Abstract :
Accurate control of high currents for resistance welding may be obtained by igniter-type mercury-cathode tubes capable of conducting 7,000 amperes in impulses of from less than 0.01 second to several seconds duration. This paper describes design principles and manufacturing technique for tubes of the sealed-off type.
