1. Type
Art.-no/Type of machine : DX318 ExOn8 3x400V
Machine no. : .........
Required voltage : 400 V / 50 –60 Hz
Heating unit for extruder : 1200 W
Heating unit for air : 3300 W

2. Safety
Pursuant to sec. 55 of VDE 0 100 (Regulations of the Association of German
Electrotechnical Engineers), the extruder must be operated using a protective switch or an
isolation transformer.
Keep extruder dry.
Operating hand-held welding and extruding machines is subject to applicable national
regulations. Observe applicable regulations for the prevention of accidents as well as
technical rules for safe and professional operation.
Directive 92 / 57 / EWG dated June 24, 1992, shall be applicable by analogy.
Utilisation:
Hand-held welding and extruding machines are manufactured according to the latest state of
the art and in compliance with safety requirements.
Any improper use may result in dangers for the operator or third parties or may adversely
affect machines and assets.
Only use hand-held welding and extruding machines if in technically perfect condition and for
the purposes for which they are intended while observing the operating instructions.
The manufacturer / supplier will not accept any liability for any failure to comply with the
above or for damages resulting therefrom.
Any utilisation of the hand-held welding and extruding machine for other purposes than those
for which it is intended is subject to the consent of the manufacturer / supplier.
Work on electrical parts of the hand-held welding and extruding machines may only be
performed by an electrical engineer in compliance with electro-technical rules.
Special risks:
All hand-held welding and extruding machines may only be held and operated using the
handles provided for this purpose.
A risk of burning exists on all uncovered metal parts. Avoid contact with these parts
because they may achieve temperatures of up to 350 °C.

Safety area:
The hot air stream of the hand-held welding and extruding machine may not be directed to
temperature-sensitive objects or living things. Ensure that a safety distance of 2 m is
observed in all directions.
Operation:
Never use hand-held welding and extruding machines without air supply. In case of external
air supply ensure that the feed line is of sufficient size.
The pressurised air that is supplied must be free of oil and water.
Safety:
Check for correct nominal voltage before connecting the hand-held welding and extruding
machine to the mains voltage.
Mains voltage must be identical to the nominal voltage shown on the type plate of the hand-
held welding and extruding machine.
Pursuant to sec. 55 of VDE 0 100 the hand-held welding and extruding machine must be
operated using a protective switch or an isolation transformer.
Extension cords:
When using extension cords the minimum diameter of cables must be observed.
Length up to 18 m: diameter 2.5 mm²
Length up to 50 m: diameter 4.0 mm²
Extension cords must be approved and marked for their place of utilisation.
Stop operating the hand-held welding and extruding machine if:
- connecting line or plug have been damaged
- safety installations have been damaged
- foreign objects or liquids have entered the hand-held welding and extruding machine
-changes occur in the operating state
Never spray water on hand-held welding and extruding machines
(risk of short circuit)
Never use hand-held welding and extruding machines in hazardous or inflammable areas.

3. Start-up
General:
Observe the notes on safety contained in these operating instructions. In addition, the
regulations on the prevention of accidents and the national regulations shall apply.
Assembling the hand-held welding and extruding machine
When dispatched, our hand-held welding and extruding machines are almost completely
assembled.
What remains to be done is to screw the enclosed handle to the machine.
For machines with external air supply the air supply hose must be connected.
Ensure sufficient supply with air which is free of oil and water (min. 300 l/min).
We recommend our air compressor, item no. DX 011.
Connect extruder with control box.
Weld shoe
The machine is supplied with two weld shoes blank which can be machined to suit your
requirements.
Note: please observe guideline DVS 2207 part 4.
If you indicate your required form of seam and thickness of plates we will supply two weld
shoes machined ready for use.
Start-up of hand-held welding and extruding machine
Observe the section concerning safety of these operating instructions.
Hand-held welding and extruding machines may not be used without air supply. This would
inevitably result in damages of the extruder.
Before connecting the extruder to the mains supply please check that
- the On/Off switch of the heating unit is in OFF position
- air supply is connected correctly
- the driving machine has not been put to permanent operation
- now switch on air supply
-and put plug into socket.
All our hand-held welding and extruding machines are provided with patented mass
measurement (the thermoelement is installed directly in the melting unit, between
worm and die) and with cold start protection.
Now put the On/Off switch of the heating unit into ON position. The machine will heat up to
the last selected temperature value. For information on how to modify the desired
temperature value please refer to the section on the adjustment of the controlling unit.

Controller –desired value setting
All controllers can be changed only in the desired value and are electrnically locked against
wrong inputs.
Change the desired value
The controller indicates actual and desired value temperature at the same time. To change
the desired value temperature proceed as follows:

on the desired value display. If this
key is kept constantly pressed, then
the value is sequentially becomes

Changing the welding filler
Heat up the hand-held welding and extruding machine until operating temperature is reached
to ensure that no welding filler is present in the machine, remove the weld shoe and
exchange the die (caution, left-handed thread) by a new one or by a die used with the
material to be applied now.
Caution: Risk of burning when working on the heated machine
After removing the old die and before placing the new one run the machine for approx. 1 min.
on new Welding filler.
Interruption of welding operations
Never leave the hand-held welding and extruding machine unattended.
Air supply may not be broken.
Caution: When processing PVC or PVDF, hand-held welding and extruding machines may
not be stopped for more than 3 min.
In such a case or if welding operations are completed a cleaning run must be performed on
the machine for about 2 min. using PE or PP welding filler.
Switching-off the hand-held welding and extruding machine
Place hand-held welding and extruding machine onto the support stand included in the
scope of supply.
Put the On/Off switch into OFF position and pull the plug after about 2 min.
Caution: Even after 15 minutes there is still a risk of burning present on uncovered
metal parts.
Never use water or other substances to speed up the cooling process.
Maintenance
Always disconnect the machine from power supply before performing any maintenance work.
Maintenance work may only be performed by skilled electricians.
Observe section on safety contained in these operating instructions!
Inspection
After an operating time of about 500 hours the hand-held welding and extruding machine and
the drive unit must be cleaned, re-filled with new grease and tested.
This work may only be performed by skilled electricians.
Drive unit
Check carbon brushes of the drive unit approximately every 100 operating hours and replace
them, if necessary.
Thrust bearing / extrusion worm
It is recommended to clean thrust bearing and extrusion worm and to re-grease the bearing
approximately every 200 operating hours.
