The wire used for these toroids is I believe in the category of
"self fluxing" meaning it is designed to dissolve in the presence of
the "high" temperature of molten solder. It is microscopically thin
and the quantity that we work on per hour is very small compared to
an industrial set up where all the right fume extraction is installed.
Scraping is what we used to do before this was available and I
believe weakens the wire leading to unreliability.
