What the job demands
Findings work is repetitive: the same joint, many times over. Programmable memory and a comfortable display save more time across a shift than a power upgrade does.
Where more than one machine covers the job, the choice comes down to volume and site constraints rather than capability. The production scenarios page shows how that decision is made for eight real jobs.
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 | QCW-300W | 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 · AC 220±10% 50/60Hz | Socket type, breaker rating, and whether the site runs 50 Hz or 60 Hz. |
| Cooling | Air & water cooling · Built-in cooling · Air 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. |
