A cylindrical enclosure, or can, is formed with one end closed and the other end open. The can is partially filled with a first layer of a secondary explosive constituting an output charge, and a second layer of a primary explosive constituting a transfer charge. An explosive header is inserted into the can adjacent to the transfer charge, and the open end of the can is crimped inwardly to secure the header. The header is assembled with two concentric electrodes which are gold plated at a header face. A heater wire is positioned across the face, and is bonded to the electrodes by a first probe which presses against the wire and passes sufficient electric current to heat and soften the gold plating about the wire. Excess wire is severed by a second probe which passes sufficient electric current to melt the wire.
