Abstract: A method of attaching an end termination assembly to a cold lead of a mineral insulated heating cable. the method comprises removing a portion of a metallic sheath of the cold lead from a proximal end of the cold lead, thereby exposing a conductor of the cold lead. In addition sliding a tubular bushing over the proximal end of the cold lead, and sliding a tubular pot over the proximal end of the cold lead, the conductor thereby projecting from a proximal end of the tubular pot. The method further including aligning a proximal end of the sheath of the cold lead with a proximal end of the tubular bushing, and welding the proximal end of the tubular bushing to the sheath at the proximal end of the sheath. In addition, positioning a distal end of the pot over the proximal end of the bushing, and welding the distal end of the pot to the bushing.
