I am reallyyyy new to tattoo art but I am responsible and patient with the process. I do have cheap scratcher equipment but would like to start practicing, only on practice skins. When I run my machine, it makes a clicking sound and I think the needle setup is trying to move but it won’t run. What am I doing wrong? I turn my power source up slowly and my contact post is touching the front spring. When it does work it seems kinda dodgy however. Thanks for the help.
