I would have to disagree with this statement.
I have been gas welding aluminum for years.

Welding Aluminum with Oxy/Acet DOES NOT work due to the impuritys from
the enviornment entering the weld area. Tig or Mig are used
specifically for the reason that it has a shield of inert gas such as
Helium or Argon surronding the Stinger wich keeps impuritys out of the
weld area.
