LF,

I have a reel of such wire labelled as follows:

"Wire copper enamelled
Part 1230983 0.71 mm 1/2 kg
Solder only in well ventilated area. Fumes are toxic"

The manufacturer is stated to be Rowan Cable Products Ltd.  I found their 
website but don't seem able to get into it to find out whether the covering of 
the wire is solderable and (if so)  whether any special techniques are required.

Can anyone advise, please?
