Earth Rod to Bar Tee Horizontal Tape

14.2 and 17.2 = copper bond / 16 and 20 = solid copper/steel

LEGEND:

Conductor Size:

• A and B denote the sizes of conductors being joined.
• Bar is specified by its dimensions, x and y.
• Circular conductors can be either:
  • Stranded (e.g., cable)
  • Solid (e.g., ground rod, rebar).
• If both stranded and solid conductors are applicable, this will be noted in the relevant table.
• All conductor dimensions are provided in millimeters (mm) unless specified otherwise.

Price Key:

Moulds are priced according to their size and complexity and are categorized into pricing bands, referred to by a price key.

Weld Metal:

Weld metal is specifically sized for each mould. Normally, this is one carton of weld metal but when more than one is needed it will be indicated by a multiplier; such as 2 x #150.

Clamp:

• Each type of mold requires a specific clamp.
• If multiple molds use the same clamp, you only have to order enough clamps for the number of operators you will need for your job.

Sleeve (Rail Applications):

A copper sleeve is used to increase the diameter of smaller conductors to make them weldable.

Hammer Die (Rail Applications):

A hammer die flattens one side of a conductor for better contact with the rail, improving the weld quality.

The AI Weld Process:

Six basics steps in the AIWeld Process lead to a successful exothermic weld:

1. Insert the conductors into the mould cleaned while ensuring that the mould is dry with minimal moisture. This can be ensured either by the process of preheating or possibly a test connection.
2. Fit the provided metal disc at the bottom of the mould crucible.
3. Pour in the weld metal completely, which you find under its green lid.
4. Add on top of the weld metal, the starting powder found under its red cap. Only a small quantity shall be applied on the lip of the mould for easy ignition, then close the lid.
5. Draw a charge from the flint gun to ignite the starting powder, pull the chargeback immediately after firing in order not to foul the gun.

Caution: Have no part of your body over the top or in front of the aperture

1. When 20 seconds have elapsed open the mould by crank handle. Use the cleaning brush to remove slag and clean the mould and crucible and lid liberally.
