Why it is listed here at all

Because the alternative is pretending that a €103 bench extractor is the whole of the subject. For a business, this is the class of equipment that meets the obligation — and knowing that helps a reader place the cheaper options honestly.

Stainless changes the calculation

Chromium and nickel in stainless fume are more hazardous than the iron oxides of mild steel. If stainless is your regular material, extraction stops being a comfort and becomes the controlling item in the workshop.

The questions welders ask

Who actually needs this?

Anyone welding as work rather than as a hobby, particularly on stainless — where chromium and nickel compounds make the fume considerably more hazardous. In a professional setting, extraction is not an optional purchase but a duty, and equipment of this grade is what an inspector expects to see.

Is a 3 m (10 ft) arm the point?

Largely, yes. Reach determines how often the unit has to be moved, and a unit that is inconvenient to move gets used at the wrong distance. Three meters covers a bay, so the arm moves and the unit does not.
