This machine consists ofthe mechanism unit capable of brazing bridges of the rims of spectacles in the various designs and the povver supply unit capable of setting the current suited to brazing conditions for right and left. This machine assures the high quality and stable brazing work vvith such features that the distance, the angle and the storoke ofthe left and the right electrodes can optionally be set up, and thatfor preventing the overheating and the rapid cooling, the current intensity can be redused gradually so that the work is protected from being overheated and the brazing temperature is maintained at a proper level.
Further, the interlocking mechanism is incorporated in this machine to protect the jig, etc. from being damagedly the erroneous operations in the automatic mode as weII in the manual mode.
