      I have a couple of rolls of flux core SS , one is 309 the other is   
   missing part of the label so I don't know but I think it too is 309 . My   
   experience was that the bead starts out cold and tall , but get a half   
   inch down the bead and it goes too hot . I was welding exhaust pipe so   
   that's probably not a fair test . That was also using my old 110V MIG   
   machine IIRC .   
      I've also got some 309L/.023 solid wire but I don't have the proper   
   shield gas for it . Neither straight CO2 nor argon worked well .
