He pretty much nailed it on the head there; that build is called the Lobster, an anti-AC build that focuses on the sheer destructive power of the Cetus weapon arm. Your best bet would be to use this build:
CR-H81S4
CR-C83UA or CR-C89E
WA02-CETUS
LH07-DINGO2
CR-B83TP
CR-F82D2
CR-G91
ANANDA
CR-WB85RPX or WB07RO-ORTHOS
CR-WB69RA
There's no need to purge any parts, although it would be helpful to do so as the rocket is fairly heavy. Back boost away and blast her with the CETUS on mode 2, she won't even try to dodge them and will probably last around 15 seconds.
If you are trying for the hard way, kill her with dual HP pistols with 69Hs as backup.
