|Abstract: NATIONAL SSRI-51 Solid-State Replacement Ignitron The SSRI-51 is a water-cooled silicon controlled rectifier welding switch which is designed to replace 2 "B" size ignitrons in AC resistance welding controls. It is supplied with an over-temperature thermostat, a firing circuit attenuator to trigger the SCRs, and a voltage spike noise suppressor. The unit is designed complete with mounting buss bar and cable to provide a direct ignitron plug in replacement for 2 "B"- size ignitrons. Maximum ...
