Cannot draw it
Everything falls on the bought side.
The line exists, but nothing sits on the left of it. Ask which parts were designed in the building you are writing to, and the answer is a supplier list.
The line we draw
The Jewelry Laser Welder Manufacturer Behind the M3
Here is the line, drawn where you can check it. We design and build the laser power supply and the QCW fiber source inside the M3. The camera, the IGBT, the optics and the switchgear are bought, and this page says why.

A trading company cannot draw this line. An assembler draws it around the cabinet.

What the line separates
Two Parts a Jewelry Laser Welder Manufacturer Owns
Two things in an M3 are ours from schematic to finished assembly, and they are the two parts a trading company cannot describe in any detail.
Made here
Laser power supply
The unit that feeds the QCW source, with the Infineon power stage on it. Drawn here, which is why a fault in it is diagnosed at board level rather than by swapping a module.
QCW fiber source
The source that does the welding, built and coupled here. A jeweler meets the result as a spot that behaves the same way every time the foot switch goes down, on the two hundredth pulse as on the first.
Bought in, and named
Sony observation camera
Because the image is what the operator aims with.
German Infineon IGBT
Because the power stage is where the heat accumulates.
Quartz optics, optimised coating
Because the protective lens has to survive the work.
Schneider switchgear
Because switchgear with a name on it is not worth reinventing.
The specification sheet says the same thing this page does. Read the specification sheet
Reasons, not a parts list
The Bought Half, Named Part by Part
Every part on this list is bought because buying it is the better engineering decision, and each argument is short enough to check.
- German Infineon IGBT
- The power stage runs hot and runs long. That is not a place to save money.
- Sony observation camera
- What the operator sees through the microscope decides where the pulse lands. A dim, soft image is how a weld ends up in the wrong place.
- Quartz optics, optimised coating
- The protective lens is the one consumable on this machine, so it should last. Quartz with an optimised coating rather than K9 keeps it a bench job.
- Schneider switchgear
- A solved problem with a known name on it. What is unusual is a supplier telling you which half of the machine is which.
One question, three answers
Jewelry Laser Welder Manufacturer, Assembler, Trading Company
Ask every supplier on your shortlist to draw the same line through their own machine. Where they put it tells you what they are.
Assembler
Draws it around the cabinet
The box is theirs. The source is not.
Modules go in, a badge goes on. A fault inside a bought module is diagnosed by swapping it, which is why the machine has to travel.
This factory
Around the supply and the source
Two parts made. Four parts named.
The power supply and the QCW source are ours. The rest is bought and said out loud, the only version of this answer you can check against a specification sheet.

Product line, one bill of materials
The arithmetic behind it
One Product Line, One Bill of Materials
Developing a laser power supply and a fiber source in house is expensive, and it only pays back if everything you sell uses them. A company with twelve models buys modules instead. That choice is arithmetic, and the buyer inherits the consequences.
Parameters
If your source is a bought module, your parameter set is whatever the module exposes. If you built it, the pulse behaviour is something you can change.
Diagnosis
A failure inside a bought module is diagnosed by swapping it, so a large assembly ships out. A failure inside a power stage we drew is diagnosed at board level, by people who have the drawing.
Both of them visible
Two Trade-offs Visible on Your Bench
- Air cooled, no external chillerA 30 kg cabinet stays on a jeweler’s bench and the water circuit disappears as a maintenance item.
- One product line, not a catalogueThe narrow range is what pays for the source and the power supply being ours. Both decisions sit in the machine on your bench, not in a claim.

Where a machine can be stopped
Four Stations Between Components and a Packed M3
An M3 passes four stations, and each one has a name because each one is a place where a machine can be stopped.
Power supply assembly
The station that exists because the power supply is ours: the unit that feeds the QCW source, with the Infineon power stage and the voltage regulation stage on it.
Stops a machine whenA regulation stage reads outside its window on the bench test, and no source is coupled to it until it does not.
Laser source assembly
Where the QCW fiber source is built and coupled. Coupling decides beam quality, and beam quality is what reaches the bench as a spot that repeats.
Stops a machine whenA coupled source will not hold its spot across a run, which is caught here rather than in your workshop.
Final assembly
The cabinet, the 10 inch Android screen, the microscope and camera, the welding head and the galvo head, the air cooling and the wiring, built in the order you will meet them.
Stops a machine whenTwo heads, one cabinet and one screen do not come up together on first power.
Unit-by-unit inspection
The only station whose job is to reject the work of the other three. Who signs, and where rejected work goes back to, is the part that matters.
Stops a machine whenAny line on the checklist is unsigned. The crate does not close on a sheet with a gap in it.
The picture establishes the shell. The four station names establish what goes on inside it, and that is the part worth reading.
Inspection does not report to assembly. That is the only arrangement under which it can send work back.
The fourth station
The Signature at the Last Station
Not a sample from the batch, not the first one off the run. Each unit goes through one at a time against a Quality Inspection Checklist.
- Every power supply, tested
- Every laser source, tested
- Every completed machine, tested
The sheet in your crate is the sheet somebody signed for your serial number, not a template reprinted for the batch.
A failed unit goes back, not forward
It returns to the station that owns the fault, the fault is fixed there, and the machine is inspected again from the top of the sheet rather than the line it failed on.
The same line failing twice is a build problem
If a line on the sheet fails on unit after unit, it goes to the people who drew the thing rather than the people who assembled it.
Four kinds of work
The People at the Four Stations
The electronics and optics people who build the power stage and couple the source are the same people who answer when a support question turns out to be about either.
Electronics and optics
Power supply and source. Reachable through support rather than sealed off behind somebody else’s parts list.
Mechanical and electrical fitting
Final assembly. The machine you will actually use is put together here, in the order you will meet it.
Inspection, reporting separately
A separate role, for the reason above. Engineering sits across all four, because a drawing change has to be walked to the bench that builds it.
What a report is able to change
From a Customer Video to the Build
Every supplier collects fault reports. The difference is what a report is able to change. With one product line a fault cannot become a note against a future model, because there is no future model waiting to absorb it.
A phone video arrives
A description and a video, taken at a bench with the screen visible.
Reproduction here
The same job, the same metal, the same settings, on a machine here.
The cause is found
Named to a stage or a part, not to a symptom that has to be escalated.
One of two things changes
Either the design changes, or the inspection sheet changes.
The checklist changes more often than people expect
Many faults are not a part that is wrong but a condition nobody was checking for. A new line on the sheet catches it on every unit from then on, which is why the inspection sheet grows rather than staying the document it was two years ago.
It lands on the same bill of materials
The next machine is built from the list the change went onto, and no fix is held back as a feature for a successor.
The other branch
A Fault That Will Not Reproduce
Not reproducing usually means something at your bench is different from this one, and three things account for nearly all of it. Nothing changes in the build on a report we could not reproduce, because a change made on a guess is a change nobody can inspect for.
- Mains supplyWhat the socket actually delivers under load.
- Working environmentTemperature, humidity and what sits next to the bench.
- How the piece is heldWhere the heat goes once the pulse lands.
The machine you already own
The Machines Already on Benches
A company that improves its only machine has to answer for the one somebody bought last year. Three cases, separated honestly.
- A safety or reliability fix
- Handled on machines in the field, not only on machines still to be built. The warranty is two years on the laser source and one year on the machine, with lenses and consumable parts excluded and stated here rather than later.
- A consumable-level change
- The protective lens is the one that matters, and it reaches you as the next part you fit, because the improved part is what we ship.
- A major assembly change
- Honestly not retrofittable in most cases, and we say so instead of implying that every machine in the field is always current.
What we do not do is discontinue your machine. There is one product line, so a part for a machine built earlier is a part for the machine we are building now.
No model number to look up
Jewelry Laser Welder Manufacturer Support
Most equipment support asks which model you have, then which firmware, then transfers you. None of that exists here.
The reply is about your piece
There is one machine, and everybody who answers has worked on it. You describe what the machine did, and the answer is about your parameters, your metal and your piece. A question that turns out to be electrical or optical reaches the people who designed those.
Operating videos live inside the machine
On the same 10 inch Android screen used to run it, in English and Chinese with other languages on request. A new operator learns from the machine in front of them.
One set of spares, not one per model
The part replaced in normal running is the protective lens, and fitting one is bench work. Installation drawings and repair guidance are provided rather than withheld.
Before money changes hands
Three Requests for a Jewelry Laser Welder Manufacturer
Everything on this page is checkable before you order, in the order the requests cost you least.
The installation drawings and repair guidance
We provide both, and providing them before an order rather than after one is the test.
What the answer tells youDocumentation showing how to open the machine is not something a reseller has, and not something a fragile story survives.
A real fault, described
Energy that wanders during a long run of the same weld, or a spot not landing where the microscope says it should.
What the answer tells youA generic reply, a request to return the machine or a promise to escalate tells you one thing. A reply naming a parameter, a stage or a part tells you another.
One piece of your own work
One repair, one blank, whatever you do most often. It comes back with the source, the spot, the pulse settings and the preset written down.
What the answer tells youRead the declines closely. Maximum section, smallest part and sheet thickness stay unpublished, because one number would be wrong for half the pieces quoted against it.
Selling direct, so no layer in between
Every Stage and Its Named Owner
There is no layer between you and the bench, so it is worth saying who handles what.
Enquiry
The sales engineer who stays with it
Their first job is not a quotation, it is working out what you make and repair, because the configuration follows from the work: the MOPA tier, the rotary device, the fixture and fume extraction, and your mains supply.
Sample piece
Run by a person who welds for a living
The parameter record that comes back is written by whoever ran it. Anything the sales engineer cannot answer goes to engineering rather than being guessed at.
Build
Production and the four stations
They take over once a build is confirmed, and the stage ends at the inspection signature.
Dispatch
Packing, photographs and forwarding
Pre-dispatch photographs and video, the forwarder, and one-to-one tracking on VIP orders.
After delivery
The same engineering group
Not a separate call centre, and the sales engineer you started with still knows what you make. That continuity is the argument for buying direct rather than through a reseller who forwards the question and waits.
Boundaries, plainly
Work This Factory Turns Down
A supplier who claims everything is a supplier you cannot plan around. Five things stay off the list.
No catalogue
One machine, one bill of materials. An industrial welding cell or a large-format plate cutter is not us. Three-in-one means weld, mark and engrave, and cut.No figures we cannot stand behind
Sheet thickness ranges and cutting speeds move with metal, temper, artwork and configuration, so they are not on this site. Nor are maximum weldable section, smallest part and sheet thickness.No promise on every stone-set piece
Stone type, treatment, setting and distance from the joint decide that piece by piece, and the assessment lives on the repair page rather than being glossed over here.No claim to beat every machine at every parameter
What the M3 does that the established European welders do not is put repair welding, marking and thin sheet cutting on one bench, in a cabinet a counter can hold.We do not make the camera, the IGBT or the optics
We buy the good ones, and we name them.One machine, improved on one bill of materials.
Send Us a PieceThe second bench
A Second M3 in Three Years
A replacement or a second bench should not be a new evaluation. With one product line it is not.
The parameters transfer
Same source, same power supply, same interface, so an operator trained on one is trained on both and the recipes your shop has built up stay worth something. With multi-model suppliers the second machine is a different machine.
The consumable list does not change
It is the protective lens, a far shorter list than a lamp-pumped welder keeps over the same period. The fiber sources are rated above 100,000 hours, a rating on the source rather than a promise about the machine.
Spares stay in stock
They are the only spares there are. Nothing is discontinued to make room for a new model, and interface changes are versions of the same interface.

Buyers Who Order Direct From the Factory
01Bench jewelers, goldsmiths and silversmithsRunning their own workshops, where the M3 replaces work sent out and the buyer is the operator.
02Independent repair shops and jewelry storesRepairing in house, where 300 × 340 × 320 mm at 30 kg decides whether a laser is possible at all.
03Custom studios, designers and permanent jewelry businessesWho came for marking or cutting and stayed for the welding source in the same cabinet.
04Small workshops and sample roomsWhere the value is one machine covering three processes with parameters that are written down.
Mostly overseas, which is why support is built around a screen you can share over Wi-Fi and documentation you can read before you order.
We publish no customer names, counts or case studies. Nobody has agreed to have their shop used as our marketing, and an invented figure is worth less than the piece you can send us this week.
Two ways to start, both free
Ask for the Drawings, or Send Us a Piece
Ask for the installation drawings and repair guidance and read them. Or send one piece, tell us the job you do most often, and get it back welded with the settings written down.
