Abstract
A multiple ignition source exothermic reaction mold device. The mold device includes a crucible in a block with an open top for receiving exothermic reaction powder. A lid covering the open top has an opening therethrough. A receptacle in the lid is in communication with the opening so that the receptacle receives starting powder. The starting powder and, in turn, the exothermic weld material is ignited by alternate sources, either by a spark from an ignitor device or by an electric supply sent through an ignitor element.
