Discover the Wireless UNI-B machine from AVA, designed to offer unrivalled precision and performance, this tattoo gun machine stands out for its elegant design and cutting-edge technology.
The adjustable stroke from 2.5 mm to 4.5 mm offers total flexibility with no limits in between. Whether you need a stroke of 2.6 mm or 4.2 mm, you can fine-tune your machine, allowing every movement to be perfectly adapted to your specific needs.
Its high-speed motor, capable of reaching 10,500 rpm, guarantees unrivalled power, allowing the needle to penetrate the skin with ease, even at low voltage.
The AVA UNI-B machine is equipped with an intelligent synchronisation function that saves your data even when you change the battery. Resetting the timing is simple, just hold down the "+" and "-" buttons for 3 seconds. With its replaceable Lithium-ion 18500 battery and state-of-the-art circuit protection measures, this machine ensures maximum safety, even in the event of a battery installation error.
Its display shows crucial information at a glance: voltage, hertz, timer, and percentage of battery remaining.
The UNI-B machine has a brand new function for its high-definition colour display: it's a real assistant. The screen changes colour according to the voltage used, allowing you to visually identify the settings in an instant: green (4.5v-6.9v), blue (7.0v-8.9v), orange (9.0v-10.9v) and red (11.0v-12.0v).
Never be caught unprepared when charging this machine. When the battery is low, the Lightning icon flashes to remind you that it's time to recharge. This is a simple but essential feature, to ensure you never run out of battery during a session.
