DANGER!
Danger when opening up the device, as components and connections are ex-
posed. Therefore, before opening it, unplug the device to ensure disconnection
from the mains.
Danger of fire and explosion! Incorrect use of the automatic welder (e.g.
overheating of the
material) can present a fire and explosion hazard, especially near
combustible materials and explosive gases.
Danger – can cause burns! Do not touch bare metal parts and emerging
material while hot. Allow the device to cool down.
Warning
The device must be operated under supervision. Heat can ignite flammable
materials which are not in view. The machine may only be used by qualified
specialists or under their supervision. Children are not authorized to use
this machine.
For personal protection on building sites we strongly recommend the device be
connected to a RCCB (Residual Current Circuit Breaker).
Protect device from damp and wet.
FI
Caution
The voltage rating stated on the device must correspond to the mains voltage.
In case of a power loss, the potentiometer drive speed (12) and potentiometer
heating (15) had to be set to 0.

Only connect the tool to a receptacle with protective earth conductor. Any dis-
connection of the protective earth conductor, in or outside the tool is dangerous!
Use line/mains extension cables with protective earth/ground conductor
and adequate cross sectional area only!
While working on the open system avoid wearing garments such as shawls,
scarves and ties. Long hair must be tied or protected by headgear.
Moving parts may not be touched. The danger exists of inadvertently becoming
caught and being pulled in.

ining bags, etc.
Note: For welding materials made of PVC the miniwelder with
a steel wedge must be used.

The miniwelder tex2 is designed for overlap welding of mate-
rials made from textiles and coated textiles and thinner syn-
thetics from 100 microns up made from PE, PP, PVC, EVA.
Any use other than or beyond that described above is deemed
non-intended.
Areas of use:
Production of sealing barriers and covers in agriculture, ponds,
greenhouses, tarpaulins, architecture.
Application miniwelder roof2
Note: For welding materials like thermoplastic sub-roof mem-
branes (PVC and TPO), the miniwelder with a steel wedge must
be used.
Intended use:
The miniwelder roof2 is designed for overlap welding close to
the edge of thin sub-roof membranes made from: PVC, TPO/
FPO, thermoplastic EPDM.
Any use other than or beyond that described above is deemed
non-intended.
Areas of use:
Pitched roofs, slightly sloped roofs, assembling of membranes
for indoor applications.

Adjustments
Fine adjustment Pressure
Turn adjusting screw (23) anticlockwise to reduce the
pressure down to 30 % of the maximum welding pressure.
For thinner or softer materials reduce the pressure.
Pressure roller alignment (Drive rollers)
Loosen screw (19). By turning screws (18) you can adjust
the angle of the upper pressure roller. This adjusts the posi-
tion to the lower pressure roller. Carry out a test weld to
check the position is correct. The weld pressure should be
the same from the left side to the right side. Attention in the
relaxed position the rollers are not parallel. Adjustment is
necessary for HDPE > 0.5 mm. Tighten screw (19) to lock
the position.
Wedge position adjustment
Loosen screws (24). Place 2 pieces of the material to be
welded between the pressure rollers and close the tension
lever (6). Move the wedge with light pressure between the
material towards the pressure rollers. Wedge must be at
right angle to pressure rollers. Tighten screw (24).
Hold down rollers (only for geo2)
Place two pieces of the material to be welded between the
pressure rollers (8) and upper (10) and lower hold down
rollers (25) and close the tension lever (6). By turning
screw (21) position the upper hold down rollers (10). By
turning screw (20) adjust the pressure exerted on the wedge
by the upper and lower hold down rollers (25).
Before adjusting components, pull plug from power supply.

Work environment and safety
Attention: For optimal welding results the material should
have maximum contact to the upper and lower side of the
wedge during the welding process.
Replacing pressure rollers (8)
Depending on welding material choose the right pressu-
re rollers (8) steel or silicone (both in combination also
possible). Unscrew locking screw-pin (26). Replace upper
and/or lower pressure rollers (8) and reinsert locking
screw-pin (26).
Attention:
Square-end of flexible wire (27) must be inserted carefully.
While working on the open system avoid wearing garments such as shawls, scarves and ties.
Long hair must be tied or protected by headgear.
The miniwelder should be used only in the open or in a well-ventilated area.
Never use the miniwelder in explosive or readily inflammable surroundings and maintain su-
cient distance from combustible materials or explosive gases at all times!
Read the material safety data sheet of the manufacturer of the material and follow that compa-
ny’s instructions. Be careful not to burn the material during the welding process.
Use the device only on a horizontal (roof slope up to 30°) and fireproof support.
In addition, comply with national statutory requirements regarding occupational safety (securing
safety of personnel or devices)!
Anti-fall protection when working on areas where there is a danger of falling.
When welding on roof parapets and eaves, a stop fixture with horizontal guides (e.g.
rail or rope safety systems) must be secured to the carrying handle of the miniwelder
as protection against falling.
With respect to the safety chain, care must be taken to ensure that all of the safety elements
(carabiner hooks, ropes) have a minimum load-carrying capacity of 7 kN in every anticipatable
direction. For the suspension of the machine, it is mandatory to use clasp carabiners (Twist-
Lock or screw types). All safety chain connections must be installed and checked correctly in
accordance with manufacturer specifications.

• Insert the power plug, turn on the power by pressing the On/O buttons for heating and drive (14 + 17) and
select temperature and speed, then take two narrow pieces of material for welding trials. Temperature selection
can be dierent for the same material at dierent ambient temperature and material thickness. To determine
the best welding result, adjust the speed to approximately 2 m/min, and then make dierent trial welds while
slowly adjusting the temperature from low to high.
• Evaluate welding parameters by carrying out tensile testing.
• After temperature and speed have been determined, insert material to be welded between the two pressure
rollers, and engage the tension lever to start the welding process.
• Check the welded seam. If required, correct the speed with the potentiometer drive (12).
• When welding is completed, disengage the tension lever to prevent damage to the pressure rollers. Pressure
rollers should never run against each other without material between them.
• Push On/O-button for heating and drive.
• Disconnect the mains voltage plug.
• Allow device to cool-down.
Perform a test welding according to the welding instructions of the material manufacturer and the
national standards or guidelines. Check the test welding.
