Oh, i see now

The bad is that these electrical devices want 110 Voltage which here in Europe we don't have in our homes. Of course for my good luck, i'm somehow an electrician boy and i can transform the 240 into 110, no problem. Ok, but i saw somewhere that we are using towels on the spots we want to cover, and then with the heat gun and the iron, we "do what we have to do" above of the towel. Is that right?
