Sunstone DADO Laser Welder | Affordable Benchtop Laser Welder

The Sunstone DADO: Professional Laser Welding, Finally Within Reach

The most compact, affordable ND:YAG laser welder ever built — engineered by Sunstone's micro-welding experts for jewelers, dental labs, and small shops. Get the precision of a professional benchtop laser welder without the five-figure price tag.

What Is the Sunstone DADO Laser Welder?

The Sunstone DADO is an entry-level ND:YAG benchtop laser welder designed from the ground up to be affordable, compact, and genuinely easy to use — without stripping away the core capabilities that make laser welding so valuable.

Built on decades of micro-welding expertise by Sunstone and Orion Welders, the DADO delivers precision spot welding in a machine the size of a shoebox. At just 14 × 14 inches, it fits on any workbench — in a goldsmith's studio, a dental lab, a jewelry repair store, an R&D bench, or even a hobby shop.

Where traditional professional laser welders can cost $15,000 to $40,000, the DADO makes this technology accessible for the first time to smaller operations that need reliable, clean welds without a massive capital investment.

Laser Welding Without the Learning Curve

Most laser welders come with complicated controls and a steep setup process. The DADO was intentionally designed to be different.

12 straightforward power settings mean there's no overwhelming parameter library to memorize. You select your power level, look through the integrated 10× magnification microscope, and weld. The machine's vocal assistant guides the operator through every step, providing real-time status and feedback so you always know exactly what the machine is doing.

Better yet — setup is as simple as it gets: unbox the DADO, fill the water reservoir for the built-in liquid cooling system, plug it in, and start welding. Most users are making their first welds within minutes of opening the box.

DADO App control takes things further. The machine is operated via a dedicated smartphone app that gives you full control from your phone's touchscreen — no proprietary controller box, no confusing menus. The optic laser status indicator uses variable internal lighting colors so you can see at a glance what mode the laser is in.

Built for Precision. Built to Last.

Don't let the price fool you — the DADO is built with the same robust, industrial-grade construction philosophy that has made Sunstone a trusted name in micro-welding for decades. It's designed to last as long as any laser in the market.

The 0.2–1.5 mm adjustable spot size gives you the flexibility to handle fine jewelry repairs, thin metal frameworks, eyeglass frame repairs, and watch components — all from a single machine. Liquid cooling keeps the system running at stable temperatures even during extended work sessions.

Who Is the DADO Built For?

The DADO excels in light-duty precision welding applications across a wide range of industries. It's purpose-built for:

• Jewelers & Goldsmiths — Repair rings, chains, bracelets, and clasps with pinpoint accuracy, right next to heat-sensitive stones, without the torch damage or fire scale you'd get from traditional soldering
• Dental Labs — Weld implant frameworks, PFM structures, and orthodontic components with exceptional fit and accuracy; reduce costly remakes and lab repair bills
• Eyewear & Watch Repair — Handle delicate frame repairs and small mechanism components with the precision that only a laser welder provides
• Orthodontics — Precise, clean welds on appliances and metal frameworks
• R&D and Prototyping — Fast, clean welds on small metal test parts and assemblies without fixturing complexity
• Hobby & Makers — Work with metals in a creative workshop setting with professional-grade results

"The Dado is probably the best equipment purchase I've made since my first automatic porcelain oven! It's very easy to use, the learning curve is very short, and the accuracy of fit of my welded frameworks (implant and PFM) is astounding. The price, the ease of use, accuracy, and small footprint make the Dado a winner all around! I am very pleased and would HIGHLY recommend this welder."

Weld On the Workpiece. No Defects. No Loss of Value.

One of the biggest practical advantages of laser welding over torch soldering is non-destructive precision. The DADO lets you weld directly on the workpiece — without distorting it, discoloring surrounding metal, or damaging nearby stones or delicate components.

This matters enormously in repair work: a botched torch repair on a customer's piece can reduce or destroy its value entirely. With the DADO, the extremely localized heat-affected zone means the rest of the piece stays untouched. Your repair looks clean, professional, and invisible — and your customer's piece retains its full value.

What's in the Box

The DADO ships fully accessorized and ready to weld — no hunting for missing parts, no add-on purchases required for basic operation. Everything you need to get started is included from day one:

• DADO Laser Welder unit
• All necessary accessories for immediate use
• DADO App (free download)
• Full user manual

Plug it in. Fill the water. Download the app. Start welding.

Which Variant Is Right for You?

DADO Laser Welder — Standard
The right choice if you're confident in your equipment, prefer to manage your own maintenance, and want the lowest upfront cost. Backed by the standard 2-year manufacturer's warranty.

DADO Laser Welder + Sunstone Circle Protection Plan
Choose this if you want the ultimate peace of mind on your investment. The Circle Protection Plan adds a Forever Warranty, a complimentary loaner unit if your machine ever needs service, free replacement coverage, free software upgrades, complimentary shipping on service, and expedited customer support — essentially eliminating the risk of downtime for your shop. This is the smarter choice for businesses where the welder is a revenue-generating tool you simply can't afford to have offline. If the DADO is going into active daily production — even light production — the Protection Plan pays for itself the first time something goes wrong.

Frequently Asked Questions

Is the DADO suitable for a complete beginner with no laser welding experience?
Yes — the DADO was specifically designed with the first-time laser welder user in mind. The 12 simple power settings, vocal assistant guidance, and smartphone app interface make it one of the most approachable laser welders on the market. Most users are welding within minutes of setup.

Can the DADO weld silver?
The DADO is best suited for gold, yellow gold alloys, titanium, and chrome-cobalt — metals common in jewelry and dental work. Welding highly reflective metals like silver typically requires significantly higher peak power than the DADO produces. If silver welding is a core requirement, contact our team and we can help identify the right machine.

How does the DADO compare to a traditional soldering torch?
Laser welding with the DADO gives you a dramatically smaller heat-affected zone than torch soldering. This means you can weld safely next to heat-sensitive gemstones without damage, avoid fire scale and discoloration, and achieve invisible repairs that are impossible with a torch. For any shop doing regular repair work, the DADO typically pays for itself quickly in labor savings and fewer remakes.

What does the smartphone app actually control?
The DADO App gives you full control over the machine's operation from your smartphone's touchscreen — including power level adjustments and operational controls. The vocal assistant provides real-time status updates so you always know what the laser is doing.

Does the DADO require argon gas?
Unlike pulse-arc welders, the DADO does not require argon gas for standard operation. This simplifies setup and reduces ongoing operating costs.

What is the DADO's weld rate?
The DADO fires at 1–4 welds per second, which is appropriate for precision repair and light-production work. For high-volume, continuous-production environments, a higher-powered Sunstone laser welder may be a better fit — our team can walk you through the options.

What's your return policy on the DADO?
We offer a 75-day return window — significantly more generous than buying directly from Sunstone, which offers no cash refunds on the DADO. Please contact our team before initiating a return so we can assist.

Is this covered by a warranty?
Yes — the DADO includes a 2-year manufacturer's warranty from Sunstone. If you purchase the Sunstone Circle Protection Plan variant, you receive a Forever Warranty plus loaner unit coverage, free replacement, and more.

Do you offer financing?
Yes — contact our team to discuss financing options for the DADO.

I have a question before I buy — can I talk to someone?
Absolutely. Call or email us and you'll reach someone with genuine technical knowledge about laser welding — not a call center script.
