Abstract: A metal rod is inserted through the left and right capillary tubes of a gas discharge device. One end of a coaxial bulb joining one capillary tube is heated until the glass thereof is softened. Then, the metal rod is rotated within the two capillary tubes until the bores thereof are axially aligned. Then, the softened end of the bulb is allowed to cool to fix the aligned capillary tubes. Then, the metal rod is removed from the discharge device.
