    Some can, but I know that some carbon steel TIG rods aren't recommended for O/A welding.

      You shouldn t use O/A mild steel filler rod for TIG, because it is lower quality then the TIG filler rod. To produce a high quality weld with TIG on mild steel you want a filler metal with the highest number of deoxidizer possible, because of this I generally use ER70S-2. If the ER 70S-2 isn t in stock I go with ER70S-6.
