Discription of Professional Kit Machine for Tattoo
Set the coil tattoo machine
Step #1: Find the gap between the front spring and contact screw's tip. If it is more than the thickness of 2 nickels, one over the other, the machine may not function properly. The recommended gap between the front spring and contact screw's tip is the thickness of a dime for lining and the thickness of a nickel for shading.
Step #2: Loosen the thumbscrew in order to release the contact screw.
Step #3: Adjust the contact screw until you get the recommended gap for lining or shading. After adjusting the gap, tighten the thumbscrew to lock the contact screw. Now, release the armature bar.
Step #4: Operate the tattoo machine at 10 Volts. This may be a little high for a specific use, but it is helpful for troubleshooting.
