The intended use of this strapping head is the bundling, combining and securing of
packing items in strapping machines.
Unintended use!
Strapping material must not be used for the hoisting of loads, this strapping head
may only be used as intended and specified above.
The strapping head VS-32-L meets German and European safety requirements and
complies with the provisions in the following EU directives:
See Declaration of incorporation!
The VS-32-L is the suitable strapping head for medium and heavy packing items;
it does not matter whether those items are steel or stone, wood or glass.
The VS-32-L combines most modern driving and control technology with the state of
the art of patented TIG shield gas welding technology.
All functions are released by solenoid valves. Valves are equipped with actuating
magnets 24 V DC (direct current voltage).
The mains voltage of the VS-32-L head is 400 V 50/60 Hz. The connected load of the
welding unit is 6,6 kVA. Protect by fuse 16 A (slow-blow).
The welding seal can only be opened by means of an appropriate tool (strap scissors or
the like). Sealing strength is at approx. 90 % of the load at rupture of the strap
(depending on strap quality and dimension).
Adjustable strap tension of 4000-20000 N permits a good adaptation of the strapping to
the packing item.
The strapping head can be supplied in the following designs: for strap widths of 19, 25
and 32 mm.
Power and compressed air feed lines have one detachable quick-acting coupling each.
The mechanical joint of the strapping head and the machine is possible at various fitting
surfaces by means of four M16 bolts at the bottom of the drive housing and two of them
at the top. If required, two further M12 bolts on the fitting surface of the holding device
on the right. After the loosening of the four screws and the disconnection of the electric
power and compressed air ports the head can be replaced quickly and without
problems.
VS-32-L 5
Page 6
B 13 GB 07/10
Three compressed air motors and two compressed air cylinder perform all functions of
the strapping head.
Just compressed air being dewatered, filtered and oiled is used. Air pressure
(flow pressure with transport motor being switched on) should be 6 bar. The port cross
section of the feed line must be G 3/4“ or greater.
Air consumption per strapping operation with conduit dimensions amounting to 2000 x
1000 mm is 0,2 to 0,3 m³. Consumption during the transport of strap is
1,25 m³/min. The short-time peak consumption is at 2,5 m³/min.
The argon/welding gas consumption amounts to 2 l per seal. When a 50 l gas bottle
with a filling pressure of 200 bar is used, approx. 5000 seals are possible, in case of
300 bar approx. 7500 seals. The welding electrode can be ground approx. 100 times.

the strapping machine.
Read instructions carefully.
Unauthorized individuals are not allowed to use the strapping unit
(machine)
It is urgently required that all safety and warning notes are
followed; we especially refer to the EU Machine Directive.
Before the strapping tool is put in operation, the machine area
must be locked such (protective fences / safety sensors) that
unauthorised individuals cannot get into the danger zone of the
machine.
The operating staff must be instructed precisely and made familiar
with the handling of the unit before operating the unit for the first
time.
The strapping machine may only be positioned and put in
operation in closed and dry rooms.
Operating the machine is appropriate in the temperature range +0
°C to +40 °C.
Do not deposit containers with liquids on the strapping tool or
strapping unit. No liquid must be allowed to penetrate the strapping
tool / strapping unit.
No persons or objects must stay in the area of operation of the unit
(machine) before the latter is put in operation.
Protective installations, covers and linings of the unit (machine)
must be checked before activation. They must neither be loose nor
have been removed.
Do not let your hands get into the channel area and below the
packing items during the strapping operation. Attention! Risk of
squeezing!

beginning of the strap is then inserted
into the guide rolls (306) until the
resistance of the conveying roller
(392) is sensed.
Following that, switch B9 on the
SEK01 is actuated, which then
triggers the lifting cylinder Z1 and the
transport rocker. Then the strap can
be slipped further.
After releasing switch B9 the rocker
lowers down and the strap is clamped
between conveying roll and counter
roller (420); therefore, it is ready for
the feed of the strap.
Should strap be inserted from a
greater distance, a switch for the lifting
of the conveying rocker has to be
provided at the machine!
Caution!
Use protective gloves when inserting strap.
7.1.2. Feed of strap, medium speed
At the tone of the start signal the 5/3-port directional control valve Y3 is selected.
The transport motor M1 is switched on and transports the strapping material
through the conduit system at 1,7 m/s, until the strap stop B1 is reached.
Simultaneously, a timer is processed (strap circulation control) which interrupts
the transport of strap when the maximum strap transporting time is exceeded
(breakaway of strap or resistances in the conduit).
Before the strapping head is reached switch B14 in the conduit is triggered: it
switches off the transport of strap fast movement Y2 and switches on medium
speed Y1.
The medium speed can be set on the pressure controller DR3.
Note!
When readjusting the medium section, the setting of the strap
tension is altered!

7.1.3. Strap feed, precise movement
The transport motor M1 then operates at reduced speed-mean speed Y1, until the
strap stop lever (87) has been reached which actuates the limit switch B1 and
again reduces the precise movement.
Simultaneously, counter switch B2 is activated. Switch B2 counts the pulses at
the transport shaft (385) prespecified and switches off the precise movement
during the transport of the strap after the strap overlapping has been completed.
In addition, a monitoring timer t9 is processed for strap overlapping. The
beginning of the strap is then found in the sealing sector.
7.1.4. Closing strap gripper 1
After the number of pulses prespecified has been reached, the solenoid valve Y5
of the sealing motor M3 is switched on, the sealing motor turns 50° and closes the
gripper (1671). During that operation switch ring 1 (55) leaves the zero position of
the sealing unit and the limit switch B3 (zero position = casing pitch and feather
key groove same level). Then after 50°, switch ring 2 (52) occupies Pos. K at
switch B4.
Then the beginning of the strap is secured against retraction. In most strapping
situations that position is chosen as stand-by position. From that position the
strapping head can be moved to the packing item.
A switching slide with two switches then sends the signal “Head before packing
item“ B7 to the control system, then, when the movement continues, it signals
"Head on packing item" B8.
7.1.5. Transport back of strap
With switch B8 (head on packing item) being assigned the 5/3-port control valve
Y4 is switched on for the transport back of the strap. The transport back remains
in operation until the strapping sling is around the packing item and the transport
motor M1 has applied a pretension of approx. 1800 N to the strap.
When the motor is in operation, counter switch B2 being screwed in the motor
flange (529) scans the speed of the motor (approx. 540 1/min = 1080) over two
surfaces on the transport shaft (385). A pulse monitoring device in the electronic
control switches off the motor when being at a standstill and starts the tensioning
operation.
After the transport back of the strap the valve air-cleaning device Y8 is switched
on for a short time t8 = approx. 0,5 s to remove abrasive and combustion residues
from the sealing cell.
7.1.6. Tensioning the strap
When the transport motor M1 is switched off, valve Y6 of the tensioning motor M2
and, simultaneously, the short stroke cylinder (314) of the rocker (330) over valve
Y16 are switched on. The rocker is lowered down to the strap and tensions it
around the packing item until the nominal value preset stops the tensioning motor.
The adjustable strap tension can be between 4000 and 20000 N. It can at the
multi-functional module (569) see chapter 8.4 being adjusted. The tension
pressures achieved can be read on the pressure gauge installed.
VS-32-L 24
Page 25
B 13 GB 33/06
7.1.7. Closing strap gripper 2
After reaching and maintaining the strap tension the solenoid valve Y5 is selected.
The sealing motor M3 moves 105° and moves switch ring 2 (52) to pos. W.
The clamping (47) grips both straps; simultaneously, gas valve Y10 is switched
on. Then, the strap fed is cut and pressed flexibly by means of the welded torch
holder (59). The closed strap gripper 2 is signalled via switch ring 2 by means of
switch B4. Simultaneously, a timer element t1 is processed which switches off the
tensioning motor M2 after the cutting and pressing of the strap.
7.1.8. Welding
After reaching pos. W the TIG automatic torches are ignited consecutively and
seal both ends of the strap. If no ignition of the first welding point, the 2
nd
welding
point will be set and the 1st will be repeated.
Welding time t5 and welding intensity t6 can be set in the control electronics.
Usually, a welding time of 1 to 1,5 s each at an intensity of current of approx. 160
A is satisfactory. The quantity of gas at the welding station should be set to 10
l/min (for setting see section 8.5). The time of the gas after-flow was set to 8 s by
the manufacturer.
The tip of the electrode should project 2 mm out of the gas nozzle. The distance
between electrode and strapping material should be 3 mm (for setting, see
sections 8.6 and 8.7).
7.1.9. Swivelling the welding station open
When the straps have been welded, the solenoid valve Y5 is switched on, the
sealing motor runs 160° to pos. F. In that situation switch ring 2 is assigned to
switch B4. The welding station swivels open by the curve (14) and releases the
welding seal.
7.1.10. Swivelling the welding station back
When the seal applies to the packing item, the strapping head can be moved to its
initial position. Simultaneously, the strapping material is retracted from the cutting
area. The sealing motor M3 is switched on and operates until the 0 position of
the head has been reached. The tensile springs (116) close the welding station.
Switch ring 1 (55) then occupies switch B3.
- A new strapping cycle may begin. -

7.3. Description of the welding operation
The TIG welding method is the tungsten inert gas welding method. This is a contactfree welding method. It must not be mixed with the so-called spot welding (with contact
electrode).
The weld is made contact-free by the electric arc under argon shield gas. This is a
commercial shield gas with a degree of purity of 99,996 % (argon 4.6).
Weld gas consumption amounts to 2 litre per seal argon gas. Therefore, a 50-l gas
bottle permits approx. 5000 welding seals.
A high-frequent ignition current ignites the electric arc via an initiating electrode.
The latter is made of tungsten. Each electrode is identified by a colour on the head and
can therefore be ordered according to DIN by each merchant. The electrode used in
the VS 32-L is of the type WS 2 turquoise with the dimensions Ø 2,4 x 175 mm.
The consumption of the electrode must be compensated for.
Note! Preventive maintenance
Replace electrode before the beginning of shift or after 1000
welding operations at the latest or sharpen it.
The electrode can be ground up to 100 times. Up to approx. 1000 welding spots can be
affected for application between the grinding operations.
The electrode should be provided with 2 grinding angles. An obtuse tip of approx. 70°
and a slim tip of approx. 15 °. Angles being too obtuse provide good ignitability, but it is
their disadvantage that they are consumed too quickly which in turn increases ignition
distance. Sharpening the ignition needle should be done by means of a TITAN-Sharp
grinder.
TITAN holds patents for the TIG welding system in strapping machines Europe and
North America.
The TIG welding method permits the welding of all bright or blued surfaces. In this
context it is important that the surface is not polluted strongly.
Note! Painted strapping material
Galvanised or zinc dust painted strap cannot (!) be welded. The
same applies to zinc portions in paints used.

8.2. Setting the zero position
The zero position of the welding station is set up such that the feather key (26) of the
driving shaft (23) is parallel to the partial axis of the bearing shell. The contact surface
of the switch ring (55) is assigned to switch B3 (195). The thread pin (53) of switch ring
2 (52) is also parallel to the partial axis.
8.3. Setting the clamping and opening positions
If the thread pin (53) of the triple switch ring (52) is also found on the partial axis, the
subsequent clamping and opening positions are correct as well.
The toothed wheel (18) of the opening curve must be plugged such that the cam roller
(32) fits closely to the radius of the opening curve (14). The curve flank is then vertical
to the partial axis. Positions 1 to 3 are engraved on the toothed wheel (29) and can be
controlled there.

8.4. Setting the air pressure
The optimum result is obtained by three pressure settings.
Settings must be affected on the following pressure controllers:
DR 1 Pressure controller on the machine
(Main controller)
DR 2 Pressure controller on the
multi-functional block
DR 3 Pressure controller on the multi-
functional block
1. The pressure controller DR 1 is found on the maintenance unit of the machine.
The maintenance unit provides for the quality of the compressed air. It filters water, oil
aerosols as well as dirt and rust particles from the air and provides the entire machine
with sufficient air pressure. It should be able to discharge oiled and unoiled air.
In case of high level differences between
the maintenance unit and the strapping
head or a hose being longer than 5 m a
separate oiler (700) has to be installed
near the head.
If the machine is without air supply, the maintenance unit-depending on the installation
position of the head must be attached directly to the head or immediately near it
Port cross section: min. 3/4“
Air pressure: 6 bar flow pressure
DR 1 can be set at an impact pressure of 6,0 to 7,0 bar.
Effects of that setting on the strapping head:
The pressure preset results in
Max. strap tension,
the fastest strap feed speed
Selection via speed valve Y2 in the multi-functional block and related consumer valve
Y3, Y4 to Y6.
This setting makes for the speed of the sealing process (Welding station).
VS-32-L 31
Page 32
B 13 GB 33/06
2. The pressure controller DR 2 is found on the multi-functional block. It is set to a
jamming pressure of 1,5 - 2 bar, readable at its manometer.
The pressure preset results in the minimum strap tension, feed and sealing speeds.
Selection directly via consumer valves, Y3, Y4 to Y6.
Main functions:
Precise movement pulse counting
Slow partial feed of strap
Slow return of strap during movement of head “Head on packing item“ B8
3. The pressure controller DR 3 is found on the multi-functional block. It is used to
set all speeds and strap tensions between minimum and maximum.
Selection via speed valve Y1 on the multi-functional block and the relevant consumer
valve Y6.
The main function is the setting of the strap tension.
Pressure is set at the pressure control valve with valve Y1 being activated and read on
its pressure gauge. The blow-off noise of the secondary ventilation can be heard on the
small pressure control valve DR 2, as long as Y1 is selected. This is no problem.
The speed valve Y1 can be activated in manual mode (emergency actuation) or
switched on via the control system.
Note!
Check the flow pressure at the tapping point. Flow pressure
exceeding 6 bar results in increased wear at the compressed air
motors. Pressure being too low results in reduced output.

B 13 GB 26/06
8.5. Setting the quantity of gas
The SV-32-L strapping head comprises a plant for central gas supply, which in turn
comprises a pressure control station and a pressure reducer incl. flow rate meter.
The pressure control station including accessories can be obtained in two designs. The
operation of the head can be designed by means of a gas cylinder or a group of two
with a maximum feed pressure of 200 or 300 bar.
The closed circuit pressure (working pressure) has been controlled by the manufacturer
to 5 bar on the main pressure reducer. That pressure cannot be controlled on the
pressure reducer. In case of decreasing cylinder pressure the working pressure and
therefore the shield gas consumption remain constant.
The quantity of gas required for a welding operation should amount to 10 litres per
minute. It is set on the flow rate meter via the second pressure reducing valve (fig. 4).
That pressure reducer including flow rate meter should be mounted near the head of
the machine.
If the quantity of shield gas is too low (quantity of gas < 10 l/min), the weld metal bead
may be affected by pores.
Set the quantity of gas via the setscrew
of the pressure reducer.
Important:
For safety regulations, mounting
instructions and commissioning of the
central gas feed system see operating
instructions (Fa. Everwand & Fell
GmbH) attached.
All plant sectors must be kept free of oil and grease!
All mounting works deviating from the mounting instructions may
only be performed by an authorised specialised company or the
manufacturer. Otherwise, any manufacturer’s guarantee as well as
all claims within the scope of the product liability act will expire.
Caution!
Gas bottles are to be protected against dangerous heating up (over
50°C) by heating elements or open flames. Bottles at a wellventilated place store and against falling down secure.

1. Manually unscrew the gas nozzle (668).
2. Detach the tensioning sleeve casing (666) by
means of torch wrench (560).
3. Insertion of the igniting electrode (669) into the
tensioning sleeve casing. The electrode should
project approx. 30 mm. Manually screw in casing.
4. Use the torch wrench preset to slip the electrode
into the casing to size and screw it.
5. Manually screw the gas nozzle firmly.

Note!
If the clamping sleeve housing, the clamping sleeve or the welding
electrode will be exchanged separately, the adjusting of the burner
has to be controlled. Due to the modified constellation it is possible
that the distance between welding electrode and support of the
burner change.

9. Maintenance
9.1. General
Regular and careful maintenance provides for the permanent readiness for operation of
the strapping head of the type VS-32-L. The strapping head must always be kept clean.
Always keep strap guidance's and sealing sector free of pollution and foreign
substances.
The kind of packing material and its surroundings are decisive for
the cleaning intervals. Main attention has to be paid for abrasive
material originating from work with steel strap; that may result in
malfunctions.
For cleaning only use environmentally friendly cleaning agents
which neither damage plastic materials nor the painting on the
machine.
All parts must be checked at regular intervals and replaced when
worn out. Parts worn out affect the sealing strength and have
influence on the transport security of the packing item.
Attention!
Disregarding that note may result in faults and injuries.
Only use original TITAN spare parts!
The use of spare parts not manufactured by TITAN excludes
guarantee and liability.
Caution!
In case of maintenance works on live parts of the strapping head
the main switch of the control system must be set to position “0“
and secured.
Tool inspection!
Perform a daily visual inspection of the outside of the unit. The early detection of
damaged parts extends the life of the unit. Replace all damaged parts immediately
with Original TITAN spare parts.

4) Sliding at clamp 2, cutting edge of upper strap is not positioned
at the cutting mark, therefore loose strapping.
VS-32-L 38
Page 39
B 13 GB 26/06
9.4. Lubricating points
All bearings installed are provided with a long-term lubrication which requires
republication once or twice a year. All sliding surfaces of the welding station require
lubrication. The gear unit, the ball and needle bearings of the compressed air motors
must be lubricated with grease on the lubricating nipples every six months.
The following greases can be used:
Shell Retinax AM
Mobilgrease Special
DEA Molytex Grease EP 2
Esso Multipurpose fat
Aral Multipurpose fat F
Molykote BR2 Plus extends the lubrication intervals.
Important!
This head may only be used in connection with a compressed air maintenance unit
comprising a pressure reducer, water separator and oiler. It cleans the compressed air,
removes condensation water and permanently supplies the motors with the quantities
of oil required. On its upper side the oiler is set by means of screwdrivers such that
each strapping operation makes a drip of oil drop in the inspection glass. Cw turning
causes more oil, ccw turning less.
Attention!
In no case the strapping head may be operated without oil in the
oiler, since that would immediately result in the destruction of the
compressed air motors.
During the entire operation the compressed air motors must be operated with filtered
and oiled compressed air. As to quantity per 1 m³ air approx. 3 to 5 drips are required,
this corresponds to 0,12-0,2 g/m³. Primarily, lubricating oil should be unalloyed mineral
oil. It must be fluid and free of resin and acid.
A viscosity of 2-4 °E at 50°C (12-30cSt) has been found successful (for further
temperature ranges see viscosity table). Motor temperatures of -30 to +100 °C are
admissible. However, in case of ambient temperatures of below +5 °C there is the risk
of icing. In that case dried air or icing-inhibiting lubricants (e.g. "Killfrost Anti Eis") are
recommended.
Caution!
Wear breathing mask when using antifreeze agents.

9.5. Maintenance of the transport unit
The maintenance and inspection of the transport (392) and tensioning (3401) wheels
should be performed every week. After the disassembly the tooting must be freed of
wax and paint residues by means of a wire brush.
Worn-out wheels require replacement.
The counter rollers (352) and (420) and the strap guidance’s (4261) and (4251) should
be checked once a month and free of paint, dirt and wax residues.
Dismounting and mounting
The following tool is required for mounting and dismounting operations:
hexagon socket screw key SW 5, 6 and 8 mm, slotted screw driver.
Unscrewing the protecting ledges (1042/1172) and the flap backside (5691).
Loosening the fastening screw (372) of the retention pin (522) and removal at the
pin heel. Swinging out the counter bearing elements (3481/3491), simultaneously
lifting the tensioning motor (430). The counter roller (352) and the strap guidance
have canned then are cleaned (fig. 5 to 8).
When loosening the 2 fastening screws of the rocker cover (334) the latter can be
removed by means of its handle (400) and the tensioning wheel (3401) found
below can be dismounted. The tensioning wheel is linked to the driving shaft via a
feather key and can be removed towards the front (figs. 9 to 10).
The transport wheel (392) is secured by means of a safety disk (394). It can be
loosened by means of a screwdriver or pincers, and the transport wheel can be
removed towards the front. The counter roller (420) found below and the
guidance’s (4251/4261) can then be cleaned (fig. 11).
Mounting is performed in the reverse order.
Slightly lubricate all parts (exc. screws).

9.6. Maintenance of the clamp guide
During checks and maintenance of the clamp guide special attention must be paid to
the clamping and cutting edges of the cutting plate. They should have sharp edges or
have a slight radius of max. 05 mm. Strongly rounded edges cause the slipping of the
strap during the tensioning operation or a strong formation of burr during cutting.
Check die (1671), side jaws (1691 / 1701), guide (1711) and flaps (1731 / 1741) for
wear and replace elements, if required. Further, paint, wax and dirt residues on the
strap guidance positioned inside must be removed.
When strapping material is welded, residues of burnt wax and paint particles which
might impair the readiness of ignition of the electrode are formed on the base plate.
Those residues must be removed from the base plate by means of a wire brush
regularly (once a month) (fig. 16).
Dismounting and mounting
The following tool is required for dismounting and mounting operations:
Hexagon socket screw keys SW 5 and 8 mm.
Loosening of the upper 2 fastening screws (184/186) of the protecting ledges
(1042/1172); slip the protecting ledges aside. Relieve the pressure springs (158)
by loosening the threaded pins (159) (fig. 12).
Loosening the sealing screw (166) and extraction of the lock (562). Loosening the
supporting strip (4) and base plate (1) (figures 13 to 14).
Then the clamp guide can be removed from the sealing unit (fig. 15). If required,
the cutting plate acc. to section 9.7 can be dismounted.
Mounting is performed in the reverse order.

9.7. Maintenance of the cutter
The cutting edge of the cutter must be checked regularly in the same way as it is done
with the clamping or stationary cutter edges. If that edge is notch or broken, it must be
replaced.
Attention!
Broken cutter edges may cause faults in strap feed and return
motions. The beginning of the strap is bent!
Dismounting and mounting operations
The following tools are required for dismounting and mounting operations:
Spring hooks, hexagon socket screw keys SW 6.
To dismount the cuter relieve the pressure springs (116) by means of spring
hooks (fig. 17).
The sealing unit can now be tilted open and the cutter guidance can be removed
from the clamp guide by the loosening of the cheese-head screw (fig. 18).
Mounting is performed in the reverse order.
