9GB
Repairs and/or maintenance
work must only be carried out
by qualified electricians.
Only use the welding cable
provided in the scope of
delivery.
During operation, the device
should not be positioned
directly on the wall, covered or
jammed between other devices
so that sufficient air can be
absorbed through the ventila-
tion slats. Make sure that the
device is correctly connected
to the supply voltage. Avoid
any form of tensile stress of
the power cable. Disconnect
the plug from the socket prior
to setting up the device in
another location.
If the device is not in opera-
tion, always switch it off by
pressing the ON/OFF switch.
Place the electrode holder on
an insulated surface and only
remove it from the holder after
allowing it to cool down for
15 minutes.
Pay attention to the condition
of the welding cable, torch
and the earth clamps. Wear
and tear of the insulation and
the live parts can lead to haz-
ards and reduce the quality of
the welding work.
Arc welding creates sparks,
molten metal parts and smoke.
Therefore ensure that:
All flammable
substances and/or materials
are removed from the work
station and its immediate
surrounding.
Ensure the work station is
ventilated.
Do not weld on containers,
vessels or tubes that contain or
contained flammable liquids or
gases. Avoid any
form of direct contact with the
welding current circuit. The
no-load voltage between the
electrode holder and earth
terminal can be dangerous,
there is a risk of electric shock.
Do not store the device in
a damp or wet environment
or in the rain. Protection
rating IP21S is applicable
in this case.
Protect your eyes using the
appropriate protective glasses
(DIN level 9–10), which are
fastened to the supplied weld-
ing mask. Wear gloves and
dry protective clothing that
are free of oil and grease
to protect the skin from expo-
sure to ultraviolet radiation of
the arc.

10 GB
Do not use
the welding power source to
defrost pipes.
Please note:
The light radiation emitted by
the arc can damage eyes and
cause burns to the skin.
Arc welding creates sparks
and drops of melted metal.
The welded workpiece starts
to glow and remains hot
for a relatively long period.
Therefore, do not touch the
workpiece with bare hands.
Arc welding can cause
vapours to be released that
may be hazardous to health.
Be careful not to inhale these
vapours.
Protect yourself from the harm-
ful effects of the arc and keep
people that are not involved
in the work away from the arc
maintaining a distance of at
least 2 m.
ATTENTION!
During the operation of the
welder, other consumers may
experience problems with the
voltage supply depending on
the network conditions at the
connection point. In case of
doubt, please contact your
energy supply company.
During the operation of the
welder, other devices may
malfunction, e.g. hearing aids,
cardiac pacemakers, etc.
zPotential hazards during
arc welding
There are a series of potential
hazards that can occur during
arc welding. It is therefore par-
ticularly important for the welder
to observe the following rules to
avoid endangering him/herself
and others and to prevent dam-
age to people and the device.
Work on the voltage side, e.g.
on cables, plugs, sockets etc.,
may only be carried out by
qualified electricians accord-
ing to national and local
regulations.
In the event of accidents,
disconnect the welder from the
mains voltage immediately.
If electrical contact voltages
occur, switch off the device
immediately and have it
checked by a qualified electri-
cian.
Always ensure good electrical
contacts on the welding current
side.
Always wear insulating gloves
on both hands during welding

11GB
work. These provide protection
from electrical shocks (no-load
voltage of the welding current
circuit), harmful radiations
(heat and UV radiation)
and incandescent metal and
splashes of slag.
Wear sturdy, insulating shoes.
The shoes should also insulate
when exposed to moisture.
Loafers are not suitable as
falling incandescent metal
droplets can cause burns.
Wear suitable protective cloth-
ing, no synthetic garments.
Do not look into the arc
without eye protection; only
use a welding mask with the
prescribed protective glass as
per DIN. In addition to light
and heat radiation, which can
dazzle or cause burns, the
arc also emits UV radiation.
Without suitable protection the
invisible ultraviolet radiation
can cause very painful con-
junctivitis which is not appar-
ent until several hours later.
Furthermore, UV radiation can
cause sunburn-like effects on
unprotected parts of the body.
Any persons in the vicinity of
the arc or helpers must also be
informed of the dangers and be
equipped with the necessary
protective equipment. If neces-
sary, set up protective walls.
Ensure an adequate supply
of fresh air whilst welding,
particularly in small spaces, as
it produces smoke and harmful
gases.
No welding work may be
carried out on containers that
have been used for storing
gases, fuels, mineral oils or
similar – even if they have
been empty for a long time–
as possible residues may
present a risk of explosion.
Special regulations apply in
rooms where there is a risk of
fire or explosion.
Welded joints that are subject
to heavy stress loads and are
required to comply with certain
safety requirements may only be
carried out by specially trained
and certified welders. Examples
of this are pressure vessels,
running rails, tow bars, etc.
ATTENTION! Always connect
the earth terminal as close as
possible to the point of weld to
provide the shortest possible
path for the welding current
from the electrode to the earth
terminal. Never connect the
earth terminal to the housing of
the welder! Never connect the

12 GB
earth terminal to earthed parts
far away from the workpiece,
e.g. a water pipe in another
corner of the room. This could
otherwise damage the pro-
tective bonding system of the
room you are welding.
Do not use the welder in a
moist environment.
Only place the welder on a
level surface.
Do not use the welder in the
rain.
The output is rated at an ambi-
ent temperature of 20 °C. The
welding time may be reduced
in higher temperatures.
Risk of electric shock:
Electric shock from a weld-
ing electrode can be fatal. Do not
weld in rain or snow. Wear dry
insulating gloves.
Do not touch the electrodes with
bare hands. Do not wear wet or
damaged gloves. Protect yourself
from electric shock with insulation
against the workpiece. Do not
open the device housing.
Danger from welding
fumes:
Inhalation of welding fumes can
endanger health. Do not keep
your head in the fumes. Use the
equipment in open areas. Use
extractors to remove the fumes.
Danger from welding
sparks:
Welding sparks can cause an
explosion or fire. Keep flammable
substances away from the weld-
ing location. Do not weld next to
flammable substances. Welding
sparks can cause fires. Keep a
fire extinguisher close by and an
observer should be present to be
able to use it immediately. Do
not weld on drums or any other
closed containers.
Danger from arc beams:
Arc beams can damage your
eyes and injure your skin.
Wear a hat and safety goggles.
Wear hearing protection and
high, closed shirt collars. Wear
welding safety helmets and filter
sizes in perfect condition. Wear
complete body protection.
Danger from electromag-
netic fields:
Welding current generates
electromagnetic fields. Do not use
if you have a medical implant.
Never wrap the welding cable
around your body. Guide weld-
ing cables together.

13GB
zWelding mask-specific
safety instructions
With the help of a bright light
source (e.g. lighter) examine
the proper functioning of the
welding shield prior to starting
with any welding work.
Weld spatters can damage the
protective screen. Immediately
replace damaged or scratched
protective screens.
Immediately replace damaged
or highly contaminated or
splattered components.
The device must only be oper-
ated by people over the age
of 16.
Please familiarise yourself with
the welding safety instructions.
Also refer to the safety instruc-
tions of your welder.
Always wear a welding mask
while welding. If it is not
used, you could sustain severe
lesions to the retina.
Always wear protective cloth-
ing during welding operations.
Never use the welding shield
without the protective screen
because this could damage the
optical unit. There is a risk of
damage to the eyes!
Regularly replace the protec-
tive screen to ensure good
visibility and fatigue-proof
work.
zEnvironment with
increased electrical
hazard
When welding in environments
with increased electrical hazard,
the following safety instructions
must be observed.
Environments with increased
electrical hazard may be encoun-
tered, for example:
In workplaces where the space
for movement is restricted,
such that the welder is working
in a forced posture (e.g.:
kneeling, sitting, lying) and is
touching electrically conductive
parts;
In workplaces which are
restricted completely or in part
in terms of electrical conductivity
and where there is a high risk
through avoidable or accidental
touching by the welder;
In wet, humid or hot work-
places where the air humidity
or weld significantly reduces
the resistance of human skin
and the insulating properties or
effect of protective equipment.

14 GB
Even a metal conductor or
scaffolding can create an envi-
ronment with increased electrical
hazard.
In this type of environment,
insulated mats and pads must
be used. Furthermore gauntlet
gloves and head protection made
of leather or other insulating
materials must be worn to insu-
late the body against Earth. The
welding power source must be
located outside the working area
or electrically conductive surfaces
and out of the welder’s reach.
Additional protection against a
shock from the mains power in
the event a fault can be provided
by using a fault-circuit interrupter,
which is operated with a leakage
current of no more than 30 mA
and covers all mains-powered
devices in close proximity. The
fault-circuit interrupter must be
suitable for all types of current.
There must be means of rapid
electrical isolation of the welding
power source or the welding cir-
cuit (e.g. emergency stop device)
which are easily accessible.
When using welders under
electrically dangerous conditions,
the output voltage of the welder
must be greater than 113 volt
when idling (peak value). Based
on the output voltage this welder
may be used in these conditions.
zWelding in tight spaces
When welding in tight spaces this
may pose a hazard through toxic
gases (risk of suffocation).
In tight spaces you may only
weld if there are trained individu-
als in the immediate vicinity who
can intervene if necessary.
In this case, before starting the
welding procedure, an expert
must carry out an assessment in
order to determine what steps are
necessary, in order to guarantee
safety at work and which pre-
cautionary measures should be
taken during the actual welding
procedure.
zTotal of no-load voltages
When more than one welding
power source is operated at
the same time, their no-load
voltages may add up and lead to
an increased electrical hazard.
Welding power sources must be
connected in such a way that the
danger is minimised. The indi-
vidual welding power sources,
with their individual control units
and connections, must be clearly

15GB
marked, in order to be able to
identify which device belongs to
which welding power circuit.
zUsing shoulder straps
Welding must not take place if
the welding power source or the
wire feed device is being carried
e.g. with a shoulder strap.
This is intended to prevent:
The risk of losing your balance
if the lines or hoses which are
connected are pulled
The increased risk of an
electric shock as the welder
comes into contact with the
earth if he/she is using a Class
I welding power source, the
housing of which is earthed
through its conductor.
zProtective clothing
At work, the welder must
protect his/her whole body by
using appropriate clothing and
face protection against radia-
tions and burns. The following
steps must be observed:
– Wear protective clothing
prior to welding work.
– Wear gloves.
– Open windows to guarantee
air supply.
– Wear protective goggles.
Gauntlet gloves made of a
suitable material (leather) must
be worn on both hands. They
must be in perfect condition.
A suitable apron must be
worn to protect clothing from
flying sparks and burns.
When specific work, e.g.
overhead welding, is required,
a protective suit must be worn
and, if necessary, even head
protection.
zProtection against rays
and burns
Warn of the danger to the
eyes by hanging up a sign
saying “Caution! Do not look
into flames!”. The workplaces
must be shielded so that the
persons in the vicinity are
protected. Unauthorised per-
sons must be kept away from
welding work.
The walls in the immediate
vicinity of fixed workplaces
should neither be bright
coloured or shiny. Windows
up to head height must be
protected to prevent rays
from penetrating or reflecting

16 GB
through them, e.g. by using
suitable paint.
zEMC Device Classification
According to the standard
IEC 60974-10 this is a welder
in electromagnetic compatibility
Class A. Class A devices are
devices that are suitable for use
in all other areas except resi-
dential areas and areas that are
directly connected to a low-volt-
age supply system that (also)
supplies residential buildings.
Class A devices must adhere to
the Class A limit values.
WARNING NOTICE: Class A
devices are intended for use in
an industrial environment. Due to
the power-related as well as the
radiated interference variables,
difficulties might arise in ensuring
electromagnetic compatibility in
other environments.
Even if the device complies
with the emission limit values in
accordance with the standard,
such devices can still cause
electromagnetic interference in
sensitive systems and devices.
The user is responsible for faults
caused by the arc while working,
and the user must take suitable
protective measures. In doing
so, the user must consider the
following:
– network, control, signal and
telecommunication lines
– computers and other micropro-
cessor-controlled devices
– TVs, radios and other playback
devices
– electronic and electrical safety
equipment
– people with cardiac pacemak-
ers or hearing aids
– measurement and calibration
devices
– interference immunity of other
equipment nearby
– the time of day at which the
work is being done.
The following is recommended
to reduce possible interference
radiation:
– equip the mains connection
with a mains filter
– service the device regularly and
keep it in good condition
– welding cables should be
completely uncoiled and run as
close to parallel with the floor
as possible
– if possible, devices and systems
at risk from interference radi-
ation should be removed from
the work area or shielded.
Note!
This device complies with
IEC 61000-3-12, provided that

17GB
the Ssc short circuit power is
larger or equal to 2932.5 kW at
the interface point between the
operator’s supply and the public
supply. It is the responsibility of
the installer or user of the device,
after consultation with the distribu-
tion system operator if necessary,
to make sure that the device is
only connected to a supply with
an Ssc short circuit power which
is larger or equal to 2932.5 W.
Note!
The device is only for use in

thickness of Ø 0.9mm. The wire must be
positioned in the front groove!
Erect the feed roll holder
30
again and
screw in a clockwise direction.
Remove the burner nozzle
9
by turning
it anti-clockwise (see Fig. K).
Unscrew the welding nozzle
15
(see Fig. K).
Guide the cable assembly
12
away from the welder as straight as
possible (place it on the floor).
Take the wire end out of the edge of the
spool (see Fig. L).
Trim the wire end with wire scissors or
a diagonal cutter in order to remove the
damaged, bent ends of the wire
(see Fig. L).
Note: The wire must be kept under
tension the entire time in order to avoid
a releasing and a roll out! Therefore it is
recommended to carry out the work with
an additional person.
Push the flux cored wire through the wire
feed guide
31
(see Fig. M).
Guide the wire along the feed roll
19
and push it into the cable assembly
holder
32
(see Fig. N).
Swivel the thrust roller unit
28
towards
the feed roll
19
(see Fig. O).
Mount the adjustment
27
screw (see Fig.
O).
Set the counter pressure with the
adjustment screw. The welding wire must
be firmly positioned between the thrust
roller and feed roll
19
in the upper guide
without being crushed (see Fig. O).
Switch on the welder on the main
5
switch.
Press the torch button
11
.
Now the wire feed system pushes the
welding wire through the cable assembly
12
and the torch
10
.
As soon as 1 – 2 cm of the wire pro-
trudes from the torch neck
33
, release the
torch
11
button again (see Fig. P).
Switch off the welder on the main switch.
Screw the welding nozzle
15
back on.
Make sure that the welding nozzle
15
matches the diameter of the welding
wire used (see Fig. Q). When using the
delivered welding wire (Ø 0.9 mm), the
welding nozzle
15
with the labelling
0.9 mm must be used.
Screw the burner nozzle
9
back onto
the torch neck
33
(see Fig. R).
Always unplug the mains
plug from the socket prior to each mainte-
nance task or preparatory work in order to
prevent the risk of an electric shock, injury or
damage.
zUsing the device
zSwitching the device on
andoff
Switch the welder on and off on the main
5
switch. If you do not intend to use the
welder for an extended period, remove
the plug from the power socket. This is
the only way to completely de-energise
the device.
zSetting the welding current
and wire feed
The control dial
7
on the front of the welder
can be used to adjust the material thickness
to be welded. Power and wire feed are
controlled automatically.

Overload protection
The welder is protected against overheating
by means of an automatic protection device
(thermostat with automatic restart). The
protective device interrupts the overload of
the current circuit and the yellow overload
protection control lamp
8
illuminates.
Allow the device to cool down (approx.
15 minutes) for the activation of the
protection device. As soon as the yellow
overload protection control lamp
8
goes
out, the device is ready for operation
again.
The protection of the supply lines to the
mains sockets must comply with the reg-
ulations (VDE 0100). Shockproof sockets
must be protected to max. 16 A (fuses or
circuit breaker) The use of higher levels
of protection could result in a line fire or
structural fire damage.
Welding protection shield
HEALTH HAZARD!
If you do not use the welding protection
shield, harmful UV radiation and heat
emitted by the arc could damage your eyes.
Always use the welding protection shield for
welding work.
zWelding
RISK OF BURNS!
Welded workpieces are very hot and can
cause burns.
Always use pliers to move hot, welded
workpieces.
Please proceed as follows once
you have electrically connected the
welder:
Connect the earthing cable to
4
the
workpiece that is to be welded using
the earth clamp. Please ensure good
electrical conductivity.
The area to be welded on the workpiece
must be free of rust and paint.
Select the material thickness using the
control dial
7
.
Switching the device on.
Hold the welding protection shield
23
in
front of your face and guide the burner
nozzle
9
to the position on the work-
piece that is to be welded.
Press the torch button
11
, in order to
generate an arc. Once the arc is burning,
the device feeds wire into the weld pool.
If the welding lens is big enough, the
torch
10
is slowly guided along the
desired edge. The distance between the
burner nozzle and workpiece should
be as small as possible (it must not be
greater than 10 mm).
If necessary, oscillate a little to increase
the size of the weld pool.
The penetration depth (corresponds to

20 GB
the depth of the welding seam in the
material) should be as deep as possible
without allowing the welding pool to fall
through the workpiece.
The slag can only be removed from
the seam once it has cooled down. To
continue welding an interrupted seam:
First remove the slag at the starting point.
The arc is ignited in the weld groove,
guided to the connection point, melted
properly and finally the weld seam is
continued.
CAUTION! Please note that the torch
must always be placed on an insulated
surface after welding.
Always switch off the welder after
completing welding work and during
breaks and pull the plug from the mains
socket.
zCreate a weld seam
Forehand welding
Push the torch forwards. Result: The pene-
tration depth is lower, broader weld width,
flatter weld bead (visible surface of the
seam) and greater fusion error tolerance.
Backhand welding
The torch is dragged from the weld seam
(Fig. S). Result: Greater penetration depth,
narrower weld width, higher weld bead and
lower fusion error tolerance.
Welded joints
There are two-basic types of joints in
welding: Butt welds (outer edge) and angle
welding (inner edge and overlapping).
Butt welds
With butt welds of up to 2 mm material
thickness, the weld edges are completely
brought together.
For greater thicknesses, a gap of 0.5–4 mm
must be selected. The ideal gap depends
on the welded material (aluminium or steel),
the material composition as well as the
type of welding selected. This gap should
be determined by welding on a sample
workpiece.
Flat butt welds
Welds should be made without interruption
and with a sufficient penetration depth.
Therefore, it is extremely important to be
well prepared. The quality of the weld
result is affected by: the amperage, the gap
between weld edges, the inclination of the
torch and the diameter of the welding wire.
The steeper you hold the torch against the
workpiece, the higher the penetration depth
and vice versa.
S
To forestall or reduce deformations that
can happen during the material hardening
process, it is good to fix the workpiece
with a device. Avoid stiffening the welded
structure to prevent cracks in the weld.
These problems can be avoided if there is a
possibility of turning the workpiece so that
the weld can be carried out in two passes
running in opposite directions.
Welds on the outer edge
The preparation for this is very simple
(Fig. T, U).
