Most people looking for an easy to use jewelry laser welder have never run a laser. They run a repair bench, a goldsmith’s bench or a personalization studio, and they arrive with three questions. Three questions, three answers in full.
Air cooled with no external chiller. A single phase supply. A 10 inch Android touch screen instead of a separate computer. It stands on a corner of the bench already there.
Question one in fullA material dial loads a preset at one touch. A foot pedal fires it, red light positions the marking side, and a 10X binocular microscope reads the first shot before the real piece goes under the head.
Question two in fullOperating and maintenance videos on the machine’s own screen. One routine consumable, changed at the bench. A self check order that names which setting to move first.
Question three in fullQ1 · What has to change
Before a laser can be easy to run, it has to be possible to install. What makes one hard to live with in a jewelry shop is rarely the welding. It is the equipment that arrives around the welding.
The M3 is air cooled. No external chiller, no water to fill, no circuit to bleed, no hoses across the floor, nothing to drain before a cold weekend. The water side of ownership is absent, not simplified, and the back of the cabinet is a vented panel.
The 10 inch 1280P capacitive touch screen runs Android, and both interfaces, welding and marking, live on it. No laptop connects to change a setting. Files reach the machine over Bluetooth, Wi-Fi or USB.
It takes a corner of an existing bench, and one person moves it when the bench gets rearranged. The phone beside it in the photograph is the honest scale.
Built around single phase AC 220 V at 50 Hz, drawing 2 kW in total. Send the single phase voltage and frequency at the socket where it will stand, plus the plug standard in your country. The answer comes back against that socket, not an assumption.
This screen exists because of a customer. A buyer in Denmark reported that a blurred low resolution screen was tiring their eyes across a day at the bench. The Android screen and the imported camera on this machine came out of that complaint.
The whole machine on the home pageQ3 · Where the manual lives
Operating and maintenance videos are inside the M3, on the same 10 inch screen that runs it. The useful part is not the videos. It is where they are.
An unsure operator is standing at the machine with a piece in hand. The interface, the microscope, the dial and the instruction sit on one surface, within reach at that moment.
Nothing depends on a printed manual written for a different model, a good connection that morning, a time zone lining up, or anybody at the factory being awake.
The second and third operators learn exactly the way the first did, from the identical screen. Nobody in the shop has to become the person who remembers how it works.
English and Chinese are on the machine. Other languages are built on request.

Q2 · What there is to learn
What makes a laser hard for a beginner is the size of the thing to be learned. On some machines that is a library of stored recipes, searched before it can be used. Here it is one dial and one shot.
Four positions on the screen: GOLD, STEEL, TITANIUM and SILVER. One touch loads the preset behind the position picked, and the machine is ready to fire from the pedal. That is everything a new operator needs to start.
Each one moves the result in one direction, which is what makes three a learnable amount.
Platinum, copper and aluminium are all weldable on the M3 and none has a position of its own. Start from the nearest position and correct on the first shot, read under the 10X binocular microscope before the real piece goes under the head.
The skill on this machine is reading a result, not memorising numbers.
Q2 · The handover
The real test is not the owner running it. It is the owner handing it to somebody else without standing behind them. Most repair shops have exactly one person for the difficult work, and every job queues behind them. Here the handover has a shape, in six steps.
The camera view and the eyepiece view are the same view, and the screen carries it in HD at a size two people read together. The trainer sees what the trainee sees, and corrects a placement before the pedal goes down instead of after.
The trainee works through the on board videos standing at the M3, with the trainer free to be elsewhere in the shop.
GOLD, STEEL, TITANIUM or SILVER, one touch, nothing adjusted on the first day. An untouched preset is a known state, and a known state is what a beginner needs to learn what the machine does at rest.
Offcuts of the same alloy and section as the real work, never customer pieces, until the trial shot comes out the same way three times running. That first pulse read under the microscope is the one habit carried into every job afterwards.
The natural first set is chain and jump ring repair, bead re-seating, porosity filling and finding work, where the joint is big enough to place a melt point accurately from the screen. The bench owner keeps stone-set work, hollow sections and anything coming back from a previous repair.
The trainer inspects the joint under the camera at the end of the run instead of taking the trainee’s word. The record of what was used, which preset, which spot, which pulse settings, stays in the shop, so the next person starts from a written sheet.
What this changes is the queue.
A second person on the routine half of the repair tray releases the bench owner for the work only they can do. None of it needed a course or a visiting engineer. It needed a shared view and a starting state one touch away.
Q1 · The day it lands
Opening the crate is the first thing anyone does with this machine. Three things travel with it, and each has a job on the day.
Every power supply, every laser source and every assembled machine is inspected individually at the last of four production stations. The checklist names the unit standing in front of you, not the model in general.
The machine is photographed and filmed before the crate closes, so the condition it left in and the condition it arrived in are both on record.
For the step that follows almost every repair. It ships with the machine, not as a later order.
Stand it on the bench and connect it. No chiller to plumb in and no computer to pair, so the gap between opening the crate and firing a trial shot on scrap is short.
Q1 + Q3 · Two documents
Two documents decide how much of this machine you are allowed to understand. Both are handed over, not held back.
Ask for both before you order, not after.
Request the drawings| Document | The day it is for | What it settles |
|---|---|---|
| Installation drawings | The day it lands | How the machine stands, what it connects to, where the vented panel needs clearance, where power comes in and gets isolated. They are also a check on the seller: drawings showing how to open a machine and what is inside it are not something a reseller holds. |
| Repair guidance | The day something needs attention | What is owner level work on this machine and what is not. That single distinction decides whether a problem costs an afternoon or a week. Changing a protective lens is on the near side of it. Opening a source is not. |
Both arrive as a matter of course, not withheld to protect a service revenue stream. A machine you are allowed to read about keeps running in a country with no engineer of ours in it.
Q3 · The one consumable
It sits between the work and the optics that focus the beam, as the cheap thing that takes the damage. Welding throws spatter and metal vapour upward off the joint, and it lands on a flat piece of glass instead of the focusing optics. Sacrificing that glass is the design.
Check the lens before any parameter is touched.
Read your own results, not the calendar. Same preset, same alloy, same section, same settings, and the weld is quietly not what it was: the pool a little smaller, a second pass where one used to do.
A fogged or pitted lens attenuates and scatters the beam before it reaches the work, so a good machine looks like a failing one. Heavy, spattery work uses lenses faster than occasional fine repairs, so change it by the work and by what you see in good light:
It is a consumable, the way a saw blade is, and the exclusion is stated here instead of discovered later. What matters is the length of the list it is on.
One entry is why a year of ownership contains no scheduled service event at all.
Q3 · What is left to do
Most routine maintenance on a jewelry laser is water maintenance. Air cooling removes that list instead of shortening it. None of it is a reduced burden here. It is absent.
Absent with the water
What is left
>100,000 h
Rated life of the laser sources. Read the noun in that figure: it rates the source. It is neither a machine life nor a term of cover. It does say the source is not a scheduled replacement item the way a lamp is.
Q3 · The day it comes out wrong
Almost everything called troubleshooting on a jewelry laser is not a fault. It is a result that came out wrong: a weld that did not take, a mark too faint, an outline that did not go through the sheet.
The machine is working. Something between the file, the fixture, the settings and the glass is not. The order is the same every time, and every step is done at the bench.
Confirm the piece is at the working position and in focus: the microscope on the welding side, the red light outline on the marking and cutting side. A piece that has shifted, sagged or sits off focus produces exactly the symptoms people blame on power.
Two surfaces that are not touching cannot be joined by energy alone, and a heavy section against a heat sink behaves differently from one held in air. On thin sheet, flatness through the cut is the fixture’s job.
Confirm the loaded position is the nearest one to the alloy actually in your hand. Platinum, copper and aluminium have no position of their own and are corrected by eye from the nearest.
More penetration is a different control from how gently the energy is delivered, and a wider spot spreads the same energy over more area. Change one thing, fire on scrap, read it under the microscope, then change the next. Two changes at once tell you nothing.
Inspect it in good light. Replace it if it is hazed, pocked or burned, then repeat the trial shot.
The order has gathered exactly what makes a useful message: the metal, the section, the preset, the three settings, what you changed and what it did.
Send the Six LinesQ3 · Who owns what
The self check order is also a map of who owns what, which is the thing most people want to know when a machine misbehaves.
Yours · at the bench
Ours · component level
The laser power supply and the QCW fiber source are designed and built in house, not bought as modules and integrated. A question that turns out to be electrical or optical reaches the people who drew it, instead of stopping at the edge of what an integrator knows.
If the order ran out, that is the boundary.
It is not a judgement you make alone. Nothing on this page asks you to open an assembly, and nothing asks you to diagnose a source.
Q3 · The cover
Two years on the laser source, one year on the machine, lenses and consumable parts excluded. The same three lines sit on the specification and the configuration sheet. Here they are read against the three kinds of event a working shop actually sees.
| Event | What it is in a shop | Cover |
|---|---|---|
| Consumption | The protective lens, and in normal running only the protective lens. It is meant to be used up, it is cheap, and it is bench work. With one entry on the list, this whole category is nearly empty. | Excluded by design |
| A component | The power stage and the source carry the serious current and the serious optical load in this cabinet. They are also the two things built in house, which is why the source carries the longer term. | 2 years on the laser source |
| The machine around them | The screen, the observation system, the cabinet and everything assembled at the third station. | 1 year on the machine |
No lifetime warranty is offered, and none is claimed.
A term that long on a machine with consumable optics and years of daily use would not mean anything. The excluded parts would surface at the moment the cover was needed.
The manual is on board. The consumable is one part. The document that says what you may open is in the crate.
Ask for the DrawingsQ2 · Before you own it
The fastest way to find out whether you can run this machine is to watch it run your work before you own it. Send one piece: the repair you do most often, a blank in the alloy you find difficult, or an offcut of the sheet you want to cut.
Your first parameter sheet.
On the day the machine arrives, the operator has a known good starting point for the job the shop does most, in its own metal, instead of a blank dial and an afternoon of guessing.
Maximum weldable section, smallest part and sheet thickness are not published figures, because one number would be wrong for half the pieces quoted against it. A piece beyond what an M3 will do comes back saying so, along with what could not be achieved on it.
All three · blank on purpose
Some of what a support page usually promises is missing from this one deliberately. These are the four, with the reason and what is stated in their place.
| Not quoted | Why it is blank | Stated instead |
|---|---|---|
| Training duration | No course length, no session count, no claim about minutes to get started. That figure depends entirely on who is standing at the bench and what they already do for a living. | What is in the machine and what is in the crate. Both are checkable. |
| Response time, an engineer at your door, spare part delivery | The M3 is sold direct and internationally, and each of those would be a different figure in every country. | A machine that needs the factory less: the manual on board, one consumable you fit yourself, and the document that says what you may open. |
| Failure rates, a fault code table, a common faults list | All three would have to be invented, and a jewelry shop would plan around them. | The self check order, and a message format that gets a real answer. |
| Retrofit of a major assembly | Some changes can be retrofitted to a machine already on a bench, and some cannot. | Which one, said plainly when asked. |
Two ways to start
Ask for the installation drawings and the repair guidance, and read what running this machine involves before buying it. Or send one piece of your own work and get it back with the settings written down.
