Superweld 1×7 wire is an amazing product that allows anglers to rig leaders quickly & easily using the flame of a cigarette lighter. To rig, the tag end of the wire should be twisted back upon itself, at which point the connection should then be passed back and forth over a light flame. The black nylon coating will then soften and fuse together to form a permanent, high strength bond. Care should be taken not to melt the black coating completely off, as this will weaken the join. A very popular wire for anglers chasing Barra, small Mackerel and Tailor.
