APPLICATION

WELDPLAST S4

WELDPLAST EC4

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
reach combustible materials, which are out of sight.

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.

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!

Working environment / safety

In the case of interruptions to welding
work, the drive motor can be swit­ched off with the motor on/off switch
(2). Place the hand extruder with the
handle appropriately positioned and
tightened on a stable fireproof sur­face as illustrated.

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.

Adjusting the handle

The clamp is loosened by turning the plastic handle
counter-clockwise and the handle can be positio­ned in the ideal working position by sliding back or
forwards. The handle can also be rotated for
left/right handed users (see also Welding direction
left/right)

Workstation

For starting operation of the hand extruder and setting
it down, Leister offers a comfortable universal tool
stand with integrated hot-air hood and welding rod
dereeler holder (see Accessories).

Power supply

When using an extension cable, take care to ensure the minimal cable cross­section:

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.

The tool starts immediately by heating up to the target temperatures last set. A
counter in the status display then counts down the warm-up lock time of 220 sec. The
hand extruder reaches its operating temperature (READY* status) after approx. 8
minutes. On completion of the starting procedure the tool is ready to weld.
