Candela Laser FAQ: VBeam vs Cynosure, Consumer Laser Cutters, and the Best Laser Welder for Small Shops

If you're comparing medical and industrial laser systems—or just trying to figure out whether a VBeam, a consumer laser cutter, or a handheld welder is the right buy—this FAQ is a shortcut. I've spent most of my career on the operations side of laser sales, support, and emergency deliveries. Not as a salesperson. As the person who gets called when something breaks a day before a deadline. These are the questions I actually hear from buyers, answered straight.

What is a Candela laser?

Candela is one of the older names in laser technology, and today it covers two product families that share an engineering approach but are bought very differently. On the medical side, it's one of the most established aesthetic laser brands—VBeam, GentleMax, Nordlys, and Picoway—used by dermatologists, med spas, and plastic surgeons. On the industrial side, the same design philosophy shows up in CO2, fiber, diode, UV, and MOPA systems for engraving, cutting, marking, and welding.

The reason this matters: when someone says “Candela laser” in a quote, I need to know which family they mean. There are also cheap imported devices online that use the name as search bait. They are not the same machine. A medical laser has FDA clearance, calibration requirements, and clinical workflows. An industrial laser has duty cycles, ventilation requirements, and fixturing. The buying criteria are almost completely different.

What is the Candela VBeam laser used for?

The VBeam is a pulsed dye laser. Its target is hemoglobin, which makes it a workhorse for vascular lesions—port wine stains, spider veins, rosacea, and certain scars. According to the FDA's 510(k) database (accessdata.fda.gov), it is cleared for dermatological vascular indications. The advanced VBeam Perfecta adds subpulse technology to reduce bruising and downtime, which is why it's common in cosmetic dermatology.

Still, the common mistake is lumping it in with hair removal lasers. It's not that laser. VBeam works around 585–595 nm; hair removal uses longer wavelengths that hit melanin. If a clinic tells you they're using VBeam for hair removal, that's a sign to ask more questions. For buyers, VBeam is a specialized platform, not a multi-purpose workhorse.

Candela laser vs. Cynosure: which is better?

Short answer: it depends on what you're treating. Candela's clinical sweet spot is vascular and pigmented lesions plus hair removal—VBeam, Picoway, and the GentleMax family. Cynosure is known for PicoSure, SculpSure, and Cynergy. Neither brand is broadly better; the right choice depends on case mix, patient demographics, and your service region.

Here's the question nobody wants to ask first: where is the service technician located? In my experience, a strong platform with slow support is worse than a mid-tier platform with a fast, local engineer. Ask each manufacturer for the local install base and average response time. Both companies have strong training programs, but the quality varies by territory.

Also ask for a demo on your own patient—or at least a detailed treatment protocol. I have mixed feelings about brand comparisons: I've watched clinics buy a spec-sheet winner and then struggle with handpiece availability. Specs are useful. Clinical training and service are what keep the system running.

What is the best laser welder for a small shop?

For most small fabrication shops, a handheld fiber laser welder is the best place to start. As of March 2025, entry-level 1.5 kW handheld welders from established suppliers are roughly $5,000 to $18,000 depending on brand, service package, and accessories (based on supplier quotes; verify current pricing). A 2 kW unit gives more penetration on thicker stainless steel, but the extra weight and price can be overkill for light repair work.

Don't buy on wattage alone. The questions that matter: how long can it weld continuously before thermal shutdown? What's the duty cycle? Is the wire feeder reliable? Can you get a spare contact tip locally? The best welder is the one that can be repaired within 48 hours. In 2024, a local shop called me on a Tuesday with a failed welder and a $15,000 railing contract due Friday. We didn't fix it in time. We found another shop willing to loan theirs. That reshaped how I advise buyers: before you order, ask neighboring shops what they use and whether they'd rent you theirs in an emergency.

Can a laser cutter cut chain?

Yes, but with a caveat: fixturing is everything. If by “chain” you mean decorative jewelry chain, a galvo fiber laser is the standard tool for cutting many small links quickly. If you mean heavy steel chain, a pulsed fiber laser can make clean cuts, but chain movement is the problem. A round link rolls under the beam, so you need clamps, a V-block, or a slower pass with lower power.

For thin steel chain, a 30W–100W MOPA fiber laser can mark and cut small links. For thicker hardened chain—think security chain or lifting chain—you're looking at 1 kW or more. There's also a metallurgy issue: laser-cut hardened steel can have an edge that is harder to machine afterward. Sometimes a cutoff wheel is the better choice. Test on the exact chain before quoting the job.

What should a first-time buyer look for in a consumer laser cutter?

Consumer laser cutters are compact CO2 or diode units aimed at makers and small businesses. They can be a smart way to test a new product line without committing to a 4x8-foot industrial bed. I'm not one of those people who looks down on small orders; some of my best clients started with a $200 engraving job.

Here's the thing: sticker price is not total cost. First-time buyers often compare wattage and completely miss air assist, exhaust, cooling, rotary attachment, software fees, and ventilation. In our tests of sub-$1,000 machines, add-ons pushed the real cost 30–40% higher. A cheaper machine with bad air assist will char wood and create more cleanup time. You don't need the most expensive unit, but you need one with decent optics, a sealed enclosure, and a clear path for replacement parts. Safety is the part people skip: an enclosed cutter with a filtered exhaust is not a luxury if you're using it indoors.

Is a used Candela laser a smart deal?

It can be, if you do your homework. Used VBeam and GentleMax systems often sell for 30–50% below list. But the purchase price is only the beginning. Medical lasers need calibration, cooling maintenance, and handpieces that degrade with use. The same applies to industrial systems: a laser source is a consumable with a rated lifespan, and tubes in CO2 systems have a finite gas fill.

I still kick myself over a deal we evaluated in 2023: a used system priced at $28,000, plus $4,000 shipping, and the first repair estimate was $9,000. The seller couldn't provide a service log, so we walked away. Ask for the original purchase date, service records, and a preventive maintenance certificate. If the seller isn't an authorized dealer, treat that as a risk, not a discount.

How do I choose a laser when I have a tight deadline?

When I'm triaging a rush laser purchase, I ask three questions: how many hours are actually available, is the machine in stock and can it be installed within that window, and what is the worst-case failure cost if it does not work?

Expedited freight can move most laser systems across the U.S. in 2–3 days. But a machine that arrives on time and sits uninstalled is wasted money. In March 2024, we shipped a replacement laser overnight—$1,200 freight—after confirming the local technician could install it the next morning. That install was the difference between keeping a clinic's schedule and canceling fourteen procedures.

For smaller clients, the same logic applies. A rush order for a $500 engraver is still business-critical to the person who needs it. Small doesn't mean unimportant. It means potential.
