PROCEDURE:
Rough grind surfaces to be joined or built up. Paint surfaces to be joined and protected from oxidation with MG
130F flux. When using flux coated rods it is not necessary to use the paint-on flux unless additional protection
is required. Always use a neutral flame concentrated on the base metal, not on the molten alloy. Keep torch in
constant motion to prevent overheating of local areas. When used as a joining alloy small rods are
recommended but for surfacing and build-up the larger diameter rods should be used. Additional passes can
be applied without the need of removing flux residue from previous passes. Allow part to cool slowly. Remove
flux by chipping and wire brushing.
