Abstract
A method of dispensing metered portions of molten lead comprises the steps of providing a heater body with a lead reservoir that produces sufficient heat to form molten lead and providing a lead dispensing shuttle plate with at least two lead metered cavities that are filled with molten lead in a fill position. The heater body is movable between a dispense position and a feed position. At least one of the metered cavities releases the molten lead when the heater body is moved to the dispense position. In one aspect, the method comprises supplying a strip of lead so that when the heater body moves to the feed position, it receives a portion of the strip of lead. In another aspect, the method comprises injecting inert gas over the lead reservoir and into the dispensing metered cavity to prevent air from entering the metered cavity.
