Frequently Asked Questions
  • A rotary machine uses a motor to drive the needle in a smooth, consistent circular motion. A coil machine uses electromagnetic coils to create a hammering motion. Rotary machines are quieter, lighter, and easier to maintain — which is why most professional artists in the US and Canada have moved to rotary for daily studio work.
  • Fine line and single-needle work performs best at 2.5–3.5mm stroke. Shorter stroke means less needle displacement per cycle, which gives you more control over placement and reduces the risk of blowout on delicate lines.
  • Voltage depends on your needle configuration, skin type, and technique. Most lining work runs between 6.0–8.0V. Shading and grey wash typically runs 5.0–7.0V. Fine line and single-needle work runs lower, around 4.5–6.5V. The full breakdown is in the voltage guide.
  • Torque is the rotational force the motor produces — measured in millinewton metres (mNm). Higher torque means the motor maintains consistent needle speed under resistance from skin. Low-torque motors slow down or bog when needle resistance increases, causing uneven ink deposit.
  • Wireless machines offer freedom of movement, cleaner station setup, and no cable management. Corded machines offer unlimited runtime and consistent power independent of battery charge. Most professional studio artists in the US now run wireless as their primary machine, with corded as a backup or specialist tool.
  • Wireless rotary machines require minimal maintenance compared to coil machines. Clean the grip and cartridge area after every session, check the battery contacts monthly, and inspect the motor connection every 3–6 months depending on session volume. Full guidance is in the maintenance guide.
