Recently when tattooing I've noticed the voltage lowering as soon as I use my pedal,when I release the pedal the voltage starts to go back up on my power supply. As soon as I use my pedal again the same thing is happening,I'm really not sure what it is that is causing this,any suggestions!?
Just a suggestion, bypass the pedal i.e. get a jack plug and join the 2 wires together to identify if it is the pedal, what machine are you using? Also bad clip cords can cause problems as well as poorly set up coil machines or Chinese coils. Was it working ok before and just suddenly developed a fault with out you carrying out and mods etc.
