Gases andn fumes
• Gases and aerosols that pose a health
hazard are formed in the process of
welding. Do not inhale these gases and
aerosols.
• Work in well-ventilated areas or use a
ventilation system that safely removes
harmful gases from the working area.
• When welding with electrodes requir-
ing special ventilation, for example,
electrodes for welding stainless steels,
cast iron and the like (see Material
Safety Data Sheet - MSDS, or data
on the original electrode package),
for welding of galvanized steels, lead
and cadmium-coated steels or others
metals, or coatings that produce highly
toxic gases, use local air extraction
systems or mechanical ventilation sys-
tems. If possible, remove coatings that
emit harmful gases from the welding
zone.
• When working in confined spaces
or under other circumstances, wear
a respirator while performing work.
Additional precautions are also neces-
sary when welding galvanized steel.
• Do not weld next to materials that
release toxic fumes when heated.
Vapors of cleaning agents, degreasing
compounds, paintwork and similar
materials can be very toxic when
heated.
• Protective gases used in welding, can
force air out of the breath zone of the
welder and cause serious breathing
disorders. Always provide sufficient
ventilation of the working area, espe-
cially in confined areas, to ensure
sufficient oxygen in the working area.

preparation can lead to fire and explo-
sion of fumes of flammables.
• Take safety measures to protect
nearby flammable materials from
sparks and drops of metal. For insula-
tion, put a piece of sheet metal or use
a dense, non-flammable fabric.
• Never weld freshly painted structures
and materials until the paint dries
completely.
• Sparks and drops of molten metal are
scattered in the process of welding.
They can get into the pockets and
clothing. Use tightly fitted clothing and
shoes with shut pockets. Do not allow
sparks to enter the gaps of wooden
decks and furniture.
• After finishing welding, make sure
that there are no smouldering objects
or drops of the molten metal in the
gaps. Before leaving work place, make
sure the smoke concentration is not
increasing.
• While welding never use clothing,
gloves and shoes with the traces of tar,
oil and other flammable liquid.
• Remove from the pockets flammable
and explosive objects, such as lighters
and matches.
• To avoid spontaneous starting of the
welding arc when the electrode holder
is in contact with the workpiece, do not
leave the switched on welding machine
unattended. Remove the electrode and
store the electrode holder on a safe
distance from a workpiece and other
objects which can create electrical
contact.
Hot surfaces
• The place of the weld and the adjacent
parts run hot and can cause severe
burns when in contact.
• Do not touch the workpiece until it
cools down completely.
• The TIG torch and the electrode are
also very hot. Do not touch them
immediately after finishing welding as
it can cause a burn.
• Do not remove the weld slag until it
cools down completely. The heated
slag may get into the eyes or on cloth-
ing and cause a burn.
Electromagnetic fields
• The magnetic field may effect the
operation of different electrical or elec-
tronic devices, e.g. pacemakers.
• Wearers of pacemakers or other vital
electronic equipment should consult
their physician before beginning any
arc welding.
• People with a pacemaker should be
kept away from welding area.
• Do not coil the cable around your body
while welding.
• If possible, twist together the electrode
holder cable and the negative clamp
cable.
• If possible, keep the electrode holder
cable and the negative clamp cable on
the same side.

skin. Do not look at the welding arc
without proper eye protection. Always
use a welding helmet that covers your
face.
• Choose the clear shade range of the
welding lens in accordance with the
level of the welding current. For the
most common welding modes, a range
of 9-13 DIN is sufficient. For cold
running, a clear shade range of 5-9
DIN may be required. Modern welding
helmets allow smooth adjustment of
the clear shade range. The table below
provides the values of the clear shade
according to the type of welding and
welding current.
• UV and IR rays are dangerous to
uncovered skin and can cause skin
burns.
• Suitable protective flameproof clothing
must be worn at all time.
• The welding arc rays reflected from
walls and nearby objects, can cause
burns of the eye cornea and uncovered
skin areas in nonwelders. To protect
others, use flame proof screens or
natural barriers.
• If there are other people in the welding
area, warn them of the danger each
time before starting the welding arc so
that they can protect themselves from

General welding information
General welding
information
Semiautomatic welding machine is
designed for manual inert-gas arc weld-
ing. The shielding gas or gas mixture
may consist of the following: carbon
dioxide, argon or their mixture.
The welding machine has a metal
case with an opening wall. On the
front panel there is the welding current
selector, the wire feed speed control,
the power indicator, alarm indicator. The
machine is equipped with a forced venti-
lation system, therefore, it is strictly for-
bidden to cover any ventilation openings
in the metal case.
The principle of semiautomatic
welding machine. The machine converts
an AC voltage of 50Hz into a 400V DC
voltage that is converted to a high-fre-
quency modulated voltage and rectified.
Welding is carried out by a melted elec-
trode in a shielding gas environment.
The electrode is a metal wire fed by feed
rolls into the weld pool.
The shielding gas is fed to the
welding pool from the attached cylinder
through the solenoid valve. The machine
has built-in protection against overheat-
ing and is equipped with current adjust-
ment conrol and wire feeder control,
depending on the material and the thick-
ness of the workpiece to be welded.
Component overview
1. MMA welding current. Welding
current is selected depending on the
electrode diameter and thickness of the
workpiece.
2. Power indicator. Indicates that the
welding machine is connected to the
electrical power supply.
3. Alarm indicator. If the alarm indi-
cator light is on, the machine is over-
heated. When the breaker has tripped,
the power flowing to the electrical
circuit is interrupted, but the cooling
fan keeps working. After the operating
temperature has been restored, the cur-
rent supply to the output of the welding
machine is automatically switched on.
4. MIG wire feed speed control
The welding current depends on the
feed rate of the electrode wire. The wire
feed speed prevents excessive weld
spatter, wire sticking to the workpiece or
arc breaking.
The wire feed speed is selected
experimentally and depends on the
wire diameter, the thickness of the
weld metal and the qualification of the
welder.
When welding current increases,
weld penetration increases too, it leads
to an increase in the proportion of the
base metal in the seam. The width of
the seam increases slightly at first, and
then decreases.
5. Arc voltage regulator
When arc voltage increases, weld
penetration decreases and the width of
the seam increases. Excessive increase
in arc voltage leads to increased spat-
tering of melted metal, deterioration of
the gas shield and formation of pores in
the weld metal.
The arc voltage is set depending on
the selected welding current amperage.

MIG installation
1. Make sure that the welding
machine is unplugged.
2. Attach the cable with the terminal
«Mass» to the negative clamp of the
welding machine.
3. Attach the torch to the MIG torch
line cable inlet (see Fig. page 11, item 9).
4. Choose polarity. The manufacturer
preset polarity of the welding machine
for operation without shielding gas
(using a flux-covered wire). For this
setting, the MIG torch is connected to
the «-» terminal (2), the earth cable is
connected to the positive «+» terminal (4).
If needed to carry out work using the
shielding gas, connect the MIG torch to
the positive terminal «+» (4) and connect
the earth cable to the «-» terminal (2).
Reversal of polarity is carried out in
the wire feeder
After choosing the correct polar-
ity, make sure that the terminals are
securely tightened.
5. Shielding gas: Carbon dioxide
(CO2) or gas mixtures are used as
shielding gas. Most often mixture of
carbon dioxide and argon (CO2+Ar) is
used.
For most work with welding car-
bon-structural steels, it is recommended
to observe a proportion of 82% of argon,
18% of carbon dioxide. This combina-
tion reduces weld spatter and and sheet
metal burning.
For stainless steel, a mix of Helium,
Argon and CO2is used.
100% Argon is used for aluminum.
Note: There is a large number of
gas mixtures for carring out weld-
ing work with various metals. If
you need help in choosing shield-
ing gas, contact professionals.
Weld work without the use of
shielding gas is possible only with
a special flux-covered wire. When
welding with a flux-covered wire,
it burns to form the shielding gas.

Basic settings
Basic settings
Welding speed. When welding speed
increases, all seam dimensions are
reduced. Welding speed is set depend-
ing on the thickness of the metal to be
welded to achieve good shaping of the
seam. If welding speed is too high, the
end of the electrode can leave protec-
tion zone and oxidize in the air.
Slow welding speed causes an
excessive increase of the weld pool and
increases porosity in the seam.
Wire stickout. An increase in the
wire stickout results in deterioration of
arc stability and weld shaping, it also
leads to increased spattering of the
melted metal. Shortened amount of wire
stickout makes it difficult to observe the
welding process, causing frequent burn-
ing of the torch gas nozzle. Determening
the amount of wire stickout to use
and the distance between the torch
nozzle and the metal surface, depends
on wire’s diameter. The length of the
amount of stickout and the distance
from the torch nozzle to the metal sur-
face, is set depending on the selected
diameter of the electrode wire.
The shielding gas consumption
mainly depends on the chosen electrode
wire diameter, but the welding speed,
the product configuration and the pres-
ence of air movement, i.e. drafts, wind,
etc have to be taken into consideration.
To improve gas protection in these
cases, it is necessary to increase the
consumption of protective gas, reduce
the welding speed, bring the nozzle
closer to the metal surface or use pro-
tective shields.
The inclination of the electrode along
the seam has a great impact on the
depth of the penetration and the quality
of the seam. When welding forehand, it
is harder to observe the weld formation,
but it is easier to see the welded edges
and to guide the electrode exactly along
the gap between them. The seam gets
wider while the depth of the penetration
decreases. Forehand welding is recom-
mended for welding metals of shallow
thickness when there is a danger of
a burn through. Backhand technique
offers a better view of the welding area,
better penetration when the weld metal
gets more solid.

Type of welding current and polarity.
Gas-shielded welding is carried out by
reversed polarity direct current. Therein,
the «+» is applied to the welding torch,
and «-» to the workpiece. Welding with a
semi-automatic welding machine with-
out gas feeding is performed by direct
current of direct polarity.

MIG operation
6.4. Adjust the pressure roll force
(see Fig. 13, tem 3) so that it is not
clamped too tightly, and the wire does
not slip. Excessive clamping will lead to
premature wear of the pressure roll, while
slippage will complicate the welding
process.
6.5. Remove the MIG nozzle and a
conductive head from the torch, press
the torch trigger, pull the wire until it
emerges from the torch port.
6.6. Connect the conductive head
that exactly matches the wire diameter
to the torch and place the nozzle back
to its place.
6.7. Adjust the length by clipping off
the end of the wire with insulated cutters.
Repeat each time before starting work.
MIG operation
WARNING! Never operate the
maching in wet weather or in a
humid room.
Never use cutting tools (drills,
grinders, electric saws, etc.) next
to the machine. Metal dust may
enter the machine and it will lead
to its damage.
Never carry out welding work if wire
or main supply cables are damaged.
Before switching on, keep the
machine for at least two hours at
a positive ambient temperature to
prevent condensation.
1. Turn on the power switch (see Fig.
p. 11, item 12), the power indicator light
will turn on (see Fig. p.11, item 2).
2. Select the MIG mode with the machine
mode switch (see Fig. p.11, item.6).
3. Set the desired value with the weld-
ing current selector (see Fig. p.11, item 5).
The welding current selector controls
the temperature of the welding arc.
4. Positioning of the MIG welding
torch: The best position of the welding
torch is the position convenient to com-
fortably hold it. In the process of using
your welding machine, try to keep the
torch in various positions until you find
the most convenient for you.
There are two major torch angles
which must be taken into account when
carring out welding works.
Angle A may vary, but in most cases it
should be 60°. This is the angle at which
the torch handle is parallel to the weld-
ing seam. When the angle is greater,
the fill rate is higher. When the angle is
smaller, the fill rate is lower.
Angle B can be applied in two cases:
to better see the arc for greater control
of the pool fill rate and for arc force
control.
5. The distance between the con-
tact head of the welding torch and the
surface to be welded must not change
and should not exceed 6mm. A greater
distance will result in the welding

5.1. Connecting gas cylinder: Install
the gas cylinder on the prepared sur-
face. If necessary, fix it to avoid tipping
over.
ATTENTION! Observe safety rules
when working with a gas cylinder!
5.2. Attach the gas regulator to the
cylinder valve.
5.3. Attach the gas hose of the gas
cylinder regulator outlet to the gas cylin-
der connector (see Fig. p. 11, item 11).

5 – Gas flow meter gauge;
6 –Gas cylinder connector;
7 –Gas cylinder.
5.4. Set the required gas flow by turn-
ing the regulator knob.
Note: The wire diameter, welding
current and welding speed affect gas
consumption. The average gas
consumption for welding construc-
tional steels with a welding wire diam-
eter of 0.8 and 1.0mm with welding
current of 60-160 is 8-9 l/min.
Gas consumption for non-ferrous
metals is usually 1.5-2 times higher.
When working in windy conditions
outside or inside in a draught,
protect the welding area from
blowing-out of the shielding gas.
5.5. Connect the device to the power
supply and switch on the automatic
switch on the back panel (see Fig. p. 11,
item 12).
5.6. Press the torch trigger and make
sure that the gas flows through the
gas valve into the torch. The gas valve
is located on the back of the welding
machine panel and is activated by press-
ing the trigger on the MIG torch. When
gas flows, listen for a hissing sound.
6. Electrode wire. The type and thick-
ness of the wire is selected depending on
the chemical composition of the material
to be welded and its thickness. Welding
wire diameter is selected in accordance
with the required welding current level.
Most often, a wire with a diameter of
0.8 mm is sufficient for welding metal
with a thickness of 1 to 4 mm. The most
common wire brand for welding car-
bon-constructional steels is ER70S-6.
6.1. Install the wire weld coil in the
feeder (see Fig. p. 13, item 1).
6.2. Make sure that the deflector roll
is installed in a way that the groove
matches the wire diameter. If needed,
turn the roll over by untwisting the lock-
ing screw (see Fig. p. 13, item 5).
6.3. Insert the wire into the feeder
and press it with the pressure roll (see
Fig. p. 13, item 3).

ATTENTION! Disconnect power
source before performing any
maintanence work.
Long service life and efficient oper-
ation of the welding machine directly
depend on its technical condition.
Regularly monitor the machine con-
dition. If damage occurs, repair the
machine immediately. Do not oper-
ate the machine in overload condi-
tion. Strictly observe the switching
frequency. Avoid impacts or other
mechanical damage of the case and the
machine operational panel. Do not keep
the machine in moist or damp areas.
Inverter welding machine is a reli-
able equipment. Observance of simple
safety rules and timely maintenance can
significantly increase the operational
lifespan.
Keep the welding machine in good

6. Setting the wire feed speed: The
wire feed speed control (see Fig. 11,
item 4) controls the speed of the wire
that is being fed through the MIG torch.
The wire feed speed must be precisely
set at the level when the wire fully
melts. When setting the wire feed speed,
check the wire type, diameter, volt-
age and positioning of the seam. The
welding current changes if the wire feed
speed adjusted.
NOTE: The wire will move faster
if you do not strike the welding
arc. On the contrary the wire feed
speed will be lower if you strike
the welding arc.
7. Connect the earth terminal to the
metal part identical to the one you will
be welding on. The metal part should be
the same thickness or slightly thicker
than the workpiece. Clean the workpiece
before you start welding.
8. Adjust the required welding
voltage.
9. Bring the torch close to the work-
piece, make sure to position the torch
following the recommendations of this
manual.
10. With your free hand, turn the wire
speed control knob to the maximum and
keep holding the knob.
11. Draw the protective mask and
press the MIG torch trigger to strike the
arc, start moving the torch forehand
or backhand, simultaniously turn-
ing the wire feed speed control knob
counterclockwise.
12. While adjusting the wire feed
speed, the sound produced by the
welding arc will change from the sharp
buzzing sound to a slight sizzling bacon
sound. If you reduce wire feed speed
too much, you will hear a sharp sound
and bangs. The wire feed speed is
correct when you hear a steady sizzling
sound. By slightly changing the wire
feed speed, you can control the tem-
perature and fill rate of the weld when
the arc voltage settings are set and not
changed. Repeat the above procedure if
you have adjusted the voltage, diameter
or type of the welding wire.
13. After welding operations are
completed, set all the controls to the
minimum position, close the valve on
the cylinder and unplug the machine.
MMA operation
ATTENTION! Follow the safety
rules! Start work only in appro-
priate tightly woven clothes and
closed boots. Welding gloves and
a mask must be worn at any time!
If the welding machine was used
for welding in the MIG mode, take the
following steps to prepare it for opera-
tion in the MMA welding mode (covered
electrode welding):
1. Unplug the welding machine.
2. Turn the gas cylinder valve off and
disconnect the hose from the socket on
the back of the welding machine.
3. Disconnect the MIG torch. Loose
the feeder deflector roll and coil the wire
onto the spool.
4. If the polarity of the negative termi-
nal has been changed to «+», restore it.
(See step 4 on page 13 of this manual).
5. Connect the welding cables to the
machine: connect the electrode holder

Inverter welding machine is a com-
plex electronic device. Only authorised
electricians should carry out repairs and
internal servicing. Contact an autho-
rized service center.
The machine should periodically be
cleaned of dust, dirt, lubricants, etc.
Keep the ventilation grids clean.
Every six months or when necessary,
remove the welding machine cover and
blow the internal parts of the welding
machine from the accumulated dust
with a compressed air gun.
ATTENTION! It is allowed to
remove the cover for cleaning
the internal parts of the device
only after the end of the warranty
period. If you need to clean the
device earlier within the warran-
ty period, contact an authorzed
service center.
Timely replace a damaged power
cord, ground cable, earth terminal, or
electrode holder.
Storage and transportation
1. Store the welding machine at an
ambient temperature ranging +10°C to
+50°C, at a relative humidity not exceed-
ing 80%. Storage room should be free
from dust, acid vapors and alkalis.
2. Keep the machine away from water
and snow. Pay attention to the packag-
ing signs. The storage container must
be dry, free from corrosive gas or dust
and must have good air circulation.
3. Before storing the machine, clean
it, put it first in a plastic bag and then in
a storage box.
