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.

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.

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.

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.
