Abstract

A circuit and wire lead welder has two insulating boards 1 and 2 arranged so that a metallic foil 4 can be fed between them. Each board has corresponding holes 3 located in a grid pattern. A unit 10 contains a plurality of carbon electrodes 6 which may be inserted into the holes 3. The carbon electrodes 6 are connected to a power supply 9 through a cold lead 11. The power supply 9 is connected by hot lead 12 to a brush 8 to make contact with the foil 4. The objects to be welded, for instance two wires 7, are placed in the hole 3 of the lower insulating board. A solid area of foil 4 is fed over the holes and the carbon electrodes 6 are inserted in the holes 3 until contact is made with the metallic foil 4.

Circuit and Wire Lead Welder

A circuit and wire lead welder has two insulating boards 1 and 2 arranged so that a metallic foil 4 can be fed between them. Each board has corresponding holes 3 located in a grid pattern. A unit 10 contains a plurality of carbon electrodes 6 which may be inserted into the holes 3. The carbon electrodes 6 are connected to a power supply 9 through a cold lead 11. The power supply 9 is connected by hot lead 12 to a brush 8 to make contact with the foil 4. The objects to be welded, for instance two wires 7, are placed in the hole 3 of the lower insulating board. A solid area of foil 4 is fed over the holes and the carbon electrodes 6 are inserted in the holes 3 until contact is made with the metallic foil
4.

The contact made with the metallic foil completes the electrical circuit from the power supply, heat is dissipated and the portion of the foil below the electrodes 6 is melted. The molten metal from the foil falls onto the objects 7 to be welded in the hole in the lower insulating board 2 and upon solidification effects a weld 3. Then the spent foil 5 is removed from the insulating boards and new foil 4 is inserted. A number of objects may be welded simultaneously, the number varying directly with the number of holes in the insulating board and the number of electrodes. The foil may be used as one electrode of the welding circuit for timing the welding operation, the length of the operation depending upon the properties of the foil....
