Application

Please read operating instructions carefully before

use and keep for further reference.

Operating instructions

Danger to life!

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

Operating

Working environment / safety

When interrupting the welding, the drive is to be

switched off with the drive on/off switch (2).

With the handle properly adjusted and firmly tightened,

place down the manual extruder on a stable and

fire-proof surface as shown in the figure.

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

For starting operation of and placing down the hand

extruder, Leister offers a universal device stand.

Operating

Power supply

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

Extension cables must be approved for the working environment (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.

After switching on the main switch (1), the device directly heats up to the last adjusted set

values. When the set values are reached, a counter in the status indication counts back from

220 seconds to zero. Once this starting procedure has elapsed, the device is ready for welding

(status: Ready*). The operating temperature of the manual extruder is reached after approx.

5 minutes.

After a short-term mains break, the starting procedure is not repeated.

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 (30 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 “30” and the potentiometer is set to “minimum”, the next smallest

welding rod thickness must be selected.

Operating

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).

Example

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 set and actual values of the AIR and PLAST tempe-

ratures are continuously monitored. If the actual value

deviates from the respective set value (value outside the

tolerance band), this is indicated on the status display

(30) with a status change. If necessary, the drive motor is

temporarily disabled until the welding parameters are

once again within the prescribed tolerance band. The

possible status displays and the tolerance bands may be

seen in the following graph 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).

WELDPLAST S2 PVC

• PVC-U may only be processed in the PVC-U menu.

• WARNING: Use only PVC-U, not PVC-C.

• To prevent corrosion, if the machine is not going to be used for a longer period of time

(more than 2 days) it is recommended to fill it with HD-PE.

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 Stand-by/Enter button (26).

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

• Switch off the main switch (1).

Operating

CAUTION!

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

Always operate the device with welding rod.
