ABOUT THIS PRODUCT
FK Irons One Adjust
The FK Irons One Adjust is a next-gen wireless tattoo machine engineered for artists who need true versatility without sacrificing consistency. Its patent-pending adjustable stroke lets you move from crisp lining to smooth shading and dense color packing in seconds, keeping your session flowing without tool changes. A clear onboard display shows either volts or hertz, so you can dial in the actual needle frequency per second for precise, repeatable results across styles.
Built for demanding, full-day work, the FK Irons One Adjust ships with two quick-swap rechargeable batteries and a dual-bay charger, enabling continuous operation with minimal downtime. The aerospace-grade 6061-T6 aluminum frame is manufactured in the USA for durability, while the ergonomic grip stabilizes the wrist and supports fine control during long sessions.
Dimensions come in at 152 mm by 38 mm, with a balanced feel that stays steady regardless of battery choice. Weight is approximately 244 g with the 18500A pack and 268 g with the 18650A pack, giving you a predictable hand feel that helps maintain line quality and even saturation. The optimized electronics and brushed motor deliver a responsive hit across a wide working voltage range.
A two-year manufacturer warranty underscores its pro-grade build. The machine is also compatible with FK’s ErgoShield grips, streamlining setup while supporting studio hygiene standards. From blackwork and realism to color traditional, its stroke and frequency controls help you match the hit to your technique.
In practical use, the FK Irons One Adjust focuses on speed, control, and stability. Stroke adjusts from 2.0 mm to 5.0 mm in 0.5 mm steps without powering down, the display lets you monitor hertz or volts at a glance, and the modular battery system keeps your handpiece running as long as you do.
