Abstract: The present invention is directed to an adjustable electrode for oil burners. This electrode includes an elongated main electrode, an electrode tip support member and an electrode tip. The elongated main electrode has a conductive core element and has an outer end and an inner end. The inner end is adapted for connection to an electrical path of a source of electrical power, and the outer end has an electrode tip support member conductively connected to it. The support member has a central axis and has an electrode tip-receiving orifice therethrough at a predetermined angle relative to the central axis. Additionally, the support member has a locking mechanism for locking the elongated electrode tip in the orifice and for unlocking the elongated electrode tip for adjustment in and removal from the orifice. The locking mechanism may be a set screw, spring, swing lever or other locking mechanism.
