Leister WELDPLAST S6

Hand extruder

Hand extruder for welding thermoplastics from PE and PP filler rod with a diameter of 4 and

5mm (other materials on enquiry) in the construction of containers, apparatus, pipelines

and storage sites.

Electroconductive material (e.g. PE-EL) may not be welded.

Application

Please read operating instructions carefully before

use and keep for further reference.

Operating instructions

(Translation of the original operating instructions)

Danger to life! Danger to life when opening up the tool, as live com-

ponents and connections are exposed. Before opening the tool,

unplug from the mains supply. Electrically conducting material (e.g.

PE-EL) must not be welded.

Fire and explosion hazard with incorrect use of the hand extruder

(e.g. overheating of the material), especially near combustible

materials and explosive gases.

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 to be connected to a RCCB (Residual Current Circuit

Breaker).

The voltage rating stated on the name plate of the tool must

correspond to the mains voltage.

In case of a power outage, the main switch and the drive must be

switched off (loosen lock).

Danger of getting burned! Do not touch exposed metal parts

and escaping plastizised material. Do not point the hot air flow

and escaping plastizised material in the direction of people or

animals.

Protect tool from dampness and wet.

Warning

Caution

Connect the tool to a mains socket with protective earth.

Every interruption of the protective earth inside or outside of the

tool is dangerous!

Only use extension cables with protective earth conductor.

Operating Leister WELDPLAST S6 hand extruder

Working environment / safety

The hand extruder must not be used in inflammable environments or where

explosion hazards exist. Ensure stable positioning during operation. The

connection cable and the welding rod must remain unimpeded and must not

hinder the user or others during operation.

Rest the hand extruder on a fireproof surface! Hot metal parts and the hot-air jet

must have sufficient clearance from the surface and walls.

Handle Adjustment

1. Loosen the clamping by turning the handle (6) in

counterclockwise direction.

2. Adjust handle (6) to the requested working position.

3. Tighten handle clamping again by turning handle (6) in

clockwise direction.

Workplace

When not welding, the drive should

be switched off with the drive on/off

switch (2).

Place the hand extruder on a stable,

fire resistant base, as shown in the

illustration.

Operating Leister WELDPLAST S6 hand extruder

Power supply

If an extension cable is used, it should have a cross section of at least 3 × 4mm2and

must be permitted for the place where it is being used (e.g. outside) and labelled

accordingly.

When using a power set for power supply, the nominal power rating for the power

set is: 2 × the nominal power rating of the hand extruder.

After switching on with the main switch (1), press any key on the operating unit (32).

The device then heats up to the last ideal temperature set. When the ideal temperature

is reached, a counter on the status display counts back from 310 seconds to zero. After

this start-up process is complete, the device is ready to weld (status Ready*). The hand

extruder takes around 8 minutes to reach its temperature range. If the power is only

turned off for a short time, the start-up process does not need to be repeated.

main switch (1), the device name and the

current software version are shown in the

Software and menu guide

The Weldplast manual welding extruder is fitted with convenient software, which makes wor-

king with the extruder easy for the user.

Adjusting the Output Capacity

Due to the seam form, the output capacity and the pre-heating period can be matched to

each other.

• Pre-adjustment at the display

– By pressing the select key (28), set the cursor to the «SPEED» position.

– Specify the maximum output value (60 to 100) via the up key (29) or down key (27)

(indication via the bar display for drive (22).

• Fine-adjustment during the welding procedure

– By turning the potentiometer (3), the output capacity of the maximal set output value

(e.g. 85) can be reduced to the minimum.

The output capacity depends on the thickness of the welding wire. If the welding output is too

high with the output display «60» and the potentiometer is set to «minimum», the next smallest

welding rod thickness must be selected.

Setting parameters in the operating window

The cursor (31) shows which parameters can be set. After switching on, the cursor is on

the «SPEED» position.

In the operating window, the following parameters can be selected with the Select key (28)

and changed in their values with the Up key (29) and Down key (27).

Set value Set value Set value

Setting the PLAST and AIR temperatures

• Set the cursor to the «PLAST» or «AIR» position by pressing the Select key (28).

• Set the temperature value with the Up (29) or Down (27) keys.

Monitoring the welding parameters

The actual and ideal values of the AIR and PLAST temperatures

are constantly monitored. If an actual value deviates from the

relevant ideal value (value is outside the range of tolerance), this

will be indicated by a change in status on the status display of

the drive (30). If necessary, the drive motor will be temporari-

ly disabled. When the actual and ideal values of the AIR and

PLAST temperatures are within the range of tolerance again, the

message «Press any key» will appear on the status display of

the drive (30). Any key on the operating unit (32) must be pres-

sed to release the drive motor again (preventing the device from

being started up accidentally). The possible status display and

the ranges of tolerance are shown in the following graphic and

table.

Starting the welding process

• Fit the appropriate welding shoe (8) as required.

• Set the potentiometer (3) to max.

• Once the operating temperature is reached («READY*» status), welding can begin.

• Actuate the drive on/off switch (2).

• Insert a 3 or 4 mm welding rod into the welding-rod intake (12).

• The welding rod is automatically drawn in through the welding-rod intake (12). The

welding rod feed must take place without resistance.

• Interrupt drive by releasing the drive on/off switch (2).

• Direct the pre-heating nozzle (9) towards the welding zone.

• Pre-heat the welding zone with a fanning motion.

• Apply the device to the prepared welding location and actuate the drive on/off switch (2)

again.

•

Perform test welding by following the welding instructions from the material

manufacturers and national standards or directives.

• Inspect test welding.

• Adjust the temperature setting and welding output as required.

• For long welding jobs, the drive on/off switch (2) can be locked-on with the drive

locking device (4).

Switching off the tool

• Disengage the drive locking device (4) and release the drive on/off switch (2).

Remove the welding material in the welding shoe so that the welding shoe will not

be damaged when starting the next welding run.

• Switch off the heating systems with the Enter key (26).

• Allow the device to cool down for approx 5 minutes.

• Switch off the main switch (1).

CAUTION!

Never insert welding rods into both welding-rod intakes at the same time.

Always operate the device with welding rod.
