How to prepare a new glow-wire?

A new glow wire shall be annealed for a total at least 10 h by being subjected to a current of at least 120A before being sued for a test run. The total annealing time may be achieved cumulatively. To avoid damage, the thermocouple shall not be installed during annealing. At the end of annealing, the depth of the thermocouple pocket hole shall be verified.
