Description
This is a wireless pen-style tattoo machine with a fixed 3.0mm stroke, featuring a 6061 T6 aluminum body made in the USA.
The FK Irons ONE Wireless (Stealth) is a wireless pen-style machine compatible with Cheyenne-type cartridges. With a fixed 3.0mm stroke, it is designed to be an all-around machine suitable for everything from linework to shading. The color is Stealth, combining a matte charcoal finish with a ruby end cap. The body is made from medical and aircraft-grade 6061 T6 aluminum, offering both lightness and rigidity.
It uses a Panasonic NCR 18500A lithium-ion battery, and a 1/4-turn quick-change hatch allows for battery replacement during a session. The output can be adjusted from 5 to 12V in 0.5V increments, and an LED color indicator shows the current voltage. Continuous operating time is up to approximately 8 hours (variable depending on voltage and cartridge size). It includes an eFest dual-slot charger and two batteries, allowing for continuous operation with a spare battery while charging.
