PMU Machines

What is the difference between a PMU machine and a regular tattoo machine?

The mechanical principle is the same — a rotary motor drives a needle in and out of the skin — but the tuning is different. PMU machines are built for facial skin, which is thinner, more vascular, and less forgiving of aggressive implantation than body skin. The differences that matter in practice: shorter stroke length (typically 2.0–3.5mm versus 3.5–4.5mm for body work), lower needle speed for more controlled pigment deposit, lighter machine weight to reduce hand fatigue during long precision sessions, and tighter voltage ranges that keep the needle moving consistently at the shallow depth PMU procedures require. A body tattoo machine used for PMU work isn't impossible, but the margin between correct implantation depth and trauma is much smaller on the face — purpose-built PMU machines like the Kwadron Velure, Microbeau Flux S PMU, and Bishop PMU Pen Silver are calibrated for exactly that range.

What stroke length should I use for PMU procedures?

Stroke length determines how far the needle travels per cycle — longer stroke moves more ink and goes deeper, shorter stroke is more precise and less traumatic. For most PMU brow work: 2.5–3.0mm is the standard range. For powder brows and ombre shading where you want faster pigment build: 3.0–3.5mm. For nano brows, fine hairstrokes, and eyeliner where precision is everything: 2.0–2.5mm. For lip blush: 3.0–3.5mm works for most artists. The Cheyenne SOL Nova Unlimited's dial adjustment is one of the reasons it became standard in PMU studios — being able to switch from 2.5mm to 3.5mm mid-session without changing machines is a real practical advantage when a client's skin responds differently than expected.

What is the difference between the Bishop Power Wand and the Bishop PMU Pen?

Two different machines built for different use cases within the same brand. The Power Wand is a heavy-duty rotary machine with a high-torque motor — it handles demanding body tattoo work, long shading sessions, and thick skin without slowing down or losing consistency. Artists who do both body tattooing and PMU often choose the Power Wand as their single machine because it performs across both. The Bishop PMU Pen Silver (Grey Spline and Pink Spline) is a lighter dedicated PMU pen — lower weight, stroke range optimised for facial procedures, built for the kind of precision brow, lip, and eyeliner work where machine weight becomes a factor after two or three hours of use. For studios doing exclusively PMU, the PMU Pen is the more practical daily driver. For mixed studios or artists who tattoo and do PMU, the Power Wand with the right cartridge handles both.

What is the Microbeau Xion S Stroke Wheels Pack and when would I use it?

The Stroke Wheels Pack is an accessory set that lets you change the physical stroke length of the Xion S pen by swapping out an internal cam wheel rather than adjusting voltage or speed on the machine. Most wireless pens adjust effective stroke by changing speed — the Xion S lets you change the mechanical stroke itself, which gives a different feel in the hand and a different result in the skin. Artists who run the Xion S across multiple procedures — brows one day, body shading another — use the wheels pack to dial in the mechanical stroke for each procedure type rather than compensating through speed settings alone. It's a more technical approach to machine setup and it's most relevant for experienced artists who already understand how stroke length affects their specific technique.

What is the difference between the Cheyenne SOL Nova Unlimited 2.5 and 3.5?

The numbers refer to the default stroke length — 2.5mm and 3.5mm respectively. Both machines have the same dial adjustment mechanism, so both can be adjusted across a range from the default. The 2.5 starts at the shorter end and is the more common choice for PMU-focused artists: fine liner work, nano brows, eyeliner, and lip work where a shorter default stroke gives more control. The 3.5 starts longer and is the more common choice for artists who lean toward powder brow, ombre, and body work where faster pigment saturation is the goal. If you do both fine detail and shading work, the 2.5 is the more versatile starting point — it's easier to dial up for shading than to dial a 3.5 down to fine liner territory without losing feel.

What does "adjustable stroke" mean on machines like the Filter X30, EZ EvoTech, and INKIN InkFlexo?

Adjustable stroke means the machine has a mechanism — usually a dial, a twist collar, or a cam system — that lets the artist change the needle's travel distance per cycle without swapping machines or grips. On a fixed-stroke machine, if the stroke doesn't match the procedure, you compensate with speed and voltage, which is indirect and less precise. On an adjustable machine, you set the stroke directly for the procedure you're doing. The Filter X30 uses a dial system; the EZ EvoTech S has a similar rotary adjustment; the INKIN InkFlexo is adjustable and adds the practical advantage of dual batteries, which matters for studios running back-to-back sessions without downtime for charging. For artists working across multiple procedure types in a day, adjustable stroke is the single most useful machine feature after motor consistency.

What is the Microbeau Apollo SMP and how is it different from other Microbeau machines?

The Apollo is Microbeau's dedicated scalp micropigmentation machine, and the difference from the Flux or Bellar lines is in how the motor and stroke are tuned. SMP requires implanting very small, round dots of pigment at consistent depth across a large surface area — the back of the scalp in a full SMP session can involve thousands of individual dot placements. The Apollo's motor is tuned for the short, precise stroke SMP requires and the speed consistency that keeps dot size uniform across a session. Using a standard PMU or tattoo machine for SMP is possible but harder to control — the Apollo removes the variable of adapting a general-purpose machine to a procedure with very specific technical requirements. For studios building or expanding an SMP service, it's the cleaner starting point.

Is the Dragonhawk Mast Tour Nano Y22 suitable for PMU or is it primarily a tattoo machine?

The Nano Y22 is listed specifically as a Wireless Permanent Makeup and Tattoo Machine — it's Dragonhawk's crossover model in the Tour family, designed to handle both. In practice, the Nano designation refers to a compact form factor and the Y22 configuration's stroke and speed range, which sits in PMU-compatible territory. For artists who do brow and lip work but also want a machine that handles body tattooing without buying a second pen, the Nano Y22 is the Tour line's answer to that. It won't replace a dedicated PMU machine like the Kwadron Velure or Bishop PMU Pen for a studio doing exclusively facial PMU, but for a mixed-use artist or a studio just adding PMU to an existing tattoo business, it's a practical single-machine option.
