ASME Section-IX considers GMAW and FCAW are similar process. The transition current and voltage for short circuit, globular and spray transfer are quite different. The values can be obtained from various sources including books, journals, papers etc.
For example:- "GMAW-S
(S. Circuit transfer or Dip transfer)" S. Circuit or Dip transfer "CV
Very low voltage process" DCRP (DCEP) 17 V -22 V
