FK Irons One Adjust wireless tattoo machine with adjustable stroke

The FK One Adjust is designed for artists who want one machine that can truly do it all. With an adjustable stroke ranging from 2.0 to 5.0 mm — in precise 0.5 mm increments — you can effortlessly switch from delicate, precise lines to smooth shading and bold, solid packing. This wide adjustment range makes the Adjust capable of replacing several different machines, performing perfectly in any tattooing style. 

Its versatility is further enhanced by the two batteries included in the set. The lighter, smaller battery is perfect for detailed work and shorter sessions — reducing hand fatigue and increasing control. The larger battery delivers long, stable power for big, demanding pieces. Thanks to this duo, the FK One Adjust adapts exactly to your workflow, no matter the technique, style, or session length. One machine. Total flexibility. 

Operation is as intuitive as it gets. The responsive touch display works even with gloves, letting you adjust voltage and settings without interrupting your flow. The powerful motor provides consistent, stable performance, while the redesigned anti-roll cap keeps the machine secure on your workstation. 

The Adjust is also compatible with disposable Ergo Shield grips, adding extra comfort and hygiene — especially during long sessions. Both batteries can be conveniently charged using the included charging station, so your machine is always ready to go, no matter how busy the day gets.
