MACHINABLE CAST RON AC-DC

machineable welds on all cast irons

GENERAL APPLICATIONS: Cylinder Blocks o Crankcases o Valve Seats e Defective

Castings o Gears o Sprockets e Casting Repairs in General o Garages o Farms o Shops

3/18"

130-175

DESCRIPTION

This electrode uses a nickel core wire, and produces a fully machinable weld without

pre-he._ting the casting, Cast irons can be joined to steel, nickel alloys and copper,

This electrode operates with AC or DC (reverse polarityL It has very stable arc

characteristics

It is recommended for automotive repairs, such as cylinder blocks, crank cases, valve seats

and other cast iron parts In maintenance and repairs it is used on gears, sprockets, and

many farm machinery parts

WELDING PROCEDURE: Remove all dirt and grease from work piece before starting to

weld, A cutting electrode may be used to burn a groove along the break where the weld is

to be made This cutting electrode removes the grease and scale, and then seals in any oil

soaked into the cast iron

Use the lowest amperage that gives good fusion During cooling, peen hammer the weld to

relieve strain and stress

CUTTIING ROD AC-DC

quick, inexpensive, easy cuts through all metals

GENERAL APPLICATIONS: Cutting e Piercing _ Gouging = Scarfing o Beveling = etc

SIZES AND HEATS (AMPS)

Diameter ...... 3/32" 1/8" 3/16"

Amperes- AC 80150 75-130 130-175

Amperes- DC 150-250 -

5/32"

100o150

DESCRIPTION

For piercing, gouging, cutting, and scarfing

Excellent for removing old welds in preparation to rewelding_ Also used for beveling

cracks in castings or removing sharp edges prior to welding Needs no oxygen or special

equipment to cut carbon steels, stainless steel, manganese steel, cast iron, etc

Recommended for the owners of all arc welders_ AC or DC

WELDING PROCEDURE: Place etectrode in holders so that it's positioned like a lance in

the direction of travel The angle between the electrode and work metal should not

exceed 15° Strike arc at starting point, Push electrode along the line of cut, forcing the

molten metal ahead and away If deeper gouge is required, repeat procedure untg the

desired depth has been reached
