Complete guide: Spektra Flux S Wireless PMU Machine Stealth
Spektra Flux S from Microbeau (Fk Irons) is a wireless tattoo machine dedicated to micropigmentation (PMU), built on a silent brushless motor and a 3.0mm stroke. It comes with a swappable battery, rechargeable via USB-C cable, designed to eliminate the power cord from the work area and reduce the risk of cross-contamination. It is intended for micropigmentation artists who work with membrane needles and want a compact device with quick settings from the handle.
How to use
- Fully charge the swappable battery before first use, using the original USB-C cable — very long cables or weak power sources can slow down or block charging.
- Insert the battery into the handle and turn on the device.
- Attach the compatible cartridge/membrane needle, making sure it is securely fixed with no play.
- Adjust the voltage from the color-coded display on the handle, adjusting in half-steps until you find the right setting for your technique and work area.
- If using the Darklab app, pair the machine via Bluetooth to track work time and any firmware updates.
- Test on a small area before moving on to larger surfaces to confirm the chosen voltage.
- If the battery runs out during the session, quickly switch to a spare battery (if you have one) without interrupting your workflow.
- At the end, turn off the device, remove the used cartridge/needle, and prepare it for cleaning/disposal according to your hygiene protocol.
Tips from us
- Keep a second charged battery handy for long sessions — the device is designed for quick swapping without cables.
- Always start with a lower voltage and increase gradually, especially when testing an area or a new needle.
- Use only the recommended standard USB-C cable for charging — long cables or weak power supplies can significantly prolong charging time.
- Periodically check the Darklab app for firmware updates.
- Disinfect the handle after each client, according to your studio protocol.
Warning: This is a reusable device used directly on the client's skin: at each session, protect the handle with disposable barriers, use sterile, single-use needles/cartridges, and disinfect the device surfaces between clients, according to the hygiene standards of your studio. Never reuse the needle/cartridge on another client.
