I pie cut the ducts on a Detroit Diesel air cooler to spread them apart an inch and a half. Used a Lincoln Tig 300 with watercooler and 4043 to welded it up. I think 5356 would have been a better choice but the boss wanted it done with what he had....so the unfortunate part I was stuck trying to use 4043 and a balled Thoriated Tungsten.....it didn't come out too pretty. I know thoriated isn't the right tungsten for the job and I can see why now. Dave
