DANGER!

Danger when opening up the tool, as live components and connections are

exposed. Therefore, before opening it, unplug the tool to ensure disconnection

from the mains. Electronically conductive material (eg PE-EL) must not be welded.

Incorrect use of the hand extruder (eg 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. Do not direct stream of hot air or

emerging material towards people or animals.

Warning

The tool 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 tool be

connected to a RCCB (Residual Current Circuit Breaker) .

Protect tool from damp and wet.

Caution

Application

Welding PE and PP thermoplastics for applications in

• container engineering • pipeline construction

• plastic fabrication • landﬁll sites and abandoned polluted areas

The voltage rating stated on the tool must correspond to the mains voltage.

If power failure occurs, the hot air blower switch and drive must be switched o

(release locking device).

• The tool rest (8) or handle (9) can alternatively be mounted left of right of the tool.

• Before putting into operation, check power supply cord (13) and connector as well as extension cable for

electrical and mechanical damages.

• When using an extension cable, take care to ensure the minimum cable cross-section:

•Extension cables must be approved for the place of work (e.g. outdoors) and labelled accordingly.

• If a generator is used to supply electricity, the rated power of the generator must be 2x the rated power of the

hand extruder.

The hand extruder must not be operated in inﬂammable environments or where explosion ha-

zards exist. Ensure stable positioning during operation. The connecting cable and the welding

rod must remain unimpeded and must not hinder the user or others during operation.

Starting protection

The tool is equipped with current overload protection. The drive switches o automatically if current consumption

is too high. The drive can for example not be started, or only for a brief time, if the material in the screw

is insufficiently plastizised.

Overheating protection

If the drive overheats as a result of external inﬂuences or if the melting temperature of the material in the screw

is too low, the internal temperature protection switches o the drive. The overheating protection switches on

again automatically once the drive has cooled down.

• Connect the hand extruder to the mains supply.

• Switch on the tool at the hot air blower switch (1).

• Adjust the hot air temperature at the air temperature potentiometer (2).

• The operating temperature is reached after approximately 10 minutes

Starting the welding process

• Fit the required welding shoe (5) according to the paragraph „Change of welding shoe” (see page 15).

• Welding can begin once the operating temperature has been attained. Operate the drive on/o switch (4) for

this purpose. Operate the tool only when feeding welding rod.

• Feed welding rod into the welding rod opening (6) (see chapter welding rod) and allow a small amount plasti-

zised material to escape.

CAUTION! Never feed welding rod into both welding rod openings at the same time! (see page

13 «Starting protection»).

The welding rod fed must therefore be clean and dry.

• The extrusion rate can be changed using the extrusion rate regulation potentiometer (7) dependent on the

seam geometry and the choice of material.

• Interrupt material extrusion using the drive on/o switch (4).

• Direct the pre-heating nozzle (21) to the welding zone.

• Pre-warm the welding zone with back and forth movements.

• Position the tool on the prepared welding zone and operate

the drive on/o switch (4).

• Carry out test welding and analyse.

• Adjust the hot air temperature using the air temperature potentiometer (2) and the extrusion rate with the

extrusion rate regulation potentiometer (7) as required.

• In case of a prolonged welding process, the drive on/o switch (4) can be held in the active state with the

locking device (3).

• The welding rod is pulled in through the welding rod opening (6) automatically after starting. The welding rod

pull - in must not be impeded.

• Release the locking device (3) by brieﬂy pressing the drive on/o

switch (4) and then letting go. Remove welding material from the

welding shoe in order to avoid damage on the welding shoe when

starting the next time.

•

The tool must only be laid down on the tool rest (8)

Use a ﬁreproof base. The hot air jet must not be directed towards

persons and objects.

•The air temperature potentiometer (2) to „0“. Let the tool cool down.

•Switch o at the hot air blower switch (1).

Checking the temperature of the extruded material and the pre-heating temperature

• The temperatures of the extruded material and the hot air jet are to be checked at regular intervals when car-

rying out welding work over an extended period:

Fast display electronic temperature measuring devices with the appropriate temperature probes have to

be used. The highest temperature in the hot air jet between the nozzle outlet plane and a depth of 5 mm

is to be determined. The measurement probe must be inserted in the welding shoe in the middle of the

extruded material to measure its temperature.

Danger of getting burned! Work with temperature resistant gloves only.

•The welding shoe must only be changed when the tool has attained its operating temperature.

Changing the welding shoe

• Disassembly

– Remove the welding shoe (5) with the welding shoe holder (17) by unfastening the clamp screws (18)

from the extruder nozzle (19).

– Every time the welding shoe is changed, clean the extruder nozzle (19) of welding residue and make sure

that it is screwed in tightly.

– Remove welding shoe (5) from the welding shoe holder (17) by unfastening the fastening screws (20).

• Assembly

– Fasten a welding shoe (5), appropriate to the welding seam, onto the welding shoe holder (17) with

fastening screws (20).

– The welding shoe (5) and welding shoe holder (17) must be tightened properly with the clamp screws (18)

• The welding shoe (5) can be turned infinitely to

the desired welding direction by loosening the

clamp screws (18).

• The clamp screws (18) must be tightened well

again afterwards.

Switch o the hot tool and disconnect it from the mains supply.

Accessoires

• Only Leister accessories must be used.

Maintenance

•In case of soiling clean the air inlet (15) on the hot air blower with a brush.

•

Clean the extruder nozzle (19) each time the welding shoe is replaced and remove any welding deposits (see page 15).

• Check power supply cord and plug for electrical and mechanical damage.

•Regularly clean the air hose (16).

Service and Repairs

• Have the state of the carbon brushes of the drive and hot air blower checked by your service centre after

ca. 250 hours of operation. The drive and the hot air blower switch off automatically once the minimum

carbon length has been reached.

Operating time; Drive ca. 300 hours (brushes)

Hot air blowers ca. 1000 hours (brushes)

• Repairs should only be carried out by authorized Leister Service Centres. They guarantee a specialised and

reliable Repair Service within 24 hours using original spare parts in accordance with the circuit diagram and

spare parts list.
