D1.1 only recognizes F1 through F4 for SMAW welding electrodes.

Generally, for welding processes other than SMAW it is the electrode specification that is used as the limiter. In your case, ER70S-2 is listed in AWS A5.18. The welder would be qualified for all filler metals used with the welding process (GMAW). For GMAW, it would include all the filler metals classifications listed in A5.18, A5.28, and A5.36 (A5.36 has been withdrawn by AWS) compatible with the process. That would include bare electrode and metal cored electrode, but not FCAW electrode because that is considered a different welding process.
