Hi Will, this website can probably answer your questions better than me again it is the UK government official site. It seems that the biggest risk is welding stainless steel. the biggest risk from aluminium welding is Ozone, this is a problem with most welding. Its is well worth reading on the website but I feel that for most hobbyists its not going to be a huge risk as long as they are working in a well ventilated area. Otherwise get an extractor.

All our fluxes have been changed here recently for health and safety reasons and don't work as well as they did. I get more noticable acrid fumes from the new aluminium flux now so not so sure of the health benifits.
