your brand new tattoo machine kits in the mail, anxiously rip open the package, hook it up to your power supply, press the foot pedal and…. nothing, not even a whimper.  Must be the builders fault right?  Wrong.  That piece of equipment you are holding is like an electric guitar, tune it right and it’ll make music.  Tune it wrong and it will do nothing.  Take a look at the picture below.
The only difference with us is that we are one of the only supply companies in this part of the western hemisphere that will bother to explain to a rookie how to tune their tattoo machine kits to work.
In this case,you don’t go to try to operate the tattoo machine.
