I know different metals can be a pain in the arse to weld and that mild steel sheet is the easiest to use but can my welder doo it or not is the question?

(feck knows if I can though. LOL)

you'll have to clean the galv off the area to be welded and then re-address corrosion in that area.

or if you dont want the welds to be visable, use stainless wire.

you shouldnt really weld galv sheets as cyanide deposits are left behind. you can weld them as long as you grind off the area to be welded and at least 3-4 cm of surrounding area. as for stainless, you can use a mig with mild steel wire although you can buy a small reel of stainless wire from places like machine mart etc.

never weld galvenised steel the chemicals that are given off when welding are poisoness. with a mig you can weld ally and stainless as Ash says. you just need to make sure you have the correct gas and wire for the job
