What comes across the counter

The Repair Jobs That Arrive at a Bench Most Weeks

Scan for the work you actually take in. Then read the two operations further down, because those are the ones that decide whether a repair bench is quicker with a laser or only busier.

Repair job	How it usually arrives	The joint the laser has to reach
Ring resizing	Shank cut, sized, waiting to be closed	A seam right around a band held in the fingers
Broken chain repair	One failed link, often mid‑length	A joint thinner than the wire beside it
Prong repair and rebuilding	Worn or lost tips on a mounted stone	Metal at the top of a claw, close to the setting
Crack and porosity work	Casting faults, or an old repair reopening	A line or pit to be filled, not bridged over
Small component joining	Findings, bezels, jump rings, clasps	Two parts that must stay aligned while joined
Remodel and custom assembly	Parts of different pieces brought together	Joints planned by the maker, not by the damage
Prototype adjustment	A one‑off altered part‑way through a build	Joints that will be re‑cut and re‑made again

Not every one of these belongs on a laser every time. The two below explain how that call is made.

The operation taken apart

Prong Repair Is Decided by Where the Heat Goes Next

Of everything listed above, retipping is the job most often handed back with an apology. It is worth one section on its own instead of one line in a list.

The tip, the seat and the stone are millimetres apart.

One · Why this one

Everything Difficult About Repair Is Concentrated in a Claw Tip

The tip is small, the stone is right there, and the metal you need to add sits at the top of a claw that carries heat straight down towards the seat. There is no room to work away from what you are trying to protect. If a laser is going to earn its bench space, this is the job it has to change.

The honest framing: you are not adding metal to a prong, you are choosing where heat is allowed to travel.

Two · What it costs when it goes wrong

A Failed Retip Rarely Stays a Retip

Loosened seat. The claw survives, the setting around it moves, and the stone needs resetting.
Under‑built tip. It looks closed at the bench and opens again in wear.
Second polish. Every recovery pass adds finishing work nobody quoted for.
Disturbed neighbour. An old solder seam close by can react before the fresh metal does.
Returned job. A retip that fails becomes a reset, and the reset becomes a credit note.

Three · How it is handled on the M3

Rebuild the Claw in Layers You Can Stop Between

The piece stays in your fingers under the microscope, so the tip is approached from the angle that puts the seat behind the joint rather than beneath it. Metal is added in short placed shots instead of one long pass, and you look at the claw between them. There is no universal parameter set for this: the starting point shifts with the alloy, the wall left on the worn claw and how close the seat sits.

What that changes: heat is committed in amounts you can still stop, not in one shot you cannot take back.

Four · How to judge it

Five Checks You Can Run on Your Own Worn Claws

No published number settles a retip, and we will not invent one. Use a scrap mount from your own repair drawer and answer these instead.

Direction check. Can you reach the tip with the seat behind the joint?
Stop check. Can you pause after one shot and inspect before committing more?
Neighbour check. Does a nearby old seam stay unchanged through the rebuild?
Finish check. Does the new tip need more polishing than the rest of the claw?
Repeat check. Does the second claw on that mount behave like the first?

Five · When to stop

Prong Jobs to Refuse, and What to Do Halfway Through One

Some retips should be quoted as a reset before they start, and some should be stopped in the middle. Neither is a fault of the machine, and both are cheaper than a returned piece.

Almost no wall left. Rebuilding a claw from nothing is a reset job, not a retip.
An old repair underneath. Previous solder can move first — open it up before adding metal.
A piece you cannot hold still. Fix the holding before you touch anything else.
Doubt partway through. Stop, let it cool, look. A paused job is recoverable; a chased one usually is not.

Stone‑set pieces are a separate decision, and we do not claim that all gemstones and metals can be processed safely under the same conditions: gemstone type, any treatment, the setting structure, the distance from the working area and heat sensitivity are all assessed before the piece is touched. That assessment is set out on the gold, silver and platinum page, and an unidentified stone stays an open question until it is identified.

Where the work stays

Every Repair Ends Where the Piece Was Held

The job is taken in, worked and finished in one position. Nothing is unclamped and carried to a second station between two steps of the same repair.

How a repair day is organised around it

The second hard one

Chain Repair Is Won by Holding, Not by Parameters

A broken chain is the repair customers inspect most closely, and the one where the setting on the screen matters least.

Why it is hard

The Break Is Smaller Than the Wire Either Side of It

A failed link is usually thinner in section than its neighbours, and the two ends do not want to stay together. You are asked to join a face you can barely see while the piece tries to hang away from itself. That is a fixturing problem first, and only then a welding one.

The honest framing: if the two faces are not touching, no setting on any machine will join them.

The holding is the repair. The joint is what follows it.

What it costs when it goes wrong

A Bad Chain Repair Is Found by the Customer, Not by You

Ends drifted apart. The joint closes on air and the chain parts again in the hand.
Link fused to its neighbour. Invisible until the chain refuses to drape.
Broken pattern. A rebuilt link that sits differently is noticed before the join is.
Second attempt. Reopening a closed link costs more metal than holding it properly first.

How it is handled, and how to judge it

Bring the Faces Together First, Then Decide Anything Else

Tweezers, a third hand, a pin through the neighbouring links — whatever suits the pattern — before power is considered. The joint is then made under the microscope where you can see the two faces in contact rather than assume it.

Contact check. Under magnification, do the faces touch before anything is switched on?
Drape check. Afterwards, does the chain hang and move like the rest of it?
Pivot check. Did the links either side stay free to turn?
Find‑it check. From the front, can you still locate your own repair?

When to stop: hollow, plated or previously repaired chain is a separate quote — some patterns are cheaper replaced by the link than rebuilt, and it is better to say so at the counter than after the attempt. If a repair fails the drape check, reopen it and hold it again rather than adding more metal on top.

Beyond the two above

The Same Station Also Takes Remodels and Prototype Adjustment

Short notes, not another argument — three kinds of work that sit alongside daily repairs on the same bench.

Cracks and Porosity

A casting fault or a reopened old repair is filled rather than bridged, working along the line in stages so you can see what has closed before continuing.

Findings and Small Assembly

Bezels, jump rings, clasps and catches are tacked in position first and finished after alignment is confirmed, which keeps a crooked part from being joined permanently.

Remodels and Prototypes

A one‑off can be joined, looked at, cut back and joined again in the same session, so a design decision does not wait on an outside service between two steps.

Where this page stops

Work That Still Belongs Somewhere Else

The M3 does not replace every specialised machine for every application, and repetitive all‑day production runs are not what a shared bench station is for. Anything outside the configurations the M3 is validated for should be reviewed before it is promised to a customer.

Asked at the counter

Repair Questions Jewelers Ask Before Trusting a Laser

Start with the work where holding and access decide the outcome rather than heat volume: findings, jump rings, clasps and small assembly. They build the aiming habit on pieces that are inexpensive to redo. Move to chain and prong work once you can place a shot where you intended it, and keep a scrap drawer of failed customer pieces to practise on before a paying job.

Often, but treat the old seam as an unknown rather than as base metal. Solder in an earlier repair can behave differently from the surrounding piece and may move before your new metal does. Inspect the joint under magnification first, and where the old repair is failing anyway it is usually cleaner to open it out and rebuild than to weld on top of it.

Yes. Anyone promising a repair that walks off the bench finished is selling something. What changes is usually how much finishing sits between the joint and the final surface, and how far the affected area spreads from where you worked. Judge that on your own pieces: compare the polishing time on a laser repair against the same job done your current way.

Jobs that need heat through a whole body of metal rather than placed at one point — and anything where a full seam over a large section is the right answer. The two tools sit together on most benches rather than replacing each other. If you are unsure which side a particular repair falls on, describe it to us and we will say so plainly.

There is a real learning curve, and it is worth planning for. Aiming under the microscope, choosing a starting point and reading a joint are built by repetition, and results differ between operators. Practise on scrap in the metals you actually repair, keep notes of what worked on which job, and expect steady improvement. Training and support exists for this stage.

For repair and small‑batch bench work that is exactly the case it is built for. Continuous production runs are a different question and belong on dedicated equipment. The useful test is your own intake: look at a normal week of job envelopes and count how many of them are the operations in the table above. How a repair shop runs it goes through that in detail.
