A vacuum interrupter uses a high vacuum to extinguish the arc between a pair of contacts. As the contacts move apart, current flows through a smaller area. There is a sharp increase in resistance between the contacts, and the temperature at the contact surface increases rapidly until the occurrence of electrode-metal evaporation.
Typical vacuum levels for brazing range from pressures of 1.3 to 0.13 pascals (10 −2 to 10 −3 Torr) to 0.00013 Pa (10 −6 Torr) or lower. [11] Vacuum furnaces are most commonly batch-type, and they are suited to medium and high production volumes.
Torr-Seal, or its generic equivalent Hysol-1C (US brand name) or Loctite 9492 (EU brand name), is an epoxy with resin and hardener for use in vacuum environments. It will begin to degrade at high temperatures but otherwise is very stable with very little outgassing. Other vacuum-rated epoxies are also available.
