The speed (Hz) and voltage you choose to run your machines at is down to personal preferance and your tattooing style.  There is a synchronicity that needs to be present between the tattooist and the machine he/she is using. A fast hand movement with a slow machine = chewed up skin. A slow hand with a fast machine will produce the same result. Therefore try to gauge wether your hand speed is slow or fast and adjust your machine accordingly. Try to tune your machine according to your pigment consistency too. A thick ink won't be injected into the skin sufficiently with a fast machine, again adjust your machine accordingly i.e. slow it down by backing off on the contact screw or using softer springs. Obviously you will need to increase the hit of your machine the bigger needle configuration you are using, do this by simply turning your ower supply up. The bigger the surface area of the needle the bigger resistance they will encounter from the skin thus needing more power to puncture the skin sufficiently enough to successfully deposit your pigments.

Be sure to maintain your machines by cleaning them regulary. Clean off any carbon deposits that may collect on the front of the coils by a little gentle filing.
