Gold behaves differently under this process than the other jewelry metals, and that changes which settings — sometimes which machine — you need. 10 laser welding machines in the range are suitable for gold work.

Working gold with this process
Gold alloys are reflective and conduct heat quickly, so energy has to arrive in short controlled bursts rather than as sustained heat. Alloy matters more than colour: the copper and silver content of a 14k or 18k alloy changes how it takes a mark and how it flows in a weld pool. Always test on scrap of the same alloy before committing a batch, then save the parameter set.
Parameter sets are not transferable between metals. Build one profile per alloy and per section thickness, name it clearly and store it in machine memory — the models above that offer programmable memory carry that option in their specification.
Choosing between them
A short decision table. Find the row that describes your work, then read across.
| If this describes your production… | Look at | Because |
|---|---|---|
| Occasional work, mixed jobs, tight bench space | Mini 10 JW60EP | Lowest power and smallest demand on the supply in this group — enough for the work without paying for headroom. |
| Regular batches, depth or section thickness at the limit | Mini 7 JW200E | The most capable unit here: fewer passes per piece and more reserve for heavier joints. |
| Limited floor loading or awkward access to the room | JW80 | Lightest unit on this page at 29 kg — easiest to move in and position. |
None of these rows is a rule. They are the questions we would ask on a call, written down — and if two rows point at different machines, that is exactly the point where a conversation saves money.
Site requirements before you order
The three checks that cause most delays, with values taken from the machines on this page.
| Check | On these models | What to confirm |
|---|---|---|
| Electrical supply | AC 220±5% 50Hz / AC 110±5% 60Hz | Socket type, breaker rating, and whether the site runs 50 Hz or 60 Hz. |
| Cooling | Air & water cooling · Water chiller | A chiller position, water supply and drain must be planned into the layout. |
| Weight and access | 29 – 29 kg | Floor loading, door clearance, and whether a pallet truck can reach the final position. |
