Abstract: arc drop and 12R loss can be approximated by using a 100 volt loss in the tube. The anode , needed to prevent voltage breakdown. IGNITOR VOLTAGE The ignitor is a standard welder ignitor which at 200 volts applied will take up to 100 usec to fire with a 30 ampere short circuit pulse. DC short circuiting service requires 1500-3000 volts with 100-200 amperes short circuit current and less , ignitor circuit. Approximately one microsecond is added to the delay for every degree C that National Electronics
