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 size of the scraper is calibrated according to the mold's crucible size. In order to select the appropriate scraper, the type of metal powder associated with the mold must be known:
- KG10 sraper type: for use with metal powder cartridges from KW45 to KW115
-KG12 scraper type: for use with metal powder cartridges from KW150 to KW250
- KG13 scraper type: for use with metal powder cartridges from 2XKW150 and above
