The FBW Welding Kit is available in a variety of sizes and voltage/power ratings. The model number indicates
the width of belt that may be welded on a 90° joint. For example, the Model FBW 301 welds a 300mm (12”) wide belt
and the model FBW 1301 welds a belt that is 1300mm (51”) wide.
Models 301, 721, 1061 and 1301 may be operated by one person. The FBW 1701, 2101 and 2301require two
operators for correct and safe operation because of the length and weight of the Welder. The FBW Welding Kit is
supplied in a storage case to store the system components. Store only the FBW Welding components in this box to
avoid damage of the items.

2.2. The Storage Case
2.3. The Electrical System
Electrical Shock Hazard - Never remove the ground from the power cord or
internal wiring.
2.4. Care and Maintenance
The storage case is meant to protect the tools against dirt and damage during transportation. The case is designed to
store the entire FBW system. Tools and other items that do not belong to the FBW Welding System should not be
placed in the storage case. Loose, unsecured items may move around and damage the Teflon coating of the Welder.
Do not store chemicals in the FBW storage case - chemical fumes and possible spills may damage the wiring and
internal components
of the Controller.
All metal parts of the FBW Welding System are grounded. Ensure that the electrical plug is connected to a power
source with an earth ground and a Residual-current device (RCD). The thermo-couple wires must not be disconnected
as this will cause uncontrolled heating and damage the Welder.
Keep the system dry and clean.
Occasionally apply a light coating of oil to sliding metal parts.
The quality of the finished weld is affected by the condition of the Welder. To obtain the highest quality results from your
Welder, always wipe the Welder’s flat surfaces with a clean cotton cloth to remove material and dirt immediately after welding.
When welding is completed, return the tools to their storage box. There is no need to wait for the Welder to fully cool
down. The partitions inside the box will ensure that the system does not move during transportation and guarantee the
tool’s long lasting functioning.
The Welder must be cleaned while hot. Because the temperature of the welder
is high, extra care must be taken to avoid burns. It is recommended that you
wear protective gloves.

you.
b.
c.
d.
Apply strips of good quality double-sided tape on the
upper surfaces of the Pliers’ jaws.
e. f.
3.2. Preparing the Pliers
Connect the Welder to the Controller, and then connect the main power to the
power supply. Turn the Power Switch to “ON” and allow 15 minutes for the
Welder to warm up and the temperature to stabilize. The Welder is supplied
after factory adjustment and should not be altered unless there is a problem.
The Temperature Controller should be adjusted to 220°C (428°F) for all belt
types. If you need to readjust the temperature, please refer to Page 32.
Position the Locator Bar between the jaws of the
Pliers. Place the Locator Bar in the center of the
Pliers and over the Pliers Shafts. The belt locator has
reference marks for belt alignment, Each side of the
Belt Locator Bar has notes for different belt
thicknesses. One side is marked for 1.5 to 2.5 mm
belts and the opposite side for 3 to 5 mm belts.
Ensure that you have the correct side facing up.
Move the Operating Handle to close the Pliers jaws
and lock in place using the Locking Lever. (By pulling
the lever up you can adjust the handle position).
Loosen the 4 knobs securing the Crossbars. The two
knobs closest to the Operating Handle are hinged
and can be swung out and down to remove the
Crossbars.
Remove the Crossbars and set them aside. FBW
models 1301, 1701 & 2101 are equipped with magnetic
crossbars. To remove these crossbars, slide or roll
them off the Pliers.

Cut the two ends of the belt at 90°. Ensure that the
cut is accurate and straight.
b.
c.
d. e.
f. Open the Pliers and remove the Locator Bar. Leave the
Pliers open The system is now ready for welding.
3.3. Preparing the Belt
Clean the belt ends with denatured alcohol. The
belt ends must be free of dirt and grease in order to
ensure a consistent, high quality weld.
Remove the protective paper from one piece of the
doublesided tape and place one end of the belt against
the Locator Bar in line with a reference mark. Press the
belt onto the tape to ensure good adhesion. There
should be no gaps between the belt edge and the
Locator Bar. Gaps will produce an inconsistent weld
and lead to early failure of the weld.
Repeat this procedure for the opposite belt end. Make
sure you align the edge of the belt with the reference
mark on the Locator Bar, to ensure a straight edge
between the two ends of the belt.
Set the Crossbars in place and swing the Locking Bolt
into position. Finger tighten the nuts. Be careful to
apply even pressure on Crossbars. Uneven pressure
will allow the belt to shift during welding and too much
pressure will cause the Crossbars to bend.
Note: If the belt is narrow in comparison
to the tool, add belt pieces to each side
of the belt to fill the gap. This will prevent
bending of the crossbar.

Clean the belt and Welder. With the Welder cable
away from the operator, place the pre-heated Welder
between the two edges of the belt. Position the
Welder over the Pliers guide bars.
Using the Operating Handle bring the two belt ends into
contact with the Welder. Apply very gentle pressure
and observe the melting of the material along both
sides of the Welder. Do not hold the Welder during the
welding process. The Welder should be free to move
with the belt. When the material is evenly melted along
the length of both sides of the Welder, move the
Operating Handle to open the Pliers. Quickly remove
the Welder and close the Pliers. This operation should
be performed quickly but without too much force.
With the belt ends pressed together, lock the Adjusting
Lever. The weld requires approximately 5 minutes to
cool. The time required for cooling depends on the
thickness of the belt and the ambient temperature.
When removing the Welder, pull it straight up in a quick
movement. This will prevent the welder from pulling
melted material off of the belt ends.
The cooling process can be sped up by directing
compressed air along the weld.

www.voltabelting.com

Clean the Welder using a clean, dry, lint-free soft Cotton
cloth while the Welder is hot. Leaving material on the
Welder will damage the Welders surface and reduce the
efficiency of the Welder and the quality of the welds.
Separate the belt from the Pliers and turn it over placing
the trimmed surface on the Pliers. Trim the excess from
the bottom of the belt.
Check the splice quality by bending the belt in both
directions. Check the quality of the splice across the
width of the belt and on both sides. A good weld will be
free of cracks and defects. In case of a bad splice repeat
the above steps (this will cause the loss of about 5 mm
of the belt’s length).
The amount of pressure required to secure the ends of the
belt depends on the thickness and type of material being
welded.
During welding, air bubbles are formed in the melted ends.
The bubbles should be pressed out during the operation.
If too much pressure is applied during welding, the heat will
penetrate only a very narrow section along the edge of the
belt. When the Pliers are closed this small amount of melted
material will be pushed out. To ensure a quality weld, the
heat must penetrate a wide section of the belt.

Ensure that there is an offset of 1 mm. This offset will
compensate for the material melted during welding and
ensure a smooth Straight edge.

7. Instructions for Welding H Material Belts
6. Instructions for Welding Narrow Belts
The FBW models 301, 721 and 1061 can be used to weld narrow belts from 150 mm, by using double-sided tape
and without assembling the Crossbars. Observe the following rules:
a. Use good quality tape and make sure it is thoroughly adhered to the Pliers.
b. When welding reinforced belts, work upside down with the fabric facing upwards.
c. If the belt still moves while welding, raise the welding temperature by 15°C to 20°C to allow an easier melting of
the material and reduce the pressure required. When you finish, return the Temperature Controller to 220° C.
The procedures for welding M and H family materials are basically the same. However when welding H family belts
it is necessary to be extra careful. The following are specific areas to watch out for:
a. When welding H material belts, and especially belts 4 mm thick or more, in ambient conditions of low
temperature and high humidity, it is necessary to warm the belt ends before welding.
b. With the belt ends secured in the Pliers, use a Leister Hot Air Gun to direct hot air over the belts’ ends for
approximately 2 minutes.
c. Without delay continue with the standard welding procedures described above.
d. If you do not have a Leister Hot Air Gun, you can place the Welder in the Pliers over the Pliers supports. Close
the Pliers without bringing the belt ends into contact with the Welder at least for a minute. The heat from the
Welder will warm the belt ends before you begin to weld.
e. When you bring the belt ends in contact with the Welder, press gently until the two ends have an even melt
along the entire length of both sides of the Welder. At this point stop pressing and maintain this position for
approximately 20 seconds. This allows the heat from the Welder to penetrate farther into the “H” material providing
a sufficiently large softened area to ensure a good weld. Open the Pliers quickly and with a “snap”, which will
prevent material from sticking to the Welder.
Release pressure, remove the Welder continue with the standard welding procedures described above.
f. Using the Operating Handle, quickly close the pliers, because the H material cools down quickly. When working
with H material belts, especially those that are 4 mm or thicker, apply extra pressure when closing the belt. This is
needed to force any air bubbles out of the joint. However, remember that applying too much pressure will reduce
the quality of the weld by forcing all of the melted material out of the area of the joint and leaving only cold
material.
g. The splice must be left to cool for at least 10 minutes after welding. Checking the splice by bending it too soon
will weaken or break the splice.
h. Because of the care needed to ensure a quality weld, it is important to perform several trial welds before
welding a belt. This will allow you to get the feel for the pressure required while welding and closing the Pliers after
welding. If you still have problems, please contact Volta for aditional technical advice.

Tip. Use double sided tape on the bottom side of the cutting bar to prevent
slippage while cutting.
Reposition the cutting bar make a clean cut using a
sharp knife. When cutting the SD, we will have 2
ends one usable and one unusable (Photo 4, 5, 6)
this is due to the fact that we did not cut in the middle
of the pitch.
Use the Cutting Bar to cut the belt between the teeth,
to ensure a 90º cut and the correct pitch. Push the
cutting bar away from you and then against the right
side until the single tooth stencil fits exactly in line with
the tooth, giving you a perfect 90º position for marking
your line.Draw a line and then check that the line is
parallel to the teeth. Photo’s 2 & 3. When cutting the
belt this line will help us to make sure that the cut is
square.
The cutting bar is marked with positioning arrows as
per photo 1.
