2. General
Thank you very much for your confidence in the technology of TITAN
Umreifungstechnik GmbH & Co. KG!
These operating and maintenance instructions are meant to facilitate how to become
acquainted with the strapping machine and apply it as intended. The operating instructions
comprise important information on how the strapping machine can be used safely, as
intended und economically.
The operating instructions must permanently be available at the place the strapping head is
used. They must be read and applied by all staff members working with the strapping head.
Such works especially include operation, troubleshooting and maintenance.
Adjustment and maintenance works may only be performed
by trained technical staff.
Notes on the warning and information symbols:
Caution!
Is used in case of risks threatening life and health.
Attention!
Is used in case of risks which may cause damage to objects.
Note!
Is used for general notes and such notes whose disregard may result
in faults in the course of operations.
The item numbers (…) and designations used in these operating instructions refer to the
spare parts list or documentation on the electrical system.

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.
B 13 GB 33/06

VS-32-L 6
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.

3. Safety regulation
Read the operating and maintenance instructions before the use of
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!
B 13 GB 07/10

VS-32-L 8
Before the beginning of cleaning works and / or troubleshooting the
strapping head must be put out of operation. Main switch at
position OFF.
Attention! Strap may tear! Do not stand in the alignment of the
strap.
Wear eye and face and hand protection when eliminating fault
strappings
When cutting the strap hold the upper parts firmly
(see figure).
Attention! The lower part of the strap jumps upward.
Consider the strong development of noise during longer
operations. Therefore, protect your health.
Exclusively use original TITAN spare parts! The use of spare
parts not made by TITAN excludes guarantee adjustments and
liability.
In automatic mode attention has to be paid that no squeezing
points may occur between the feeding installations (e.g. roller
conveyors) and the movable strapping unit.
We do not accept liability for alterations to the strapping
machine! Further, warranty/guarantee and these operating
instructions become inapplicable.

the TIG Inverter shield gas
welding unit see operating

4. Life phases of the unit
Transport:
Attention! Do not stay beneath the load during lifting and
depositing. Order individuals standing in the hazardous area to
leave it. Minimum carrying capacity see technical data on page 11.
Putting the unit in operation:
The strapping machine may be put in operation by trained
technical staff only.
Setting, programming:
Setting and programming works related to the strapping unit may
only be performed by trained technical staff.
Operation, modes:
Manual mode:
Manual mode permits the implementation of individual works performed for testing and
troubleshooting. Further, manual mode is applied to take the strapping unit to home position.
Attention! During the touch control of the cam gear there is a risk
of squeezing at the strap guides and the counter plate.
Automatic mode:
Automatic processing of all movements.
In automatic mode attention must be paid that no points with the
risk of squeezing may occur between the feed installations (e.g.
roller conveyors) and the movable strapping unit.
B 13 GB 07/10

VS-32-L 10
Cleaning, maintenance, repairs:
Just trained technical staff is allowed to perform maintenance and
repair works on the strapping unit.
Attention! Before beginning with any maintenance work the
relevant staff must disconnect the strapping unit from the power
mains.
Attention! Wear protective glasses when cleaning the unit /
machine with compressed air.
Putting the unit out of operation, disassembly
Attention! When dismounting the strapping machine there is the
risk of squeezing.
Attention! Do not stay beneath the load during lifting and
depositing. Order individuals standing in the hazardous area to
leave it. Minimum carrying capacity see technical data on page 11.
Waste disposal
If packing material is to be disposed of, take it to the relevant
recycling container or admit it to the Dual System.
Should the strapping machine have to be disposed of at the end of its service life, separate
plastic material, steel and aluminium and dispose of such materials separately. In the same
way, motors and electric modules like control system, switches and cables must be admitted
to separate waste disposal. Take such elements to the appropriate waste management.
