ABSTRACT:
Device for the manual start-up of a plasmotron. The device has a spring biased plunger which constitutes an electrode which selectively bridges the anode and cathode of the plasmotron and creates an arc between the anode and cathode when it is released so as to be retracted by the spring. The device is provided with an automatic lock which secures the plunger in its outer, retracted position and must be released manually to prevent unintended operation of the start-up device.
