1. Type
Art.-no/Type of machine : DX315 ExOn7 3x400V
Machine no. : .........
Required voltage : 400 V / 50 – 60 Hz
Heating unit for extruder : 1200 W
Heating unit for air : 3300 W
Extruder drive unit : 1500 W-400V
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 s itch or an
isolation transformer.
Keep extruder dry.
Operating hand-held elding and extruding machines is subject to applicable national
regulations. Observe applicable regulations for the prevention of accidents as ell as
technical rules for safe and professional operation.
Directive 92 / 57 / EWG dated June 24, 1992, shall be applicable by analogy.
Utilisation:
Hand-held elding and extruding machines are manufactured according to the latest state of
the art and in compliance ith 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 elding and extruding machines if in technically perfect condition and for
the purposes for hich they are intended hile observing the operating instructions.
The manufacturer / supplier ill not accept any liability for any failure to comply ith the
above or for damages resulting therefrom.
Any utilisation of the hand-held elding and extruding machine for other purposes than those
for hich it is intended is subject to the consent of the manufacturer / supplier.
Work on electrical parts of the hand-held elding and extruding machines may only be
performed by an electrical engineer in compliance ith electro-technical rules.
Special risks:
All hand-held elding 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 ith these parts
because they may achieve temperatures of up to 350 °C.

Operating Instructions

Safety area:
The hot air stream of the hand-held elding 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 elding and extruding machines ithout 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 ater.
Safety:
Check for correct nominal voltage before connecting the hand-held elding and extruding
machine to the mains voltage.
Mains voltage must be identical to the nominal voltage sho n on the type plate of the hand-
held elding and extruding machine.
Pursuant to sec. 55 of VDE 0 100 the hand-held elding and extruding machine must be
operated using a protective s itch 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 elding 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 elding 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 elding and extruding machines are almost completely
assembled.
What remains to be done is to scre the enclosed handle to the machine.
For machines ith external air supply the air supply hose must be connected.
Ensure sufficient supply ith air hich is free of oil and ater (min. 300 l/min).
We recommend our air compressor, item no. DX 011. Connect extruder ith control box.
Weld shoe
The machine is supplied ith t o eld shoes blank hich 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 e ill supply t o eld
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 elding and extruding machines may not be used ithout air supply. This ould
inevitably result in damages of the extruder.
Before connecting the extruder to the mains supply please check that
- the On/Off s itch of the heating unit is in OFF position
- air supply is connected correctly
- the driving machine has not been put to permanent operation
- no s itch 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.
No put the On/Off s itch of the heating unit into ON position. The machine ill heat up to
the last selected temperature value. For information on ho to modify the desired
temperature value please refer to the section on the adjustment of the controlling unit.

Changing the welding filler
Heat up the hand-held elding and extruding machine until operating temperature is reached
to ensure that no elding filler is present in the machine, remove the eld shoe and
exchange the die (caution, left-handed thread) by a ne one or by a die used ith the
material to be applied no .
Caution: Risk of burning when working on the heated machine
After removing the old die and before placing the ne one run the machine for approx. 1 min.
on ne Welding filler.
Interruption of welding operations
Never leave the hand-held elding and extruding machine unattended.
Air supply may not be broken.
Caution: When processing PVC or PVDF, hand-held elding and extruding machines may
not be stopped for more than 3 min.
In such a case or if elding operations are completed a cleaning run must be performed on
the machine for about 2 min. using PE or PP elding filler.
Switching-off the hand-held welding and extruding machine
Place hand-held elding and extruding machine onto the support stand included in the
scope of supply.
Put the On/Off s itch 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 ater or other substances to speed up the cooling process.
Maintenance
Al ays disconnect the machine from po er supply before performing any maintenance ork.
Maintenance ork 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 elding and extruding machine and
the drive unit must be cleaned, re-filled ith ne grease and tested.
This ork 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 orm and to re-grease the bearing
approximately every 200 operating hours.
