#73 Aluminum Welding Flux
This flux produces a strong,
non-porous weld by keeping the base metal and rod free of
oxides during welding.
Sizes: 1/4 lb - 1/2 lb - 1 lb
Uses:Use for welding aluminum and alloys. Recommended for
use with #4043 Bare Aluminum. Mix with water to form a paste and
apply to both rod and metal. After welding, remove residue
with warm water. Basically use the same as #71 except that
heat is applied to base metal.
