Grounding

The Furseweld Connection

Molds

Furseweld graphite molds are dedicated to producing one type of connection. With care, they should be capable of producing up to 75 connections each. Mold size and complexity varies, and is denoted by a price key, from oneupwards.Each mold carries a tag which gives the mold part number,the weld powder size for use with the mold and theconductor sizes for which it is intended.

Handle Clamps

The majority of Furseweld connections have at least twicethe 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, highcopper content alloy, it will withstand repeated fault currents,and will not loosen in the way that mechanical connectorscan.Corrosion resistance too, is exceptional, due to the alloy’svery high copper content (in excess of 90%). Handle clamps provide a means of both handling the mold,and also of clamping the mold halves together (or of clamping the mold to the surface to which a connection is to be made).

Standard Tools

Furseweld® Exothermic Grounding - 19554 G

A flint gun is required to start the reaction.Cleaning tools for conductors, surfaces and molds include: Cable Brush-for cleaning cables and other circularconductors such as rods.Mold Scraper-for removing slag from the mold crucible,after firing.Mold Brush-for final mold cleaning.File Card Brush-for cleaning conductors and surfaces.

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 powder’s nominal weight in grams.The weld powder packaging also contains retaining discsand starting powder. The retaining discs are contained in aseparate bag within the box. The starting powder iscompacted into the bottom of the cartridge, underneath theweld powder, and is released by tapping the cartridge base firmly.Furseweld weld powders are suitable for makingconnections from copper to copper and from copper to steel.

Standards Compliance

A representative range of Furseweld connections have beensuccessfully tested in accordance with the requirements of IEEE 837-1989 - Standard for Qualifying Permanent Connections Used in Substation Grounding.Testing in accordance with UL and CSA.
