[TheForge] Aluminum Gas Welding flux

Sat Feb 16 09:47:00 2002

Hey Cameron,
  I got some oxy-acetylene aluminum welding flux from the guy I bought my
Henrob torch from several years back...as I recall it works pretty good
(been a long time since I welded aluminum woth anything but TIG).  I'll
check the brand for you later today if you're interested.
George.
