Intended Use
This unit is intended for self-shielded flux-cored arc
welding using the appropriate wire. Additional gas
is not required. The inert gas is contained in a pow-
dered form in the wire, is therefore fed directly into
the arc, and this makes the tool wind-resistant while
working outdoors. Only suitable wire electrodes may
be used for the unit. Intended use also involves ob-
serving the safety instructions, assembly instructions
and operating instructions in the instruction manual.
The applicable accident prevention regulations are
to be adhered to as strictly as possible. The unit
may not be used:
- in insufficiently ventilated spaces,
- in a damp or wet environment,
- in explosive environments,
- for the purposes of thawing pipes,
- in the vicinity of people with pacemakers and
- in the vicinity of inflammable materials.
Only use the product as described and for the
specified purpose. Keep these instructions in a safe
place. When passing this product on to others, please
also include all the documents. Any use other than
the intended is prohibited and potentially dangerous.
Damages resulting from noncompliance or misuse
are not covered by the warranty and are not included
in the manufacturer's liability.
Residual risk
Even if you use the unit correctly, there will always
be residual risks. The following hazards can arise
due to the design and performance of this flux-cored
arc welding unit:
- Eye damage due to being dazzled,
- Touching hot parts of the unit or the work piece
(burns),
- In the case of insufficient protection, a risk of
accidents and fire exists due to sparks or slag,
- Harmful gas and smoke emissions in the case of a
lack of air and/or insufficient extraction in enclosed
spaces.

Safety instructions
During use the equipment should
not be located directly against a
wall, be covered, or be jammed
between other equipment to en-
sure ample air can be taken in
through the ventilation louvres.
Verify the equipment is correctly
connected to the mains voltage.
Avoid any tensile load on the
mains. Unplug the mains plug
from the socket before transfer-
ring the equipment to a different
location.
Always switch the equipment off
with the ON/ OFF switch when
not in use. Set the electrode
holder down on an insulated
pad and allow to cool for
15 minutes before removing the
electrodes from the holder.
Pay attention to the condition of
the welding cables, the electrode
holders and the earth terminals.
Worn insulation and conducting
parts can produce hazards and
reduce the welding quality.
Arc welding produces sparks,
melted metal parts and smoke.
Therefore note: Remove any
flammable substances and/or
materials from the work area
and its immediate surroundings.
Ensure the work area is ventilated.
Do not weld atop containers, re-
ceptacles or pipes, which do or
did contain flammable liquids or
gasses.
Avoid any
direct contact with the welding
circuit. The no-load voltage be-
tween the electrode holder and
earth terminal can be danger-
ous, there is a risk of electric
shock.
Do not store or use the equipment
in a moist or wet environment or
in the rain. The Protection Provision
IP21S applies in this respect.
Protect the eyes with the appro-
priate safety glass (DIN Grad
9-10) to be installed in the
included welding shield. Use
gloves and dry protective cloth-
ing free from oil and grease to
protect the skin from ultraviolet
rays and the arc.
Do not use the
welding power source to thaw
pipes.
Remember:
The arc ray can damage the
eyes and cause burns to the skin.
Arc welding produces sparks and
drops of molten metal, the welded
work piece begins to glow and
remains very hot for a relatively

Safety instructionsSafety instructions
long time. Therefore do not touch
the work piece with bare hands.
Arc welding releases noxious
fumes. Be careful not to inhale
these as best possible.
Protect yourself from the danger-
ous effects of the arc and keep
persons not involved in the work
at least 2m away from the arc.
ATTENTION!
Depending on mains conditions
at the connection point, operat-
ing the welding equipment may
interfere with the voltage supply
for other loads. When in doubt,
please contact your power sup-
ply company.
Operating the welding equipment
may interfere with the functional-
ity of other devices, e.g. hearing
aids, pacemakers, etc.
Safety hazards
during arc welding
Arc welding produces a variety of
safety hazards. It is therefore par-
ticularly important for the welder to
observe the following rules to avoid
putting himself and others in danger
and to prevent damage to persons
and the equipment
Only have work to the mains
voltage end, e.g. to cables, plugs,
outlets, etc. performed by a elec-
trically skilled person in accord-
ance with national and local
regulations.
In the event of an accident, im-
mediately disconnect the welding
equipment from the mains voltage.
If electrical contact voltage occurs,
immediately switch the equipment
off and have it inspected by an
electrically skilled person.
Always ensure good electrical
contacts on the welding current
end.
Always wear insulating gloves on
both hands whilst welding. These
will protect from electric shock
(no-load voltage of the welding
current), from hazardous rays
(heat and UV rays) and glowing
metal and weld splashes.
Wear solid, insulating shoes. The
shoes should also insulate when
exposed to moisture. Low shoes
are not suitable, as glowing metal
drops falling could cause burns.
Wear suitable protective clothing,
no synthetic garments.
Do not look into the arc with
unprotected eyes, only use a
welding shield with approved
protective glass per DIN. In

11GB/IE/NI
Safety instructions
addition to light- and heat rays
which could result in blinding or
burns, the arc also emits UV rays.
Without adequate protection,
this invisible ultraviolet radiation
causes very painful conjunctivitis
which is only noticed a few hours
later. UV rays further cause burns
similar to a sunburn in unprotected
areas of the body.
Persons near the arc or assistants
must also be informed of the risks
and outfitted with the necessary
protection. If necessary, set up
protective panels.
Ensure an adequate supply of
fresh air whilst welding, particu-
larly in small spaces, as it produces
smoke and harmful gasses.
Do not weld containers in which
gasses, fuels, mineral oils, etc.
were stored - even if emptied a
long time ago - as residue poses
an explosion hazard.
Special regulations apply in rooms
posing fire- and explosion hazards.
Welded joints exposed to great
strain and needing to meet cer-
tain safety requirements must be
made by specially trained and
certified welders. Examples are
pressure vessels, running rails,
tow couplings, 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 welding
equipment!
Never connect the earth terminal
to earthed parts far away from
the work piece, e.g. a water pipe
in another corner of the room. This
could otherwise damage the
protective bonding system of the
room you are welding.
Do not use the welding equipment
in the rain.
Do not use the welding equipment
in a moist environment.
Only place the welding equip-
ment in a level location.
The output is rated at an ambient
temperature of 20°C. The weld-
ing time may be reduced in
higher temperatures.
Danger 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 electrode with bare hands. Do
not wear wet or damaged gloves.
Safety instructions

12 GB/IE/NI
Safety instructionsSafety instructions
Protect yourself from electric shock
by insulating from the work piece.
Do not open the equipment housing.
Danger due to welding
smoke:
Inhaling welding smoke can jeop-
ardize your health. Keep your head
out of the smoke. Use facilities in
open areas. Use ventilation to remove
smoke.
Danger due to welding
sparks:
Welding sparks can cause an
explosion or fire. Keep flammables
away from the welding area. Do
not weld next to flammables. Weld-
ing sparks can cause a fire. Keep a
fire extinguisher nearby and an ob-
server ready to use it. Do not weld
on top of drums or any closed con-
tainers.
Danger due to arc rays:
Arc rays can damage the eyes and
injure the skin. Wear a hat and
safety goggles. Wear hearing
protection and a closed, high shirt
collar. Wear welding helmets and
proper filter sizes. Wear full per-
sonal protection.
Danger due to electromag-
netic fields:
Welding current produces electro-
magnetic fields. Do not use along
with medical implants. Never wrap
the welding cables around the
body. Consolidate welding cables.
Safety notices specific to
the welding shield
Using a hot light source (e.g.
lighter) always check the weld-
ing shield is working properly
before starting to weld.
Welding splashes can damage
the glass shield. Replace dam-
aged or scratched glass shields
immediately.
Promptly replace damaged or
heavily soiled/splashed compo-
nents.
The equipment may only be
operated by persons who have
turned 16.
Familiarise yourself with the safety
instructions for welding. Also refer
to the safety instructions of your
welding equipment.
Always use the welding shield
when welding. Failure to use the
shield may result in serious inju-
ries to the retina.

13GB/IE/NI
Safety instructions
Always wear protective clothing
when welding.
Never use the welding shield
without protective glass, as the
optics can otherwise be damaged.
Replace the protective glass
early to ensure good visibility
and fatigue-proof working.
Tight and moist spaces
When working in tight, moist or
hot spaces, use insulating pads
and intermediate layers in addi-
tion to gauntlet gloves made from
leather or other insulating mate-
rials to insulate the body from
earth.
When using welding equipment
in electrically dangerous condi-
tions, e.g. in tight spaces from
conductive walls (kettles, pipes,
etc.), in wet spaces (soaking of
work clothes), the output voltages
of the welding equipment may
not be higher than 48 Volts (rms
value) in open loop. Based on
the output voltage this welding
equipment may be used in these
conditions.
Protective clothing
Whilst working the welder must
be protected against rays and
burns all over the body with the
appropriate clothing and face
protection. Remember the follow-
ing steps:
- Put on protective clothing before
welding.
- Put on gloves.
- Open windows or vent to ensure
air supply.
- Wear safety goggles and a
mask.
Wear gauntlet gloves made
from suitable material (leather)
on both hands. These must be in
good condition.
Wear suitable aprons to protect
the clothing from sparks and
burns. When required based on
the working method, e.g. welding
overhead, wear a protective suit
and, if necessary, a head guard.
Protecting against
rays and burns
Mark the work area with a
sign „Danger! Do not look into
flames!“ to indicate the risk to
the eyes. If possible, shield the
Safety instructions

Safety instructions/Before Use/AssemblySafety instructions
work areas to protect persons
nearby. Keep unauthorised per-
sons away from the welding area.
Walls in the direct vicinity of fixed
work areas should be neither
light coloured nor glossy.
Protect windows against rays
passing through or reflecting at
a minimum to head height, e.g.
with suitable paint.
EMC Device Classification
This is a welding unit with Class A
electromagnetic compatibility in ac-
cordance with the IEC 60974-10
standard. Therefore, it fulfils the ap-
plicable requirements for industrial
and domestic use. It may be con-
nected to the public low voltage
electricity supply in residential areas.
Even when the flux-cored arc weld-
ing unit complies with standardized
emission thresholds, electric arc
welding units may cause electro-
magnetic interference in sensitive
systems and devices.
The user is responsible and must
undertake the appropriate safety
measures for interference which
results from arcs during the welding
process. In doing so, the user must
take the following into account in
particular:
- Power, control, signal and tele-
communications cables
- Computers and other microproces-
sor-controlled devices
- Televisions, radios and other play-
back devices
- Electronic and electric safety
equipment
- People with pacemakers or hearing
aids
- Measuring devices and calibration
devices
- Interference immunity of other
devices in the vicinity
- The time of day during which
welding work is being carried out.
To reduce potential interference
radiation, it is recommended that
you:
- Equip the mains connection with a
mains filter or shield it with a metal
pipe
- Regularly perform maintenance
work on the flux-cored arc welding
unit and keep it in good condition
- Weld cables should be as short
as possible, fully unwound and
run as parallel on the ground as
possible
- Potential equalization should be
provided

15GB/IE/NI
Safety instructions/Before Use/Assembly
- The work pieces should be prop-
erly earthed
- Devices and systems susceptible
to interference radiation should be
removed from the welding area if
possible or shielded.

To prevent the hazard of an
electrical shock, injury or damage, pull the mains
plug from the socket before maintainance or pre-
paring for work.
Initial Use
Switching the unit on and off
Switch the welding unit on and off using the
main switch 5. If you do not use the welding
unit for an extended period, pull the plug out
of the mains socket. It is only then that the unit
will not be supplied with any current.
Adjusting the welding current
You can adjust the desired welding current using
the switches 89on the front of the welding unit.
If, for example, the MIN switch 8and switch 1 9
are up, the welding current amounts to 40 A and
the duty cycle is 60 %.
If, for example, the MAX switch 8and switch 2 9
are down, the welding current amounts to 90 A
and the duty cycle is 10 %.
The required welding current depends on the weld-
ing wire diameter, the material thickness and the
desired weld penetration depth.
Adjusting the wire feeder
To achieve a consistent weld, the adjustment wheel
for the wire feeder 10 can be used to finely adjust
the wire feeder. It is recommended that you start
with a setting in the centre position and reduce or
increase the speed if necessary.
The required welding current depends on the weld-
ing wire diameter used, the material thickness, the
desired weld penetration depth and the gaps to be
bridged on the work pieces to be welded.
Overload protection
The welding unit is protected against thermal over-
load with an automatic protective device (thermostat
with an autorecloser). The overload protection inter-
rupts the process when the circuit has been over-
loaded and the yellow control lamp 6illuminates.
If the protective device has been activated, al-
low the unit to cool down (approx. 15 minutes).
As soon as the yellow control lamp for overload

19GB/IE/NI
Initial Use
protection 6turns off, the unit is ready to use
once more.
Welding helmet
HEALTH HAZARD! If you
do not use the welding helmet, harmful UV rays
and heat emitting from the arc can damage your
eyesight.
Always use the welding helmet when you weld.
Welding
RISK OF BURNS! Hot,
welded work pieces are very hot, meaning that you
can burn yourselves on them.
Always use a pliers to move hot, welded work
pieces.
After you have connected the welding
unit to the electricity supply, proceed as
follows:
Connect the earth cable with the earth terminal
4to the work piece to be welded.
Ensure that good electrical contact exists.
The workpiece should be free of rust and paint
on the area to be welded.
Select the desired welding current and the wire
feeder depending on welding wire diameter,
material thickness and desired weld penetra-
tion depth.
Switch on the unit.
Hold the welding helmet 20 in front of your
face and lead the burner nozzle 7along the
area of the work piece to be welded.
Press the burner button 12 to generate an arc.
When the arc burns, the unit feeds wire into the
weld pool.
If the welding spot is big enough, the burner
11 is slowly led along the desired edge.
The gap between the burner nozzle and work
piece should be as small as possible (in any
case, no more than 10mm).
If necessary, oscillate it gently to enlarge the
weld pool somewhat. For those who are less
experienced, it can be difficult to form a decent
arc i.e. the correct setting for the welding current
and wire feeder speed.
You can figure out the best welding current and
wire feeder speed settings by practicing on a
test piece. A well-adjusted arc has a soft, steady
humming sound.
The weld penetration depth should be as deep
as possible, however, the weld pool should not
fall through the work piece.
In the case of rough or harsh rattling, decrease
the wire feeder speed or switch to a higher
power setting (increase welding current).
If the wire feeder speed is too high and/or the
welding current is too low, the welding wire
may not melt properly and may dip into the
welding seam and into the work piece.
A quiet, dull sound with a flickering arc indicates
too low a wire feed.
Increase the wire feeder speed or switch to a
lower welding current.
The wire melts even before it has reached the
welding seam with a welding current that is too
high. The result is that drops form on the welding
wire, as well as spraying and an inconsistent
arc.
The slag may only be removed from the seam
when it has cooled down.
To continue the welding process on an inter-
rupted seam:
Firstly, remove the slag from the point of attach-
ment.
Ignite the arc in the weld groove, lead it to the
connection point, properly melt the material
there and then continue along the welding
seam.
CAUTION! Ensure that the burner is always
put down on an insulated surface after welding.
Always switch the welding unit after finishing
welding work and during breaks, and always
pull the mains plug out of the socket.

Creating a welding seam
Spot-welded seam or forehand welding
The burner is pushed forwards.
Result: The penetration depth is lower, seam width
is larger, weld bead is flatter and fault tolerance is
greater.
Pull-welded seam or backhand welding
The burner is pulled away from the welding seam.
Result: The penetration depth is higher, seam width
is smaller, weld bead is higher and the fault tolerance
is lower.
Welded joints
There are two basic joint types in welding technology:
butt welding and angle welding (outside edge, in-
side edge and overlapping).
Butt welded joints
For butt welded joints up to 2mm thick, the welding
edges are brought together completely.
For larger thicknesses, see the table below:
P
Flat butt welded joints
Welding processes should be carried out without
interruption and with a sufficient penetration depth.
Therefore, good preparation is essential.
Factors which effect the quality of the welding
results include: the welding current, the distance
between the welding edges, the burner tilt and the
respective welding wire diameter.
The steeper the burner is held in relation to the
work piece, the higher the penetration depth and
vice versa.
Q
To forestall or reduce deformations which could
arise during material hardening it is a good idea
where possible to fix the work pieces using a piece
of equipment which counteracts the contraction or
deformation of the material.
It is recommended that you avoid hardening the
welded structure to prevent fractures in the welded
seam. These difficulties can be reduced if you are
able to rotate the work piece in such a way that the
welding process can be carried out in two opposite
runs.

Preparation for this is very simple.

However, this is not practical for stronger materials.
In this situation, it is better to prepare a joint as
