M3 · Full data sheet
Two 1064 nm fiber sources sit in one cabinet: a QCW source for welding, a MOPA source for marking, engraving and cutting. Every figure below is grouped by the source it belongs to, because a welding number and a marking number on this machine are not comparable to each other.

Machine data
Sixteen rows of jewelry laser welder specifications describing the machine as a whole, independent of which source is firing. Weight, mains supply, the ambient range the machine is rated for and what the warranty leaves out are all on the page, not in the paperwork under the lid.

Two numbers, two questions. 45 kg in a 500 × 520 × 540 mm case decides how the machine reaches you and who carries it through the door. 30 kg is what stands on the counter afterwards, and whether a bench can take it without being rebuilt.
Above 100,000 hours rates the fiber source and nothing else. It is on its own row for that reason, two rows from the cover: two years on the source, one year on the machine, lenses and consumable parts excluded.
A mini ultrasonic jewelry cleaner is listed because it ships in the case, not because it describes the machine. Every other row above it does.
QCWMOPA
Architecture
A QCW source welds. A MOPA source marks, engraves and cuts. Two sources, two heads, two software interfaces, one cabinet, one screen.
That is not redundancy. The two jobs sit in different physical regimes, and neither source can be asked to cover the other by changing a setting.
The cabinet. The single-phase supply. The air cooling. The 10 inch Android screen. The power stage, with its German Infineon IGBT and its voltage regulation stage. And the one routine consumable, the protective lens.
The head. The interface. The working position. That is why the tables below are split by source rather than merged into one column.
Jewelry welding is a sequence of discrete melt points placed by hand under the microscope, each a millisecond-scale pulse fired from a pedal at one to twenty shots per second.
Marking and cutting are a galvo sweeping a beam across a field at 7000 mm/s at 20 to 80 kHz. One source places single shots where the operator is looking; the other traces a path far faster than a hand can move.
No single-source machine has to explain this part, and it is the part a comparison sheet gets wrong most often.

Power figures
The QCW source is specified at 120 W to 1200 W, the machine at 2 kW total. Those two figures look contradictory on a spreadsheet, and they are the first thing an engineer challenges.
They are not contradictory because they measure different things. A QCW source fires for 0.2 to 15 ms at a time, at 1 to 20 Hz.
Multiply the longest pulse by the highest frequency and the source is emitting for under a third of each second at the limit of both settings. Prong and finding work runs short pulses at low frequency, a small fraction of that again.
Average power on a pulsed source is peak power multiplied by that duty. Add the MOPA source at 10 W, 20 W or 60 W, the screen, the camera and the control electronics, and the machine still sits inside 2 kW.
The consequence is on your side of the wall: no three-phase supply to install, no dedicated circuit, and no electrician standing between delivery and the first weld.

The range matters because the same machine closes onto a prong tip and opens out for a finishing pass across a shank seam. The motor matters more: a motor returns to a setting, while a manually adjusted spot is re-found by feel every time. Over twenty identical chain repairs that is one job repeated, not twenty separate judgments.
BPP describes how tightly the beam can be focused and how steeply it falls off at the edge of the spot. On fine work that is what decides whether energy lands on the joint or spreads into the metal beside it.
Pending · foot pedalThese rows say what each figure constrains, not how to set the four of them for a given joint.
QCW
Not on this sheet
No value, no range, no approximation standing in for one.
We have no values we would stand behind across the alloy range, and a table we could not defend on your bench is worth less to you than this paragraph. Welding limits are not one number in any case: the same silver section behaves one way as a solid shank, another as a hollow wall, and differently again beside a stone that has been heat treated.
We answer it on your actual piece. Send the work, or a sample in the alloy and the section you deal with, and we run it on an M3 and send it back with the parameters used. That is an answer about your metal and your geometry rather than a row in a table.

It states how precisely the beam is placed inside the field. Stroke width comes from the beam and the parameters; depth is a parameter choice rather than a fixed property. A machine quoting 0.01 mm accuracy is not thereby claiming a 0.01 mm line.
Beam quality on this side is stated as M² 1.5, the metric used for a scanning beam, against BPP on the welding side. They are two different measures of two different beams inside the same cabinet. Lining them up in adjacent cells and calling one better is the most common misreading of this sheet.
Pending · colour range20 to 80 kHz is how often the source fires and 7000 mm/s is how fast the beam crosses the work. Between them they set how long a filled area takes and how much heat builds under it. That is throughput, not quality.
Pending · tag in fieldMOPAQCW
Where the datum is
Everything that source does happens inside 70 × 70 mm, referenced to the same origin at the same working height. A piece cut in that field is already in position to be marked in it.
There is no scanned area on the welding side at all. The operator focuses through the 10X binocular microscope, holds the piece in both hands and fires from the pedal at whatever point the eyepiece is on. The datum is that focus, not a coordinate.
When a job crosses between the two sources the piece is re-fixtured. No coordinate system carries across from the welding position into the marking field, and we do not claim one.
Before the MOPA source fires it traces the artwork onto the actual piece, at the size and in the position it will be marked, so the operator sees where a serial number lands against the edge of a tag while moving it is still possible. On work just welded, and so no longer quite the shape the file assumed, that is the more reliable datum of the two.

Control and observation
An apprentice works from the screen, not the eyepiece. That one row decides how much a second pair of hands can take.

Energy budget
The size of this machine is the consequence of an energy budget. Follow the budget and five specification lines explain themselves at once.
A fiber source turns more than three tenths of its input into light, against roughly 3 percent on a lamp-pumped one.
Whatever a source fails to turn into light it turns into heat. At 3 percent the cabinet has to shed nearly all of its input.
At 2 kW of input the remainder is small enough for air. The rear panel is the vent wall, and that is the cooling system, complete.
No pump, no hoses, no unit standing on its own floor space with the optics fitted around the water.
The dimension line at the top of this page is the last link in that chain.
The ambient rating comes off the same budget: 0 to 40 °C at 80 percent humidity or below. Air cooling is why that is a working range rather than a formality — an unconditioned back room in a hot climate falls inside it.
So does the maintenance line, empty on the water side because there is no water side. What is left is the protective lens.

Part level
Some specification lines describe what the machine does. These describe whether it keeps doing it.
Decides whether pulse number one thousand matches pulse number one after twenty minutes of continuous high-power work. The cheap part and the good part read identically on any sheet that does not name a brand.
Its job is to keep the energy delivered from drifting between pulses, so that the pulse trialled on a test point is the pulse still being delivered at the end of a run.
Against the K9 glass and ordinary coatings used elsewhere in this class. A durability specification rather than a performance one: how long a coating survives a working environment.
The switchgear behind the single-phase supply row, where a failure is not a performance question but a day the bench does not open.
We build the laser power supply and the QCW fiber source ourselves rather than buying them in, which is why these rows can be specified at all instead of being whatever a supplier shipped that quarter.

Configurations and what shipsMOPA
Configuration
Specified against the pieces you make and the metal you make them in. We publish no recommended tier.
MOPAInside-band engraving is not possible without it, so it is standard kit for that work rather than an extra.
MOPAThe same again for cutting: a day of thin-sheet work is not run without it.
MOPAHolds thin sheet flat through the moment an outline breaks through, and belongs with any cutting configuration.
MOPAEverything else on this page ships on every machine. The screen, camera, microscope, connectivity, air cooling, power stage and both laser sources are the machine itself, not a configuration level.

Two sheets side by side
Three comparisons are worth making with another machine’s sheet beside this one, and one is not.

A dash means we hold no published figure for that cell. We would rather leave it empty than fill it from memory.
The bench space a machine occupies is the cabinet plus whatever its cooling needs. Then compare function coverage, because it changes what you are counting: the European benchmarks are single-function welders, so marking and cutting on those benches are further machines with further footprints.
Then the exclusions: what the warranty leaves out, how many entries the consumable list really has, and what supply the machine asks for.
We will not claim the M3 beats those machines on every welding parameter. What none of them does is put welding, marking and cutting on one 30 kg air-cooled bench unit, and that is the comparison this sheet is built to win.
Who the M3 suitsA sheet answers what a machine is rated for. Your own metal answers what it does on your work.
