Weld · mark · cut
This jewelry laser welder comparison starts from how most benches are equipped, machine by machine: a welder, a marker and a cutter, each with its own supplier, cooling, software and place on the floor.
The M3 puts welding, MOPA marking and thin sheet cutting into one 300 × 340 × 320 mm, 30 kg air-cooled cabinet.
In summary
300 × 340 mm
That footprint already includes the cooling, which is air moved through the cabinet.
Fiber converts above 30% of input to light against about 3% for lamp-pumped YAG, so the cabinet cools itself with air. The routine consumable is the protective lens.
Both programs run on one 10 inch Android touchscreen. Welding starts from a material dial, and the camera image is on the same screen, so an apprentice learns from it and a customer can watch the repair.
Against the market
In a jewelry laser welder comparison, buyers usually hold one of three machine types against the M3. The rows below decide how a bench runs. A dash means we hold no public figure for that cell.
 M3 | Compact European welder | Black mini YAG welder | White 200 W desktop YAG | |
|---|---|---|---|---|
| Functions | Welding, marking and engraving, thin sheet cutting | Welding only | Welding only | Welding only |

How to read this jewelry laser welder comparison: the compact European welder is the smallest, lightest machine in the table and carries the highest welding peak, and it welds only.
Both YAG types weld only and stand with water cooling. The M3 is the one column that covers welding, marking and cutting and needs no water. Next to any of the other three, the marker and the cutter still have to be bought, placed and learned.
Categories refer to machines such as DaDo (Elettrolaser), Riselaser YAG welders and common 200 W desktop YAG units. Figures from their public product pages, September 2026.
How the work runs
An ordinary custom order: a silver name pendant to engrave, a clasp to weld on and a small tag to cut from sheet, walked through both setups step by step.
3 machines3 programsup to 3 operators
1 machine2 programs, 1 screen1 person
The M3 has two heads and two programs, so the operator switches program once, and the piece never leaves the work area. Grouping the day's marking and cutting into one block and the welding into another keeps that to once per batch.
For distributors
Welding, MOPA marking and cutting in one 30 kg air-cooled desktop cabinet is a product your market cannot buy from the single-function brands. Cooperation runs as OEM, ODM or SKD.
Dimension 1
A separate welder, marker and cutter means three suppliers who each specify their own machine, and none of them checks that the three fit together on your floor.
The screen travels in a metal case and the machine in high strength foam. Distributors who exhibit can have the crate sent straight to the trade show site.
Dimension 2
A multi-machine bench is laid out around its biggest pieces and the services each one needs, plus walking space between stations.
The M3 takes one 300 × 340 mm position with its cooling included. The extraction and cutting fixture join it only on days that include cutting. On a counter it can sit where customers see the work being done, which a welder with a chiller rarely can.
Dimension 3
Three machines mean three interfaces, a welder panel or app, a marking program on a PC and whatever drives the cutter, and knowledge that sits with whoever runs each one.
When that person is off, the machine waits. On the M3 the same two programs run on one screen for every operator, so a second person can cover welding, marking and cutting after one training.
Dimension 4
A lamp-pumped YAG welder is maintained around its lamp and its water, and a marker and a cutter each add their own lenses and service. The M3 has no lamp and no water loop; its fiber sources carry a rated life above 100,000 hours.
The lens keeps spatter off the optical path and is changed at the bench.
Dimension 5
Every machine on a multi-machine bench needs its own supply, and a YAG welder's chiller or pump needs one too, so the bench has to be checked for several loads before anything is installed.
The M3 runs every function from one single phase socket.
A voltage regulation stage on the main board holds pulse energy steady, added after bracelet welds failed on unstable energy for a customer in Istanbul in 2021.
Dimension 6
With three machines from three suppliers, every fault starts with a question before any repair: whose machine is it?
Fault → whose machine is it? → supplier A, B or C → each with its own warranty and hours
Fault → one contact → the people who built the power supply and the QCW source. Describe the fault or send a photo, and the reply comes from the team that designed the part, with no hand-off between a welder brand, a marker brand and a cutter brand.

The conclusion of this jewelry laser welder comparison: the M3 suits shops that do more than one laser job on small pieces and want those jobs on one bench.
Jewelry stores with a repair counter that also engrave, short on space, working in view of customers.
Independent repair shops that weld daily and want engraving, logos and cut pieces as paid services without two more machines.
Custom and personalization studios where one order needs marking, cutting and a weld.
Permanent jewelry businesses and small workshops with no plumbing for a chiller.
Factory sample rooms and aftersales desks handling mixed jobs in small quantities.
Distributors who want a differentiated 3-in-1, with interface and logo in their own brand through OEM, ODM or SKD.Choose a dedicated single-function welder if
