QCW Jewelry Laser Welder: One Connection to the Room It Goes Into
What decides whether a machine can go in is rarely the machine. It is what the building has to do first.
Between this machine and your building there is one connection: a power cable. No water in, no water out, no drain.
What this is
A fiber QCW welder built for thin wall, for parts with something heat-sensitive next to the joint, and for work that has to keep a cadence. Benchtop, air-cooled, built in our own plant.
What it asks of the room
A socket at 110–240 V, 50–60 Hz. Nothing plumbed, nothing drained, nothing that has to be scheduled with anyone else in the building.
What the QCW Laser Welder Asks of Your Supply — One Cable, 110–240 V
Power is a cable on this machine, not a project.
What it takes.
110–240 V at 50–60 Hz, 2 kW maximum input, air-cooled. That is the whole electrical requirement, and it is the reason this one goes on the bench you meant it for rather than the bench nearest the panel.
Why that is the item worth checking first. The electrics are the one part of a machine purchase that is not yours to schedule. An upgrade needs an electrician, a slot in the building's calendar and, often, somebody else's sign-off — none of which move at the speed of the job that made you start looking. A machine that runs on what the wall already gives you takes that whole queue out of the decision.
What it draws while it runs.
Sixty per cent of what it takes from the wall leaves as beam. The rest is what the room has to absorb — and a room with an air-cooled machine in it absorbs less than a room that is also running a pump.
Air-Cooled, With No Water Circuit — and What That Decides
What you save is not one installation. It is who gets to decide where the machine stands.
Nothing plumbed.
No water in, no water out, no drain, no tank to find room beside. The cooling is air, and it travels with the machine.
A tank is a standing job.
Top it up, watch the joints for weeps, keep it clean through summer and keep it from freezing in winter, and leave enough space around it to service it. None of that appears on an order. All of it appears in the week — and when a tank stops, the machine stops with it.
What it actually decides.
A machine with a water circuit stands where the plumbing lets it stand. This one stands where the work is. That is a smaller sentence than it sounds: over a year, the bench a machine ends up on decides how often it gets used, and by whom.
What air cooling asks instead.
Air cooling is not nothing — it takes its cooling from the room, which makes the room part of the machine. Water asks the building for connections; air asks it for conditions. We do not publish a figure for that, because the figure that would matter is the one in your room, not the one in ours.
Both of those are settled by the wall you already have.
The rest of it goes on paper.
Take this one to a quoteWhat This QCW Fiber Laser Welding Machine Will Hold
A parameter range is only useful against one question: will it hold the class of work in front of you.
- Pulse width 0.2–15 ms, continuously adjustable.
- The short end is what keeps the heat from walking into whatever is sitting next to the joint. The long end is for a joint that needs filling rather than tacking. Continuous means you can sit between them instead of choosing a step.
- Repetition rate 1–20 Hz, continuously adjustable.
- One pulse at a time when you are placing a tack under magnification; the top of the range when the joint is a run of overlapping spots rather than a point.
- Beam quality, BPP 1–2 mm·mrad.
- How tightly the beam can be brought to a point — and, more usefully, how predictably it stays that way from one setup to the next.
- Ytterbium fiber at 1080 nm, diode life over 100,000 hours.
- The source is not an item on the maintenance schedule.
- Average power comes in several configurations, and peak rises with the configuration.
- Which configuration your work needs is a question about the joint rather than about the spec sheet, and it gets settled on the quote rather than here.
Where it holds, and where it doesn't.
It holds thin wall, joints made next to a surface that is already finished, and runs that have to come out the same on the fortieth part as on the first.
It is not the machine for section that wants more energy in a single pulse than a welder built around low heat input is meant to put there — that trade is set out below, in full.
Bench Space for a Benchtop Laser Welder — and the Room Around It
Fitting is the first question. The second is how much bench you still have once it is there.
What you need around it.
Setting a machine down is not the same as installing it. In front of it you need room for your hands and for the part to rest while you work on it; behind it you need air. Those two are what decide whether the bench still works afterwards, and neither of them is in the outline.
It stays movable.
This one is in the weight class a person can shift. That matters less on delivery day than a year later, when the bench it belongs on turns out to be a different bench — a machine you can lift is a machine that is allowed to change its mind.

The Average Power Trade-Off — What This Machine Is Not the Strongest At
There is work each of the four should not be bought for. Here is this one's.
The trade itself. What it gives up is average power. Of the four machines we build, more of it sits elsewhere — and everything above is bought with that.
When it costs you.
It costs you on section that wants more energy in a single pulse than a machine built around low heat input is meant to put there — heavier wall, deeper fill, a joint you would rather hit hard once than build up in passes.
If that is most of what crosses your bench, this is the wrong one of the four, and we would rather you read that here than find it out on the bench. Which of the four it should be instead is a question we answer on one page, with all four side by side.
When it doesn't.
It does not cost you on thin wall, on parts with something heat-sensitive sitting next to the joint, or on runs that have to keep a cadence and come out the same every time. That is the work this machine was built around, and it is why the electrical side and the cooling side look the way they do.
Whether the process suits your part at all is the question that comes before this one, and it is settled on the part rather than on the machine — we set out how we settle it.
Two Ways to Take the QCW Jewelry Laser Welder Further
One puts it on paper. The other puts a person on your joint.
If this is the one, the next thing that has to exist is a document with this machine and a quantity on it, written against where it is going and the supply it will land on.
