Nalla,

The variables for the welder allow a wide range of P-Nos permitted, but the F-No is an additional variable to be considered.

GTAW manual qualifies GTAW manual,
P8 qualifies P1 thru 11 and 41 thru 49,
6G 6mm 2" qualifies all positions 1" and over, deposited weld metal up to 12 mm.
and F 6 qualifies F-No 6 ONLY!

This looks like you should have an experiences AI looking over your papers.
