Hertz vs. Volts

The Display Dilemma

If you grew up using a standard rotary or a coil machine, you think in Volts. You know that 8.5V "feels" right for your liner. But then you see an artist using an ACUS M1 or a Cheyenne SOL Nova, and their screen says 110 Hz.

Are they tattooing at 110 Volts? (Definitely not). Are they using a secret language? (Sort of).

At DialedIn.ink, we believe that understanding the difference between electrical potential and physical frequency is the "Level Up" every apprentice needs.

Volts: The "Gas Pedal"

Voltage is electrical pressure. Think of it like the gas pedal in a car. When you push the pedal (increase Volts), you are telling the motor to spin faster. However, every car (machine) responds differently to that pedal.

• A lightweight Tier 2 rotary might hit 100 cycles per second at 8V.
• A heavy-duty Tier 1 machine might only hit 80 cycles per second at that same 8V.

Voltage is what you give the machine; it isn't necessarily what the needle does.

Hertz (Hz) & CPS: The Speedometer

Hertz is a measurement of frequency—how many times something happens per second. In tattooing, 1 Hz = 1 Cycle Per Second (CPS).

When a high-end German machine like the ACUS M1 shows "130 Hz," it is telling you exactly how many times the needle is reciprocating every second. This is far more precise than Volts because it describes the physical reality of the needle hitting the skin, regardless of the power supply brand.

Why the Sync Matters

If you are moving your hand at a "Fast-Moderate" pace but your machine is only running at 70 Hz (CPS), you will get "pixelated" lines because the needle isn't hitting often enough to fill the gap. To fix this, you don't just "turn up the heat"—you need to sync your Cycles Per Second to your Hand Velocity.

The DialedIn Translation

Most apprentices don't have a machine that displays Hertz. You have a standard power supply that shows Volts. This creates a "blind spot" in your technical setup.

The DialedIn Engine was built to solve this. When you select your machine style and hardware in our tool, we use known motor constants to translate that Voltage into a Derived CPS.

• We show you the Voltage (what to set on your box).
• We show you the CPS (what your needle is actually doing).

Master the Physics

Stop treating your machine like a black box. Whether you're using a budget-friendly Mast Archer or a pro-standard Cheyenne, the goal is the same: Total Control.
