SOLDERING LITZ WIRE

REQUIRES MUCH SKILL. Litz wire, frequently employed fot making indoor loop aerials, is very, difheult to handle, ani soldering it, in the hands of the average «mateur, becomes an impossible task, unless considerable pafience and a fair amount of skill is applied. This is the way this; or any other standard wire, should be dealt with. Vor a half an inch or so from its cnd it should he carefully unravelled and each strand cleaned separately. Gently scrape with a sharp ':nife eacli tiny wire until it is clean. Do not use force or endeavour to hasten the operation, for if you do the wire will break. If the wires are enamelled the operation may be a long one, but if the joh is to be satisfactory it will. have to be carried through. Care Needed. ext cover each strand very cares fully with flux. Having doue this, gently twist the whole lot together again, taking care not to rub the flux off with the fingers. ‘Twist them up very earetuily, but tightly, together a pair of pliers, the jaws of which have previously been cleaned. Next get the bit of flic soldering iron well cleancd and tinned. On one tace of the soldering-iron bit get a large bead of imoften solder, and in this place the end of the Litz wire. Hold it there for two or three moments and thes withdraw it, and you will find that it is successfully welded together by meaus of a inass of permeating solder. You can now proceed to join it to a soldering tag or other such point. iu the usual way, confident that a strong connection will result,
