The S in ER70S-6 indicates the filler metal is:

Explanation:
The S in ER70S-6 shows the form and metal family of the filler metal: it is a solid steel welding wire. This designation identifies it's a solid wire used for carbon steel and typically employed with shielding gas in MIG welding. It’s not about softness, stainless, or any other descriptor—those terms aren’t what the code uses. So the filler metal is a solid steel wire (not flux-cored or stainless).
