MG 6316 - 16
SLIK - STIK
STAINLESS
ELECTRODES
GENERAL CHARACTERISTICS:
These alloys have a high molybdenum content to give them additional strength, even at high temperatures and to provide extra corrosion resistance to certain acids. The high quality, balanced
chemistry of these electrodes gives them superior welding characteristics. They are designed with a
special spray type arc transfer. This results in less heat input because a closer arc gap can be
maintained while welding. This also makes it an easier electrode to use in all positions. MG 6316 and
MG 6316L have arc stabilizers in the coating that make them outstanding when used on AC machines. The slag is very easy to remove - virtually self-lifting. The special coating ensures, dense,
porosity free deposits.
APPLICATIONS:
MG 6316-16 is designed to weld type 316 stainless steel. This group has molybdenum added to
increase its corrosion resistance and creep strength at elevated temperatures. Chemical plants,
pulp and paper, and textile dyeing industries use this alloy because of its resistance to corrosion
from sulfite liquor solutions. Also used in petroleum refinery equipment and phamaceutical equipment, as well as photographic equipment, food processing equipment and nuclear equipment. MG
6316L-16 is used on 316L grades of stainless steel or where carbon content must be low, also for
CF-3M, CF-8M castings.

PROCEDURE:
Clean weld area of foreign material. A 60° bevel is used when welding parts 3/16” or heavier. DC
reverse polarity is preferred. Use lowest amp setting possible to get good bead contour which is
usually about 20% less than for mild steel. In fabricating, tack weld at close intervals using next
smaller diameter electrode. Chip slag and stainless steel wire brush tacks before welding. Use
stringer beads where possible and keep close arc gap while welding. Avoid excess heat build-up.
Thin sheets may have to be clamped with chill blocks to avoid excessive distortion.

as a jigging fixture or insulator for parts to be welded. Extra Hands will not distort or shrink
when heated.
APPLICATIONS:
Can be used as a heat sink to absorb heat and avoid surface discoloration on heat sensitive parts. It can be used as a heat dam to prevent heat from traveling to areas that can be
damaged by heat, such as O-rings, packing glands, glass, and paint. Extra Hands is ideal
to hold or position difficult to align parts. Extra Hands will keep distortion down when welding on light gauge metals such as stainless steel.
TECHNICAL DATA:
- Asbestos free - Does not contain any toxic elements.
- Maintains shape when heated.
- Withstands temperatures to 3000°F.
- Can be reused.
- Can be reconstituted using water.
PROCEDURE:
Position each of the parts to be joined in a mound of Extra Hands large enough to support
its weight. Adjust the alignment as necessary before welding. If parts need to be protected
from heat, cover that area with a thin layer of Extra Hands. For high temperature applications or where heat is applied for a prolonged time, use a thicker coating. Extra Hands can
also be used to protect non-metallic parts alongside the welding area. If moisture would be
harmful to the protected area, a piece of plastic wrap should be applied first.

Copper & Nickel Alloys
A specially developed flux used in conjunction with MG 120 Solder silver tin alloy, primarily
designed for the joining of stainless steel components within the food kitchen utensil and
medical industries. An active chloride / floride bases flux offering ease of tenacious oxide
removal, especially chromium oxides on stainless steels. Also suited for copper and its alloys
and nickel alloys.
APPLICATIONS:
Combined with MG120 Solder they’re commonly used to join a variety of ferrous and nonferrous metals when higher strengths are required than normally found with conventional solders.
Ideal for use on stainless steel, brass, bronze, copper, nickel, nickel alloys, and carbon steels.
Typical applications are food and dairy equipment, instruments, oxygen lines, sanitary apparatus, and general maintenance repair.
TECHNICAL DATA:
Active Temperature Range ............................................................. 350º F to 500º F
Form ............................................................................................... Paste or Liquid
Container Size ......................... 8 oz. Jar for Paste, 4 oz. and 1 Gallon Jar for Liquid
PROCEDURE:
This flux, when heated, will commence to melt at soldering temperature, the melting takes the
form of a “bubbling” effect which indicates the temperature at which MG120 alloy should be
applied.
Flux Removal:
MG 120 flux residues should be removed once the solder alloy has solidified by washing with
the aid of a stiff wire brush in warm water. Where components have become cold prior to
washing, remove residues with the aid of hot water. Flux residues may, if required, be removed
with the assistance of a chemical wash, the following steps are recommended.....
1) Wash in hot water for 12-15 minutes.
2) Wash with a 1% hydrochloric acid for a few minutes.
3) Followed by an alkaline solution wash in order to neutralize
any entrapped acid in the joint.
4) Wash in hot water 10-15 minutes.

RESISTANT BUILD-UP
TORCH OR INDUCTION
Premium alloy available both bare and flux-coated for general maintenance repair with the
torch. At 1400°-1600°F the deposit has controlled fluidity which makes it ideal for surfacing
and build-up of parts subjected to frictional wear. When the temperature is increased to
1650°-1750°F the alloy becomes very thin flowing and will produce high strength joints with
only .001” to .003” clearance.
APPLICATIONS:
1. Low temperature-overlaying and build-up of gear teeth, bearings, shafts, valve seats,
wedge bars and steering knuckles.
2. High temperature-for close fitting joints on broken drills, mill cutters, furniture and
bicycle assemblies, attaching carbide cutting tips and many other applications requiring
high strengths.
This alloy is designed to build-up and join carbon steels, alloy steels, cast iron, and many
non-ferrous materials to themselves or multiple combinations.

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.

SUPER STRONG GENERAL
PURPOSE BRAZING ROD WITH
PRECISION FLUX CONTROL
GENERAL CHARACTERISTICS
Premium alloy for general maintenance repair with an Oxy /Fuel Torch. With the unique
concentrated flux imbedded in the surface of the brazing rod, the welder will no longer have
to fight through excessive flux to put down a perfectly brazed joint. At 1400°-1600°F the
deposit has controlled fluidity which makes it ideal for surfacing and build-up of parts
subjected to frictional wear. When the temperature is increased to 1650° - 1750°F the alloy
becomes very thin flowing and will produce high strength joints with only .001” to .003”
clearance. The P.F.C. (Precision Flux Controlled) will in most instances cut brazing and
clean up time in half. These are extremely important factors when dealing with cost
conscious welders or companies.
APPLICATIONS:
1. Low temperature- overlaying and build-up of gear teeth, bearings, shafts, valve
seats,
wedge bars and steering knuckles.
2. High temperature- for close fitting joints on broken drills, mill cutters, furniture and

welding. Preheat to approximately 400°F (204°C) on very heavy sections. Use short stringer
beads for root pass and peen lightly after removing slag. Use the lowest amperage possible
and maintain a short to medium arc to minimize base metal overheating. Always fill the crater
and drag rod back over the weld deposit when breaking the arc. A weave of two times rod
diameter is acceptable for cover beads on multi-pass work.

(AWS E308-16)
(AWS E308L-16)
MG stainless steel electrodes are balanced chemistry electrodes that have superior welding
characteristics. They are designed with a special spray type arc transfer that results in less heat
input because of the closer arc gap that can be maintained while welding. This also makes them
easier to use in all positions. The arc stabilizer used in the coating make them outstanding when
used on AC, particularly with limited duty cycle, low open circuit voltage AC machines. The slag is
virtually self-lifting. The special coating insures dense porosity free deposits.
APPLICATIONS:
For fabricating and repair of types 201, 202, 204, 301, 304 and 308 stainless steel. These
electrodes are used where service conditions are not severe. Generally used on large fabricated
parts involving high volumes of welding, dairy and restaurant equipment and chemical tanks; also for

PHOSPHOR (TIN) BRONZE
ELECTRODE FOR APPLICATIONS
SUBJECTED TO FRICTIONAL WEAR
Both AC and DC types have smooth arcs that produce dense, porosity free deposits in all
positions with a minimum of spatter. Welds have excellent color match to bronze. Slag is
easy to remove.
APPLICATIONS:
Due to the nickel content, the DC electrode deposits are harder and more wear resistant than
the AC deposits. The AC electrode should be used when “arc brazing” galvanized sheets or
when color match and machining are required after welding. MG-320 DC electrodes are
preferred for higher strength joining and cladding of bronzes, brass, steel, and cast steel.
Both electrodes offer good resistance to sea water and many other chemicals. Common
applications are repair and surfacing of gearwheels, bearings, pumps, impellers, turbines,
valve bodies, and defects in new castings.

joining thin sections, the joint should be square groove (a space between edges). On
thicknesses between 3/16” and 3/4”, use a single V joint. On thicker sections, use a double
V joint. It is advisable to keep the weld puddle as small as possible to assure rapid solidification of deposit. When using MG-382 with oxy-acetylene, use a slightly oxidizing flame. It
is essential that MG-130 flux be used with the oxy-acetylene process. Welding can be done

ALUMINUM BRAZING ALLOY
TORCH OR TIG
Specially alloyed for use with torch or TIG on all known weldable and brazable aluminums.
It is not necessary to melt the base metal when using this product because it works similar
to silver brazing alloys that are very fluid. Deposits have good color match to aluminum,
high strength, and good electrical conductivity.
APPLICATIONS:
Ideal for joining thin wall tubing, sheets, and extrusions. Commonly used to manufacture
and repair furniture, truck bodies, window frames, instruments, and appliances.

Unique aluminum torch alloy with the highly active flux contained inside the rod where it is
protected from contamination. It can be applied in all positions with the oxy/fuel torch.
Tungsten inert gas, DC welding machines, and other expensive welding equipment are not
needed for the repair of most aluminum parts; therefore this rod fills the needs of many
welders both in the shop and field.
APPLICATIONS:
Fabricating, build-up, and repair of all weldable grades of aluminum, including cast alloys.
Ideal for joining dissimilar gauges and for poor fit-up applications where a less fluid alloy is
desired.

LOW TEMPERATURE SOLDER
FOR ALUMINUM
TO ITSELF OR OTHER METALS
ALL HEAT SOURCES
A special complex alloy system solder that has excellent wetting and flow characteristics on
almost all ferrous and non-ferrous metals. Since it has a “0” plastic range, its strength
remains relatively high even at service temperatures up to 350°F (175°C). This solder has
better corrosion resistance and higher strength than ordinary soft solders, but the bonding
temperature is much lower than the silver brazing alloys, therefore it is the ideal intermediate alloy for joining.
APPLICATIONS:
Aluminum radiators, aluminum tube to copper tube in refrigeration and air conditioning
units, sheet metal work, manufacture and repair of instruments, zinc base die casting and
joining of dissimilar metals. Also for use on anodized aluminum.
TECHNICAL DATA:

High zinc content gives this alloy good color match to aluminum. Other alloying elements
are added to give high strength and low working temperature. Since no flux is used, post
cleanup is eliminated. Warpage, distortion, and discoloration of the work is prevented by
the low working temperature.
APPLICATIONS:
Ideal for joining aluminum extrusions used in the manufacture and repair of aluminum
doors and windows. Also repairing ladders, gutters, siding, aluminum boats and instrument
boxes. Most kirksite and zinc base die castings can be repaired with this alloy. May also be
used as a wearfacing alloy on aluminum.

THE ULTIMATE ELECTRODE FOR

WELDING ALL TYPES OF STEELS,
“SUPER” WITHOUT ANY DANGER OF
CRACKING OR BREAKAGE
600
Because maintenance shops often have old or inexpensive welding equipment, “Super” 600 has
been formulated to provide the best possible arc stability, even under adverse conditions. It is
amazingly stable on low, open circuit voltages, AC buzz boxes. The weld metal transfer is especially
smooth and there is almost no spatter. Arc restrike is instantaneous. We have even managed to
make the slag virtually self-releasing. It is without doubt the best possible product to use on unknown steels and dissimilar metal combinations.
APPLICATIONS:
Due to its exceptional strength and crack resistance, it is ideal for repairing tools, dies, spring steel,
and any dissimilar metal combinations, with the exception of the aluminums and copper alloys.
Because the weld metal is so tough, it is also recommended for repairing worn parts, and also as
an underlayment for hard facing. Because of its low amperage requirements and exceptional ease
of its use, it should be the first choice for both home hobbyists and maintenance welders for general
applications.

PROCEDURE:
Preparation: Clean weld area of scale and/or oxide. Make sure all oily contaminants are removed with a suitable VOC cleaner. Angle
preparation normally involves close-butts, and infrequently bevel preparations. If needed, a 60º V bevel is acceptable. Pre-heating of
stainless steels is generally not required. In the case of dissimilar steels preheat carbon steel parts to a nominal 200ºF to 250ºF. DO NOT
HEAT MANGANESE STEELS!
Technique: A short, non-contact technique is recommended for both fillet and butt-welding. Use a slightly longer arc-length for beadon-plate welding. Deposit stringer beads or 2x to 3x weave beads. Do not weave more than three times the electrode diameter
otherwise excessive heat input will cause distortion.

hardening). Maraging at 450°C for 2 hours produces a hardness of RC 48-52. Maraging
steels do not require preheat; other steels should be preheated to their recommended
preheat temperature prior to welding.
APPLICATIONS:
Build-up and repair of hot working dies and tools made from maraging steels used in
aluminum and zinc die casting industry. Use for build-up on H-11 and H-13 tool steels
when machining in the as welded condition is desirable. When used in aluminum and zinc
die casting dies, deposits will harden in service.

WELDING ELECTRODE FOR
H-13 TOOL STEELS
MG 713 is a chromium, molybdenum vanadium electrode designed to weld H-13 tool steel
and build-up H-13 deposits on other steels used in tools and dies. The weld deposit of MG
713 is similar in chemical composition, mechanical properties and response to heat
treatment to H-13 tool steel. Heat treating procedures for hardening, tempering and
annealing for H-13 are suitable for MG 713 weld deposits. Since base metal and weld
deposits have the same chemistry and mechanical properties, unwanted structural
changes in the HAZ (heat affected zone) after welding are minimized.
APPLICATIONS:
Build-up and repair of tools and dies made of H-13 steel. For making working surfaces on
composite dies when characteristics of H-13 are needed. Use to correct machining errors.

sections and hardened steels to 400°F-600°F (200°C-310°C). To prevent excessive dilution
with the base metal, two thin layers are recommended instead of one thick bead. Maintain
a medium arc length. Direct arc on previously deposited weld metal. Stringer or very narrow wear beads should be used. Cool slowly. Deposits can be finished by grinding. For gas
welding, a neutral flame should be used to preheat the workpiece. When the sweat or
brazing heat is reached (just before the red starts to show), apply a small amount of MG
780 to set or tin the surface; then add more alloy to buildup using a bead forming technique.

PROCEDURE:
Remove old welding deposits and worn metal with MG 570. Round of sharp corners. Preheat
the base material to proper temperatures, which should be determined based on thickness, as
well as carbon and alloy content. On hardening and self-hardening steels it may be necessary
to apply a buffer layer consisting of two passes of the MG 620W to act as a “cushion”. Once
the arc is struck, work the arc in a circular weaving pattern to obtain a regular and compact
deposit. Maintain an arc length of approximately 1 ½”. Too long an arc can reduce the mechanical properties of the deposit.

A SUPER ABRASION RESISTING
COMPOSITE TYPE ALLOY THAT
DEPOSITS EXPOSED TUNGSTEN
CARBIDE CHIPS.
This composite type rod is made up of easy to wet, super hard, sharp tungsten carbide particles
that are held in a shock resisting matrix that also has extra holding strength to keep these carbide
particles from coming off, even under extreme conditions. Can be used on steel, cast iron, and
copper alloys. When the exposed carbide chips become dull, they can be heated and repositioned
to expose new, sharp edges to help reduce application costs. Available in various size tungsten
carbide chips.
APPLICATIONS:
Used to overlay drills, reamers, bucket teeth, augers, stabilizers, milling tools, or any parts that must
take severe abrasion. Used extensively in the oil and earth moving industries where abrasion
resistance as well as good impact qualities are important. Can be used to surface horseshoes to
prevent slipping, or on any part that needs a rough surface. Can also be used in the agriculture and
dredging industries on mill hammers, plow shares, cultivator shovels, dredge bucket lips, dredge
pump cutters, side pump plates, and drive tumbler plates. It can be used in the brick and cement
industries for crusher rolls, muller plows, shredder knives, pug mill knives, pipe forming shoes, etc.

PROCEDURE:
Clean the surface to be overlayed. For best results, first deposit a thin layer of MG 130. Previously
overlayed areas need no special treatment or tinning, as MG 788 will adhere perfectly to itself.
Preheat the area to about 600°F before tinning, deposit carbides and matrix to the desired width
and thickness, placing the carbides where they will be most effective. Be sure to keep the area
fluxed with MG-350 Flux to insure good clean deposits. To rejuvenate dull carbide chips, flux the
deposited surface, heat until the matrix becomes semi-molten (mushy). With a steel rod, push at
the carbides to reposition them until sharp edges are exposed.

A SUPER HIGH ABRASION
FUSEKOTE RESISTING TUNGSTEN CARBIDE
BEARING ALLOY
1075
Fusekote 1075 has a very high percentage of large tungsten carbide particles in a hard
nickel base matrix. The amount and size of the carbides make it the ultimate in abrasion
resistance. The deposits of 1075 are sharp and gritty for applications that need a gripping
surface. Thicker deposits tend to be smooth because the heavier tungsten carbide
particles settle lower in the thick deposits. As the deposit wears down, the carbides
are exposed and wear almost stops.
APPLICATIONS:
Fusekote 1075 is used where exceptional abrasion resistance is needed, especially in heat
cycling or corrosion resistance situations. This alloy, when deposited as a thin layer, leaves
dense, coarse tungsten carbides protruding making it ideal as a surface for take-up and
in-feed rolls; also ideal for building up edges or any fast wearing parts of tools. Can be
used on steels, cast iron, stainless steel, nickel and nickel alloys.
TECHNICAL DATA:
Fusekote 1075 is a heterogeneous alloy with a high nickel, high chromium matrix
containing the optimum amount of coarse tungsten carbide.
Matrix Hardness ............................................................................................ Rc 64
Tungsten Carbide Particle Hardness............................................... Approx. Rc 70
PROCEDURE:
alloy out. If a thicker deposit is required, repeat the process. If a gritty surface is needed, a
very thin coating should be applied so that the tungsten carbide particles can protrude from
the surface after it is wet out.
