DESCRIPTION
The Medium Chrome-Carbon rod is a hard-surfacing alloy steel electrode with a coating of powdered me_als
and flux When welding, th=s special coating combines _n the arc with the steel core wire to give an
extremely hard weld-metal deposit Deposited weld metal requires no heat treatment for maximum
strength, duetdlty, and wear resistance Anneahng or heat treating wdl not soften the metal deposit, which
is not machinable, but may be hot forged to any desired shape. Oepos=ted metal has a very fine gram and is
free of slag and porosity The metal _stough and h_ghly resistant to wear and ,mpact
The rod =s designed for use wJth eltber AC or DC (rather DOlarlty). Hold a medium short are and deposit the
metal w_th a weaving motion Excellent welding results are obtained =n eJther the vertical or flat positron
WELDING PROCEDURE: Grind the surface to clean and remove shallow cracks, rust, or other foreign
material Cracks too deep lco 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 wfder bead,
or use a"free" arc
