THE FURSEWELD CONNECTION The majority of Furseweld connections have at least twice the cross sectional area of the conductors being joined, and an equivalent or greater current carrying capacity. Because the connection is a fusion of high conductivity, high copper content alloy, it will withstand repeated fault currents, and will not loosen in the way that mechanical connectors can. Corrosion resistance too, is exceptional, due to the alloys very high copper content (in excess of 90%). FURSEWELD EQUIPMENT AND ACCESSORIES WELD POWDERS Furseweld weld powders are contained in plastic cartridges, and are packed in plastic boxes of 10 or 20, depending on their size. Different joints require different powder sizes, and the size relates to the powders nominal weight in grams. The weld powder packaging also contains the retaining discs and the starting powder. The retaining discs are located underneath the cartridge caps, on top of the powder, or are contained in a separate bag within the box. The starting powder is compacted into the bottom of the cartridge, underneath the weld powder, and is released by tapping the cartridge base firmly. Furseweld weld powders are suitable, for making connections from copper to copper and from copper to steel. MOULDS Furseweld graphite moulds are dedicated to producing one type of connection.

EXOTHERMIC WELDING SYSTEMS With care, they should be capable of producing up to 75 connections each. Mould size and complexity varies, and is denoted by a price key, from 1 upwards. Each mould carries a tag which gives the mould part number, the weld powder size for use with the mould and the conductor sizes for which it is intended. MINI MOULDS Price key 3 moulds are mini moulds. They can produce the same joints as price key 4 moulds, but are smaller overall, and therefore lower priced. They are available for many joints using powder sizes up to 115. Mini moulds are not as robust as the larger price key 4 moulds, and require more care to achieve similar service lives, but they do offer a cost effective alternative to price key 4 moulds, particularly where lower numbers of connections are required. HANDLE CLAMPS Handle clamps provide a means of both handling the mould, and also of clamping the mould halves together (or of clamping the mould to the surface to which a connection is to be made). STANDARD TOOLS A flint gun is required to start the reaction. Cleaning tools for conductors, surfaces and

moulds include: Cable Brush - for cleaning cables and other circular conductors such as rods. Mould Scraper - for removing slag from the mould crucible, after firing. Mould Brush - for final mould cleaning. File Card Brush - for cleaning conductors and surfaces.
