Understanding the use of a power supply is essential to the process of modern tattooing. The power supply
determines the speed of the needle moving through the gun and allows the tattoo artist to control the pace of
inking. Learning how to connect the various parts to the supply will assist you with beginning the process. Once
the parts are connected, you can experiment with speed settings and find a pace at which you are comfortable
performing. This will provide you background knowledge and experience for working as an apprentice with a
professional artist; do not attempt tattooing without professional training.
