More Information
Summary:Trigger devices for igniting an exothermic reaction is provided. The trigger devices may be flint type trigger devices and electronic type trigger devices. The flint type trigger device has a housing with a spark opening on a rear wall of the housing. A mold mounting assembly is secured to an exterior of the rear wall of the housing. A motor assembly is secured to the inside of the rear wall of the housing. The motor assembly has a flint wheel attached to a shaft of a motor, where the flint wheel is located adjacent the spark opening. A flint assembly is positioned within the housing such that a flint of the flint assembly is in contact with the flint wheel. A controller positioned within the housing is configured to selectively activate the motor to cause the flint wheel to rotate against the flint to create one or more sparks that are ejected from the spark opening.
