as above be carful not to set anything alight,and an extinguisher is a must!

The hardest thing is gettin ur welder setup properly,it needs to be set high enough to penetrate properely but not so high it just blow a hole in the thin steel! This is were practice comes in handy!

I only tried welding for the first time maself a few months ago and u soon pick it up!Just gotta be patient!
