The exothermic welding is a self-sufficient process to achieve high quality electrical connections between copper, copper alloys or steel conductors. The process implies the use of a graphite mold allowing the molten metal present inside to come in contact with the conductors present and to weld them in a definitive way.
The pre-assembly of the different parts of a mold as well as the holding of the conductors or elements to be welded present in the mold, is carried out using a handle clamp adapted to each mold size:
- HCB00 type handle clamps: are used with mini molds (size B - type -B references)
- HCC00 type handle clamps: are used with standard moulds (size C - type references -C-)
- HCD00 type handle clamps: are used with maxi molds (size V or D - type references -V- or -D-)
