Operating Instructions
DOHLE Hand Welding Extruder ExOn5
DOHLE Extrusionstechnik GmbH 19
1. Type
Article-no. / Type of machine : DX309 ExOn5
Machine no. :
.........
Required voltage : 400 V / 50 – 60 Hz
2. Safety
Pursuant to section 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. Al ays 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 there from.
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.
Caution: Heat can reach combustible materials!
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 2m is
observed in all directions.
Don’t concentrate the heat stream long time on the same area.
Operating Instructions

DOHLE Extrusionstechnik GmbH 20
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.
Overhead ork:
When orking overhead al ays ear appropriate safety devices (such as helmet,
savety glasses etc.).
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 elding 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 ater on hand-held elding 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 elding 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.
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 elding extruder
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:
- 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.
If you give no the po er supply plug to a suitable plug socket (230V, 16A), press that
On - Off s itch on the air heater on position ON.
The machine heats no up.
Make sure by each s itching on of the machine, that the on-off s itch of the drive
engine is s itched off.
After a heating-up time of approx. 15 minutes, start the machine using the elding material
ished by you and examine the air and elding material temperature ith a suitable
temperature measurement. By changing the temperature of the air heater consider the
reaction response time of the system.

Change of the elding shoe
In order to be sure that no more old elding rod is in the hand elding extrusion, heat up the
machine on operating temperature, remove the elding shoe and change the nozzle (note:
left hand thread!).
Changing the elding 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 .
Note: ith ork on heated machine burn danger.
When the nozzle is changed drive for approx. 1 min. the ne elding rod in the hand elding
extrusion.
Interruption of the elding
Do not leave the hand elding extruder unsupervised.
The air supply must remain maintained
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.
S itch off the hand elding extruder
Bring the potentiometer of the air heater in position 0 and pull after ca.2 minutes
the po er supply plug.
Note: Even after 15 minutes still exists burn danger on bright metal parts.
No ater or other materials for accelerating the cooling procedure must be used. .
Maintenance
Before maintenance ork on the equipment, pull po er supply plug!
Maintenance ork may be accomplished only by electrical specialists.
Consider the security chapter!
After approximately 500 operation hours the hand elding extruder, including the drive unit
must be cleaned, greased and controlled. These ork may be implemented only by electrical
specialists.
Drive
The carbon brushes conductors of the drive must be examined approx. every 200 operation
hours and rene ed if necessary.
Deep groove ball thrust bearing /barrel extruder
The deep groove thrust bearing and the barrel extruder should be cleaned approx. every
200 operation hours and again be greased
Note: Only high temperature grease can be used. Our art. no.: D-0581
