filler material

[oner355]

Hello everyone,
ok i know this might be top secret information in some fab shops but here goes. Would anyone who works at a fab shop tell me what kind of filler rod you use for heli-arcing 4130 cromoly.
thanks in advance for any help, it is greatly appreciated.

as fabricator said e70-s2 is what most guys in most fab shops use for chromoly cage work. If it is for a part that is intended to be heat treated after welding a different rod is often used.
