GENERAL SAFETY INSTRUCTIONS
1. Always wear proper clothing, safety glasses and gloves when
exothermic welding.
2. Only weld items that the mold is designed for.
3. Do not use worn or broken molds which could cause leakage
of molten weld metal.
4. Always use proper handle clamps or frame work required for
the mold and make sure it is adjusted properly to close the
mold completely.
5. Make sure that the conductors being welded fit in the mold
properly and that the mold will close tightly around them.
6. Do not alter molds or accessories without factory
authorization.
7. Avoid breathing concentrations of smoke, as it may be
hazardous to your health.
8. Avoid contact with hot materials.
9. Remove or protect fire hazards in the welding area.
10. Avoid moisture and contaminants in the mold and conductors
being welded. Contact of molten weld metal with moisture or
contaminants may cause weld metal to spew out of mold.
11. When welding to pipe or vessels, you should consider the
following:
A. the effect welding may have on structural members and
thin wall pipe or vessels.
B. pipe or vessels that are pressurized or contain (or have
contained) flammable, explosive or hazardous materials
should be evaluated in the case of a melt through or hot
molten weld metal coming in contact with any
flammable, explosive or hazardous materials.
12. Failure to abide by the above and follow welding procedures
may result in improper welds, damage to the material being
welded or create hazardous situations for the individual.
PREPARATION OF CABLE
1. Cable must be bright, clean and dry.
2. Cable that is saturated with oil or grease must be cleaned.
Cable may be cleaned by burning it off with a propane or
oxy ‐ acetylene torch. After burning off oil or grease, a wire
brush should be used to remove residue. Wet cable must be
dried out. Use a hand propane torch.
3. Corroded cable must be cleaned. Use the CCBRSH2 cable
cleaning brush or CCBRSH1 card cloth brush. It is important
that the ends of the individual strands are clean. This can
best be accomplished by making a fresh cut on the end of
the cable.
4. Cable should be straightened before clamping mold in place.
Bent or out of round cable will hold mold open and cause
leaks.
5. Remove insulation from insulated cable before cutting with
hack saw. Otherwise, ends of strands will become coated
with insulating material which may cause defective welds.
6. FLEXIBLE CABLE: A sleeve must be used when welding
flexible cable. WRPSLV wrap sleeves are recommended for
300 MCM and smaller cable or check with factory for
premade sleeves.
PREPARATION OF GROUND RODS AND
GROUND RECEPTACLES
1. Ends that are threaded, mushroomed from driving, or
drilled and tapped, must be cut off before welding to the
end. Contact factory about ground rod driving sleeves.
2. The site of the weld on the ground rods and receptacles
must be clean. Use a coarse file to remove rust and oxide
before welding
3. Slightly UNDER SIZED ROD MAY BE BUILT UP WITH WRPSLV
WRAP SLEEVES. This will not work for large differences in
size.
WELDING PROCEDURE
1. Read all instructions and safety warnings before starting.
2. Check mold tag for conductors to be welded and proper
weld metal cartridge size to use.
3. Insert proper handles into the mold and lock mold shut if
applicable.
4. Make sure all surfaces and conductors are clean, dry and
are the proper sizes for the mold’s application per mold tag.
5. Molds can be dried by heating to approximately 250°F.
Molds may be dried with a hand operated propane torch or
by firing a charge in the mold before making the desired
weld.
6. Position conductor(s) into the mold. See front of this sheet
for positioning of conductors into mold. Lock mold with
handle clamps or frame, which ever is the case. Check to
make sure mold is completely closed.
7. NuwTube :
A. Insert steel disk being sure it is directly centered over
the tap hole. Failure to insert disk into mold will create
improper welds and spewing of weld metal.
B. Pour cartridge or cartridges into the crucible being
careful not to upset the steel disk.
C. Remove Orange bottom lid in NuwTube to remove
starting powder. Close lid and pour starting powder
into cup in the top of the lid, allowing some to fall thru
the ignition hole in the lid.
D. Ignite starting powder with flint gun. Pull flint gun
away quickly to prevent fouling flint.
8. UltraShot
A. Insert Ultrashot cup into mold crucible aligning metal
igniter with the small grove in the top of the mold.
Close lid.
B. Insert metal igniter into battery ignition cord.
C. Press both ignition buttons on battery pack while
standing clear of exhaust port on mold. Mold should
fire right away.
9. Wait approximately 30 seconds before opening mold to
permit metal to solidify.
10. To clean the mold, use a MCBRSH1 natural bristle brush,
soft cloth or newspaper before making next weld. Do NOT
use wire or plastic brushes to clean the mold!
11. On horizontally split molds, use end of mold cleaning spade,
a small diameter rod, or screw driver to remove slag from
tap hole. Caution should be used when cleaning molds to
avoid burns from contact with hot mold.
NOTE :
1. A fouled flint gun may be cleaned by soaking in household ammonia.
2. Proper weld metal cartridge size is marked on mold tag and shown on the cap of the cartridge tube.
3. Cartridge size is the approximate weight of the powder in grams. When the cartridge size specified is not available, two or more
smaller cartridges or part of a larger cartridge may be used.
4. Handle Clamp adjustments may be made by removing adjusting screw and turning eye bolt 180° clockwise to tighten or 180° counter
clockwise to loosen.
