The JW80 and the Mini 10 JW100EP sit next to each other in the same family, which is exactly why the choice is not obvious. Here is the specification difference, stated plainly, and the jobs that push the decision either way.
Specification, side by side
Published figures, not marketing categories. Every model links through to its own specification page.
| Model | Power | Source | Cooling | Weight |
|---|---|---|---|---|
| JW80 | 80 W | YAG | Air & water cooling | 29 kg |
| Mini 10 JW100EP | 100 W | YAG | Air & water cooling | — |
The difference that matters
Only the fields where these two machines actually differ are shown. Everything omitted is identical on both.
| Parameter | JW80 | Mini 10 JW100EP |
|---|---|---|
| Laser power | 80 | 100 |
| Display | 7-inch HD touch-screen | 10.8-inch touch-screen |
| Weight | 29 | — |
| Options | Heraeus xenon lamp, Motic microscope, integrated camera | Intelligent voice alarm, integrated camera, programmable memory |
The headline gap is power: 80 W against 100 W. In practice that is a difference in depth per pass and in the section thickness you can fuse in a single shot — not a difference in accuracy or in mark quality. If your work sits comfortably inside what the JW80 already does, the extra power buys cycle time you may not need.
Where the decision is genuinely marginal, the deciding factor is usually the site rather than the specification: supply voltage, whether a chiller position exists, and how much bench or floor space is actually free. Send both models on the quotation request and we will confirm against your layout.
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 | JW80 | 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 10 JW100EP | 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 | No separate chiller position is required for these models. |
| Weight and access | 29 – 29 kg | Floor loading, door clearance, and whether a pallet truck can reach the final position. |
