What materials and jobs can the DaDo weld?

It is ideal for re-tipping, prong repairs, ring resizes, watch case fixes, glasses frames, and dental fixtures, working across gold, silver, platinum, steel, and costume alloys.

Do I need argon gas to run the DaDo?

No. Argon gas is only needed if you are welding titanium. For gold, silver, platinum, and steel, standard air operation is fine.

What routine maintenance does the DaDo require?

Virtually none. The cooling system uses deionised water and requires very infrequent top-ups. The only consumable item is the flash bulb.

How do you adjust the spot size on the DaDo?

Spot size is adjusted manually using a sliding scale from 0.2mm at its smallest up to 1.5mm at its largest.

DaDo Laser Welder Specs, Running Costs & Applications | Freeform Fabrication

The original DaDo laser welder revolutionized the industry by bringing precision micro-welding within financial reach of small workshops, independent jewellers, glasses repairers, and dental labs. Here is a breakdown of its features, specs, ongoing running costs, and real-world application examples.

Key Features of the DaDo

Designed specifically for tight workshop spaces, the DaDo packs commercial-grade welding capabilities into a ultra-compact footprint:

Ultra-Compact & Portable: Measures just 34cm x 34cm x 34cm, sitting comfortably on standard workbenches without requiring heavy dedicated machinery stands.
Versatile Applications: Handles re-tipping, claw/prong repair, ring resizing, glasses frame repairs, watch case restoration, and dental fixture assembly (including silver welding).
12 Power Settings: Simple control via internal chamber dials or via the free mobile app for iOS and Android.
Low Maintenance Cooling: Built-in internal cooling system engineered for hassle-free daily operation.
2-Year Warranty & Trade-In Protection: Covered by a full 2-year warranty and backed by Freeform Fabrication’s growth plan if you ever upgrade to a larger laser.

Technical Specs & Running Costs

Freeform Fabrication product specialists Beth and Matt answer the core technical questions about owning and operating a DaDo:

Spot Size Adjustment: Manual slider offers precise beam diameters from 0.2mm (pinpoint tacks) up to 1.5mm (smoothing welds).
Consumables: Highly economical—the only ongoing replacement part is the laser flash bulb, which typically lasts several years (millions of shots).
Argon Gas Connection: Pre-installed connection included. Argon is optional and only required when welding titanium.
Cooling System: Requires standard deionised water with minimal top-ups needed over time.
Fast Delivery: Typically dispatches in 1 to 4 working days when in stock.

Case Study: Why Orthodontal & Dental Labs Choose the DaDo

Historically, laser welding was restricted to massive industrial production laboratories. Dental lab Sitha Designs uses the DaDo to produce premium orthodontal appliances faster and at lower costs than traditional methods allow.

Replacing messy traditional soldering and spot-welding, laser welding provides pinpoint accuracy, eliminates solder contamination, and drastically reduces post-weld cleaning and polishing time—saving money on every appliance produced.
