Читать книгу Woodburning with Style - Simon Easton - Страница 28

Whichever machine you choose, remember to ensure the tips are completely cool before changing them by hand. The glowing red heat of a hot wire nib is a very clear indication it is too hot to handle, but this disappears within seconds of the machine being switched off. The nib will still be too hot to touch for some time, so leave the kit alone for at least 10 minutes or so before attempting any alterations. If in doubt, press the nib on a piece of scrap paper: if the paper does not burn or become discolored in any way, you may be able to handle the nib. Caution is the best advice I can give; otherwise, your hands and fingers may soon be covered with small nib-shaped scars.

It is often very hard to tell if a pyrography nib is still hot, so please be cautious. Treat all nibs as if they are hot unless you have verified they are definitely not. Test a nib on a piece of scrap wood or paper first before touching it.
