DESCRIPTION

The Medium Chrome-Carbon rod is a hard-surfacing alloy steel electrode with a coating of powdered metals

and flux. When welding, this special coating combines in the arc with the steel core w,re to gwe an

extremely hard weld-metal deposit. Deposited weld metal requires no heat treatment for maximum

strength, ductility, and wear resistance. Annealing or heat treating will not soften the metal deposit, which

is not machinable, but may be hot for£ad to any desired shape. Deposited metal has a very fine grain and is

free of stag and porosity. The metal is tough and highly resistant to wear and impact.

The rod is designed for use with either AC or DC (either polarity). Hold a medium short arc and deposit the

metal with a weaving motion. Excellent welding results are obtained in either the verticat or flat position.

WELDING PROCEDURE: Grind the surface to clean and remove shallow cracks, rust, or other foreign

material. Cracks too deep to be removed by grinding should be gouged out with a cutting torch or cutting

rod. Use the "drag" technique to deposit weld metal, to thin edges when desirable or weave a wider bead,

or use a "free" arc.
