AB-1 Cast Iron Welding flux removes all impurities in the weld metal. It prevents the formation of oxides and eliminates blow holes, providing a more granular and ductile weldment.

Description
Anti-Borax No. 1 is a welding powder flux that is active in the temperature range of 815°-1540°C/1500°-2900°F. This flux is used to weld cast iron with a cast iron rod. Anti-Borax No. 1 promotes deep penetration of the joints, resulting in high bond strength. The formulation is fluoride-free.

Applications
Anti-Borax No. 1 is used in the following applications: farm machinery repair, engine repair, and maintenance.

Directions
The base metal should be cleaned thoroughly to remove dirt, grease and other contaminants. Anti-Borax No. 1 may be used in a powder form or mixed with water to make a paste. Brush flux onto the work area, preheat filler metal rod and dip into the flux, then weld as usual. Flux residues are soluble in hot water at 60°C/140°F or hotter.

Safety Precautions
Anti-Borax No. 1 contains Boric Acid and should only be used in well ventilated areas. Avoid breathing dust and fumes produced during welding. Avoid contact with skin, eyes and mucous membranes. In case of eye contact, flush freely with water and call a physician. Keep away from heat, moisture and water, as they reduce shelf life. Return flux to sealed container to prevent caking.
