I had a reply all typed out and then my internet connection quit on me....
...anyway refer to Table 4.12 for the essential variables that require a welder to requalify and notice that there is no essential variable for gas. So the welder can qualify with FCAW-Gas shielded and also weld with FCAW-Self shielded without requalifying as long as all of the other variables are adhered to. FCAW-Gas and FCAW-Self are considered the same process.
JJ, Table 4.5 is for the essential variables that would require a WPS to be requalified...so it doesn't apply to the welder only the WPS.
