Abstract
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.
Claims8
An ignition source system for an exothermic reaction mold device, which system comprises:
- a crucible in a block with an open top so that said crucible receives an exothermic weld material;
- a removable lid covering said open top;
- an electronic thermal igniter assembly having an ignition body, said ignition body extending into said crucible so that said exothermic weld material may be ignited by said electronic thermal igniter assembly;
- and
- an igniter plug having a connector housing unit with a spring contact mechanism for capturing said ignition body wherein said ignition body is retained in a recess of said igniter plug.
An alternative ignition source system for an exothermic reaction mold device, which comprises:
- a crucible in a block with an open top so that said crucible receives exothermic weld material;
- a lid covering said open top wherein said lid has an opening therethrough;
- means to ignite said exothermic weld material within said crucible with an electronic thermal igniter assembly having an ignition body which extends into said crucible wherein said electronic thermal igniter assembly includes an igniter plug, at least one battery and at least one switch;
- and
- means to alternatively ignite said weld material within said crucible with a mechanically generated spark.
