Assembly of a carbon arc lamp
Take a single-sided razor blade and pinch it off on a corner of the razor blade with a haemostat (or vice grip) so that the cutting edge extends below the jaws at a depth slightly less than the thickness of the insulation jacket. At a point about one foot from the socket end of the cord, slit the jacket for a length of about three feet and separate the wires from the jacket by cutting off the slit insulation material. At
the mid-point of the white wire (or blue if European colour-coding is used), cut and strip the ends by half an inch to one inch and attach (preferably solder) the wires to each alligator clip.
