Ladies and Gentlemen,
Worked with A7 as NYCDOT employee until out on my head for excess honesty ! My guess is 7018 SMAW with 250 preheat and welder doing in out of puddle technique. Said steel is over 100 years old without concern about preheat. The light loading mentioned and chemistry is concerns.
