Abstract
An electrical heating element, such as a graphite block, is resiliently held in electrical contact with a support block by a plurality of spring loaded connectors. The support block is electrically connected to an electrode. The spring loaded connectors extend through a plate, the heating element, and the support block. The connectors extend through slot shaped openings in the heating element such that the heating element can move in the direction of its length relative to the plate and the support block to provide a first degree of freedom between the electrode and the heating element. There may be up to six degrees of freedom in the mechanical connection between the electrode and the heating element.
