Reading Time: 6 Minutes

"What voltage should I use?" is perhaps the most common question in every tattoo apprenticeship.

Set it too high, and you risk "chewing up" the skin and causing scarring; set it too low, and your lines will be shaky or the color won't stay. Finding the "Sweet Spot" for your tattoo machine voltage is an art form in itself, balancing hand speed, needle depth, and machine type.

In this guide, we’ll break down the secret science of voltage for lining, shading, and color packing to help you achieve professional results every time.

1. The Core Principle: Speed vs. Impact

Voltage essentially controls the speed (frequency) at which the needle moves up and down.

• Higher Voltage: The needle moves faster. This is generally for fast hand movements (Lining).

• Lower Voltage: The needle moves slower. This allows for softer transitions and less skin trauma (Shading).

Pro Tip: Your Hand Speed must match your voltage. If you move your hand fast but use low voltage, your lines will look like a series of dots. If you move slow with high voltage, you will damage the skin.

2. Setting Your Voltage for Success

While every machine is different (especially between Coil vs. Rotary), here are the industry-standard ranges for modern rotary machines like the Hawink Wireless Pen.

A. Lining: Bold and Precise (7.5V - 9.5V)

Lining requires a "clean" entry and exit. Because your hand usually moves faster when pulling a line, you need the needle to cycle quickly to create a solid, continuous mark.

• Small Liners (3RL-5RL): Stay on the lower end (7.5V - 8V).

• Bold Liners (9RL+): Increase the power (8.5V - 9.5V) to push that larger grouping into the skin.

B. Solid Color Packing: Saturated and Rich (6.5V - 8V)

Packing color requires the needle to stay in the skin just long enough to deposit the pigment without "chopping" the tissue.

• Moderate speed allows for circular motions that fill the area evenly.

C. Soft Shading & Realism: The Smooth Gradient (5V - 7V)

For black and grey realism or soft gradients, you want a "softer" hit.

• Lowering the voltage allows you to layer the ink slowly, building up depth without creating harsh edges.

3. Factors That Influence Your Voltage Settings

1. Machine Type: Rotary machines (like the Hawink CNC series) usually run at lower voltages compared to traditional Coil machines. Always check your manufacturer’s recommended range.

2. Skin Type: Tougher skin (like on the back or calf) may require a slightly higher voltage (+0.5V), while delicate skin (inner arm or ribs) requires a gentler touch.

3. Needle Resistance: Pushing a massive 25-Magnum requires more torque and voltage than a delicate 3RL.

4. Power Supply Quality: A cheap power supply may have "voltage sag." Investing in a high-quality, stable Tattoo Power Supply ensures your machine runs consistently without fluctuating mid-line.

Upgrade Your Power, Improve Your Art

Precision starts with your equipment. If your current power supply is inconsistent or your machine feels "bogged down," it's time for an upgrade. A stable current is the difference between a tattoo that heals perfectly and one that fades or scars.
