Recommendations on the machine op-
eration
Preliminary works (see g. 7)
•Clean welding surfaces from rust and paint coatings�
•The edges of pieces to be welded should be ma-
chined if welding blanks width is more than 1 mm (see
g. 7.1).
•Please remember that a large quantity of heat is
released during welding which can damage the sur-
rounding items, therefore, carefully choose the site
and take appropriate actions to prevent re.
Electrodes
The right choice of electrodes, to a great extent, pre-
determines the welding seam quality and the operation
speed� Before purchasing electrodes, carefully
examine the recommendations of their use� Consult a
specialist if necessary� It is also important to observe
the electrode storage conditions�
General operation recommendations
The recommendations below apply to all
machines connected through a socket
connector. In the case of stationary con-
nection the machine assembly and net-
work connection will be done beforehand.
•Place the machine in an even, dry, not vibrating
surface observing all above-mentioned safety proce-
dures�
•Connect the ground wire�
TIG welding (see g. 7)
•Connect gas feeding, earth terminal cable, and
welding torch to the machine� Connect earth clamp 41
to socket "+" 5�
•Fix earth clamp 41 on one of the parts to be weld-
ed�
•Connect the machine to the mains and switch it on�
•Select the TIG welding mode as described above�
•Slightly open the valve of gas pressure regulator 53
and turn on the valve of gas cylinder 55� Push and
hold button of welding torch 42, gas will come from a
ceramic torch nozzle 43; using the valve of gas pres-
sure regulator 53, set gas ow rate (l/min), necessary
for work performance; release the button of welding
torch 42�
•Set the welding current value�
•Adjust other process parameters as described
above, if necessary�
•Turn on welding torch 42 (as described above) and
light the arc:
•for the high-frequency ignition of the arc, bring
torch 42 to workpieces to be welded and hold it so
that the distance between tungsten electrode 61 and
a workpiece is 2-4 mm - a high-frequency discharge
will ignite the welding arc;
•for the contact ignition of the arc, touch the
workpiece with an end of tungsten electrode 61,
then slightly tilt and raise torch 42 until a 2-3 mm gap
forms between a tip of tungsten electrode 61 and the
workpiece - at this moment a welding arc will form�
•If you weld workpieces thicker than 1 mm, a rod of
proper diameter should be fed in arc burning area for
lling a welding seam.
•Hold welding torch 42 and a rod, as illustrated in
gures 7.2 and 7.3 (grey arrow shows a direction of
welding torch movement)� Move the welding torch 42
and rod along a welding seam, delivering a ller rod, as
it's consumed, in welding point�
•After completion of welding, release the button of
welding torch 42, but don't remove it, wait for crater lling
and cooling down of the shielding gas welding end�
•After completion of work, machine should cool down,
then disconnect it and close valve of gas pressure
regulator 53 and valve of gas cylinder 55�
MMA welding (see g. 8)
When describing MMA welding, elec-
trodes mean stick consumable elec-
trodes having coatings.
•Connect the welding cables to the machine� Weld-
ing can be performed with direct and reverse polarity�
The selection of polarity depends on the materials to
be welded and the recommendations on how to use
electrodes�
•Direct polarity - connect electrode holder 40 to
socket "-" 8, connect earth clamp 41 to socket "+" 5�
In such a mode the electrode heats less than the
basic metal, the electrodes get fused slower, the
welding joint is completed with a deeper penetration�
•Reverse polarity - connect electrode holder 40 to
socket "+" 5, connect earth clamp 41 to socket "-" 8�
In such a mode the work piece is heated less than
the electrode which can be used for welding high-
carbon, alloy and special steels sensitive to over-
heat as well as for welding sheet metal�
•Press the lever of the electrode holder 40 and install
the electrode end (the end free from coating) into elec-
trode holder 40 and then release the lever�
•Fix earth clamp 41 on one of the parts to be welded�
•Connect the machine to the mains and switch it on�
•Select the MMA welding mode as described above�
•Set the welding current value� The selection of
welding current depends on the electrode to be used,
thickness of material to be welded, spatial position of
a seam etc�
•Ignite the welding arc in one of two ways: ignition
by touching (see g. 8.1); ignition by scratching (see
g. 8.2).

English
•The main practices of welding electrode handling
are described below:
•usually welding is carried out with vertically po-
sitioned electrode or at its inclination concerning a
seam, in a corner forward or back� When welding by
a corner back, it is provided better fusion and smaller
width of a seam (but performance of work in this case
demands the certain skill);
•progressive motion of an electrode (see
g. 8.3) - on a direction of an axis of the electrode, for
maintenance of necessary arch length which should
make 0,5-1,1 of electrode diameter� The length of an
arch renders the serious inuence on quality of a weld-
ed seam and its form� A long arch causes intensive oxi-
dation and nitration of the fused metal, and increased
splashing of it;
•longitudinal movement of an electrode (see
g. 8.4) - for formation of a welded seam� Speed of
movement of an electrode depends on electric current,
electrode's diameter, type and spatial position of a seam;
at the high speed of an electrode the basic metal
has no time for fusion, what results in insufcient
depth of weld fusion spill is formed;
insufcient speed of moving of an electrode re-
sults in overheating and arc burn (through fusion)
of metal;
correctly chosen speed of longitudinal movement
along an axis of a welded seam allows obtaining its
width on 2-3 mm more than diameter of an electrode;
•lateral movement of an electrode (see g. 8.5) -
for formation of the widened welded seam� An elec-
trode is moved in lateral oscillatory movements more
often with constant frequency and the amplitude,
combined with progressive motion of an electrode
along an axis of the prepared groove, and to an axis
of an electrode� Lateral oscillations of an electrode
are various and are determined by the form, the
sizes, positions of a seam in space in which welding
is carried out, and skill of the welder� The width of
a welded seam in this case should not exceed 2-3
diameters of an electrode�
•Watch the electrode length and when 20-30 mm is left
to the electrode holder 41 jaws - replace the electrode�
•Wait for cooling down and crystallization of slag on
a welding seam upon which remove the slag using a
special hammer and a brush� You must wear protective
gloves or a mask when performing these operations�
•Check the welding seam quality and when the faults
are found remove them�
•Following the completion of work, let the machine
cool down, switch it off and then disconnect the cables�
Machine maintenance / preventive meas-
ures
Before carrying out any works on the machine it
must be disconnected from the mains.
Electrode sharpening (see g. 6.4-6.6)
Operations for non-consumable elec-
trodes (of tungsten or tungsten with ad-
ditives) only are described below.
Electrode end contamination or damage is made
because of touching the weld pool metal or a ller rod
by electrode, as well as because of a wrong selection
of shielding gas quantity, delivered to welding area�
The electrode should be sharpened properly and
timely�
During alternating current welding the electrode end
should be put into semi-spherical shape (see g. 6.4).
During direct-current welding the electrode end should
be put into conical shape� In general, sharpening cone
should be 2-2,5 of electrode diameters in length, a
sharpening angle should be 14°-60°� Sharpening cone
angle impact on arc form and metal penetration is
shown in gure 6.4.
Using the electrode with pointed end, weld very thin
metals (0,125-1 mm)� Welding thicker metal, blunt the
electrode end, otherwise it melts and tungsten enters
the welding seam�
Sharp the tungsten electrode axially, using a special
ne abrasive disk. Perform grinding operation in
direction of electrode length (see g. 6.5).
Don't sharpen the tungsten electrode as illustrated
in figure 6�6, it will result in unstable arc, it will im-
pair welding seam quality and make arc striking dif-
ficult�
Cleaning of the machine
An indispensable condition for a safe long-term ex-
ploitation of the machine is to keep it clean� Regularly
ush the machine with compressed air thought the
vent holes 1�
