It may be of fundamental importance to note that whereas British fuse manufactures can obtain supplies of fine wire of 0.0004" diameter, and finer, and can handle such wires, the Germans appaer to have difficulty in drawing, with any accuracy, wire finer than 0.01 m.m. for this application, but, more important, all those who were interrogated stated that with the cheap labour employed they would be quite unable to handle finer wires, even if such were ready available. Nevertheless, by the development of the temperature controlled solder technique they are able to produce surge-resisting fuses of as low a rating as 10 m.A. carrying. But should, however, be realised that British single filament fine-wire fuse-manufacturing technique generally sets a practical low-limit current of 30 m.A.-carrying (say, 60 mA. blowing-rating). In the higher ratings of this range, say up to 1 Amp. the British production is comparable, and it is cheaper to manufacture in Britain in the way that fuses are being made now. The German method tends to be advantageous for ratings of 1 Amp. and over, but it should be recorded that a comprehensive batch of Wickmann fuses tested at R.A.E. did not appear to be very consistent. ......
