Tefal GV9570E0 Pro Express Ultimate high pressure steam iron

Choose a board that is height-adjustable to adjust it to your
height. It should be steady and robust so that you can place
the ironing appliance on it.
The board should be perforated to allow the steam to pass
through the fibres of the fabric to soften it and make
ironing easier. The ironing board cover should also be
suitable to allow the flow of steam through.

To avoid damaging the soleplate, follow this advice:
• Always place your iron on its heel rest or its base
(depending on model).
• Avoid ironing over abrasive items (buttons, zip fastenings,
etc.).
• Never clean your iron's soleplate with abrasive or metallic
pads.

Yes this is because the steam is generated in a separate
area away from the soleplate of the iron. This allows you to
obtain steam on the lowest heat setting, e.g. silks.
However, when the iron temperature control is set to the
lowest setting you must also set the steam output control
dial (depending on the model) to the low position,
otherwise water droplets may appear in the steam.
