Power Supply Memory Feature

Another great feature that is becoming more and more prevalent
in the tattoo industry is the memory feature. This will essentially
allow the artist to store a memory setting of voltage for each
machine so that the artist does not have to play with the voltage
knob to get it back to where it was while the artist was using
their liner machine setup ten minutes prior. This can be a handy
feature if the artist is using only 2 tattoo machines and alternating
back and forth between them.
