ignitronn.

Brit.

/ɪɡˈnʌɪtrɒn/,

/ˈɪɡnᵻtrɒn/, U.S.

/ˈɪɡnəˌtrɑn/

Etymology: < ignit- (in ignite v.,) ignit- (in ignition n.) + -ron (-tron suffix).

Electronics.

A kind of mercury-arc rectifier capable of handling large currents and having a pool cathode, a single anode, and an igniter to initiate the arc afresh in each cycle (the timing of this being used to control the output).

1933 D. D. Knowles in Electronics VI. 164/1 The Ignitron* is the latest arrival in the rapidly growing family of industrial electronic tubes. It is a tube in which conductivity is established by igniting the arc. [*Note] Pronounced like the word ‘ignite’.

1951 Engineering 14 Sept. 323/3 The ignitrons, which are water-cooled,..act as an electronic contactor which controls the current in the primary of the welding transformer.

1962 Newnes Conc. Encycl. Electr. Engin. 380/2 The larger ratings of ignitron are constructed with a double-walled stainless steel envelope, water being circulated in the jacket so formed for cooling.

1967 H. Cotton Adv. Electr. Technol. xv. 726 Typical applications of the ignitron are (a) small-power spot welding, (b) large-power control of variable-speed d.c. motors, such as certain types of colliery winder.
