Dear John, LF Group,I have a reel of wire from this company, and it is definitely of the solderable, "self-fluxing" polyurethane enamel variety, as is most enamelled wire you buy nowadays, which is usually a yellow to orange or pink colour, but can be other colours too. The older type of enamel is usually a much darker brown and has to be scraped, burned or chemically removed. There are also various kinds of high temperature enamel for motor winding, etc., but these are less common. Uwe's technique works very well with fine wires, but for thicker wire like 0.7mm you might need quite a big soldering iron, or a solder pot, to get it hot enough to make the enamel melt and bubble off. If you only have a small iron, it is easier to scrape the enamel in the traditional way. I think the "toxic fumes" warning is relevant for people working on a transformer production line all day, but for soldering the occasional wire the quantities are too tiny to cause a problem. I have never found the fumes significantly irritating - but use common sense!
