Ignition source system for an exothermic reaction mold device
View Patent ↗An ignition source system for an exothermic reaction mold device for welding conductors. The system includes a crucible in a block with an open top so that the crucible receives an exothermic weld material. The conductors to be welded exothermically are placed in the weld cavity of the mold. A lid covers the open top wherein the lid has an opening therethrough. An electronic thermal igniter assembly has an ignition component receivable through the opening in the lid so that the exothermic weld material may be ignited by the electronic thermal igniter assembly. The igniter plug rests on top of the lid and the ignition body is retained in a recess within the igniter plug.
