A flashed getter, made of reactive material, is heated with induction and the activated material oxidizes, condenses on the cool vessel walls in a thin coating, which continues to absorb gas and oxygen and other impurities, which increases the vacuum vessel's life. Induction generates an electromagnetic field in a work coil that induces currents in the conductive material of a workpiece placed within or near the coil. Friction from these currents elevates the temperature of the workpieces and filler to be brazed.

Getter Firing Lighting Tubes The process was completed within just 10 seconds, delivering the same result time after time, making it ideal for their high-volume manufacturing process Getter firing in corners of rectangular vacuum display By flashing or firing the getter, the residual gases are removed from the inside of the display. Getter Firing Light Bulbs The 2.5 second firing cycle allows for the coil to be move around the part and away within the indexing time of the turnstile table. ## From our blog ## Our Systems for getter-firing with Induction EASYHEAT Models Add your content here.
