 TYPE: BRAZING - TORCH
PROCEDURES:
(flux-coated rod for general brazing)
Clean joint and bevel heavy sections. On cast iron, use
an excess oxygen flame to sear the weld area to a blue

heat. Preheat heavy sections to 800F. Apply flux
9GD 3439-00-165-4197 (3/16X 18)
Melt off a drop of the rod and flow it out - continue to

add more alloy drop by drop.
USES:
Joining of steel and cast iron and most copper-based
CHARACTERISTICS :
metals, such as brass and bronze. Can be used on
