For All Silflo® Alloys
Clean joint area. Jigs and fixtures
will help hold parts in place. Paint brass and bronze parts with All-State®
No. 110 or
S-200 Flux. Use a large tip, heat broadly until flux liquifies or copper turns
dull red. Apply sufficient alloy to fill joint.
Do not overheat or remelt. Submerge in hot water and brush to remove flux. Ten
percent sulfuric acid and water
solution will restore copper color. Rinse with clear hot water.
