CADWELD EXOTHERMIC CONNECTION (Earth copper wire welding)
CADWELD EXOTHERMIC CONNECTION
A WELDING PROCESS THAT ELIMINATES THE
CONNECTION BY FORMING A MOLECULAR BOND.
Connections are the weak point of all electrical circuits and
especially earthing circuits subjected to aging and corrosion.
The capacity of an earthing circuit to protect the safety of
personnel depends on the quality of the connections made.
BS 6651 (1992) STATES :
“Any joint other than welded represents a discontinuity in the
current conducting system and is susceptible to variation and
failure.”
CADWELD – THE MOLECULAR BOND
The Cadweld process provides a way to produce copper/
copper, copper/galvanized or plain steel, copper/copper
clad steel, copper/bronze/brass/stainless steel, steel/steel,
molecular bonds with no external energy or heat source.
The principle consists of bringing together a welding
materials and ignition agent in a suitable graphite mould.
The reduction of copper oxide by aluminium produces
molten copper and aluminium oxide slag at extremely high
temperatures.
The shape of the mould, its dimensions, and the size of the
welding material, are all dependent on the items to be welded
INSTALLATION IS EASY!


4 SIMPLE STEPS FOR PERMANENTLY WELDED
ELECTRICAL CONNECTIONS
The Cadweld Plus Control Unit initiates the reaction of
the metal crucible. The standard unit includes a 1.8 meter
(6-foot) high temperature control unit lead. The lead attaches
to the ignition strip using a custom made, purpose-designed
termination clip.
After the termination clip is installed on the ignition strip,
the installer pushes and holds the ignition button to start a
charging and discharging sequence. Within a few seconds the
control unit sends a predetermined voltage to the ignition strip
and the reaction is initiated.

1.Insert Cadweld Plus package into mould.
2.Attach control unit termination clip to
ignition strip
3.Press and hold operating switch and wait for the ignition
4.Open the mould and remove the expended
steel cup – no special
disposal required
