APPLICATION
GETTING STARTED
The procedure for preparing the welding machine to work
Inverter welding machinecan be used in stationary conditions (at service
stations vehicles, construction sites, home and garden land, garages, etc.)
and in the field in mobile systems equipped with gasoline or diesel mini power
stations.
1. Carefully remove the welding machine out of the box, do not apply shock
or mechanical impact on the parts of the product.
2. Place the unit on a horizontal surface.
3. Visually inspect the product for mechanical damage on the body of the
welding machine, welding cable, power supply and cables.
4. Check the BNC connectors, clips, electrode holders and "mass".
5. Ensure that the surface on which the welding machine is installed and
that there is enough space (at least 0.5 m on each side and from the top) to
ensure proper operation of the ventilation system.
6. Make sure the power switch (button «ON / OFF») is in position «OFF».
1. Connect with the welding machinewelding cables, observing the
necessary polarity. To secure the welding cable to the bayonet connector, it is
necessary to combine the tab on the cable connector with the slot bayonet
connector, push the plug with a little effort and turn it clockwise until it stops.
Before you start welding machine run:
2. Securely connect with the welding machine wire (see section 4.3.
Guidance): Connect one end of the wire to earth, and the other end of the wire
to the ground terminal, connect the product and tighten the clamping nut.
3. Securely fasten the clamp welding cable "mass" in the immediate vicinity of
the weld to reduce the resistance welding circuit.
4. Connect the power cable to the power (electrical outlet, minipower ) single-
phase AC 220 V, 50 Hz. Source power supply must be sufficient to provide the
welding power supply unit. The source must be equipped with an automatic
safety device (fuse) with the appropriate current operation. Do not connect the
product to a power supply with parameters other than those specified in
Section 3 of this manual, as it will damage the welding machine malfunction.
WARNING!
Unreliable contact will result in overheating and rapid
output BNC connectors and plugs of the system, and may
also result in inefficient operation welding machine.
WARNING!
Rated current trip a circuit breaker must be 40A.
Rated current circuit breaker must not exceed the
permissible load currents for electrical wiring home network.
CAUTION!
The electrical outlet must be grounded. The ground wire
outlet cross section must be at least 1.5 mm . If the electrical
outlet is not grounded, be sure to ground the product as
specified in 4.3. this manual.
Connect this product only to the power sockets 2P + T with
transmittance of not less than 40A.
NOTE!
Grounding of the welding machine can be accomplished in
one of two ways: to connect the grounding terminal of the unit
"Ground" or the product is connected to a grounded outlet.

5.3. WELDING
1. Clean the surface of the metal in the weld zone and the connection point
of the clip "mass" of dust, dirt, water, rust and paint.
2. Make a one-sided or two-sided V-shaped edge processing (if the
workpiece thickness of 3 mm).
3. Place the electrode in the electrode.
4. Set the desired welding current value.
The required value of the welding current is adjusted by turning the manual
knob to match the index mark on the controller with the desired value on the
graduated scale. In this case, it should be noted that the exact value of the
welding current will be displayed on the electronic display (models Mi 200md,
Mi 200da and Mi 225da). Value of the welding current is set depending on the
thickness of the weld metal and the diameter of the electrode used (see the
specifications of the electrode at its packing box): 1,6 mm - 60-90 A;
2,5 mm - 90-100 A; 3,2 mm - 110-140 A; 4,0 mm - 140-200 A,
5, 0 mm - 200-225A.
5. Touch the part to be welded.
6. To excite the arc pull the electrode from the work piece at a distance
(depending on the diameter of the electrode spacing should correspond to the
diameter of the electrode used 1-1.5) and hold it for the entire length of the
welding process (see Figure 6).
5. Turn on the power switch, turning the key «ON / OFF» to position «ON».
6. After turning the system of forced cooling products (inaudible hum
characteristic), by turning the manual control of welding current to set the
desired current value. Information on the digital display shows the set value of
welding current (models Mi 200md, Mi 200da and Mi 225da).
7. Check the status indicator light "Overheat".
8. The welding machine is ready for operation.
WARNING!
If it is lit, welding machine stays in the mode of thermal
protection, which occurred due to overloading. Let cool
product. Automatic welding machine is ready for operation
when the internal temperature decreases, the indicator light
will go off.
CAUTION!
Making any connections to the welding circuit must be
disconnected from the power supply when the product.
WARNING!
Do not use welding cables longer than 10 meters
CAUTION!
Do not use metal objects that are not part of the structure to
be welded (metal rods, tubes, strips, etc.) for replacement or
extension of welding cable with clamp "weight", as it leads to
violations of safety rules, an increase in resistance welding
circuit and accordingly, reduce the quality of weld joint.
WARNING!
Before welding, always use a protective mask welding or
special goggles with tinted glasses to protect your eyes from
strong light and ultraviolet radiation, formed by an electric
arc.
WARNING!
Do not knock the welding electrode strong surface because
it can lead to damage of the electrode and arcing difficult.

27
26
7. To stop the welding electrode take away from the work piece. The
correct direction of discharge electrode is shown in Figure 7
For a durable welded joint than the correct choice of welding current is
necessary to ensure the correct position of the electrode relative to the work
piece. The angle of inclination of the electrode should be 60-80 degrees (see
Figure 8). With too large inclination of the weld may be porous, at too small an
angle - a large amount of splash of molten metal and the arc becomes
unstable.
The length of the electrode in the welding process reduced. When the
electrode length is 15-20 mm, stop and replace the welding electrode,
electrode-clicking the handle.
Welding electrode with a protective coating layer accompanied by
formation of slag along the trajectory of movement of the electrode. To obtain a
uniform and smooth seal, as well as to avoid corrosion is formed on the seam,
it is necessary to remove the slag layer always after each pass through the
brush hammer.
After the termination of the arc on the electrode is always the peak of
plastering 1-2 mm long. When re-ignition of the arc must be dosed blow to
knock this electrode shield and the remains of slag.
Basic electrodes for DC welding (UONI 13/55, etc.) are preferably used in
cases where it is necessary to obtain high mechanical characteristics of the
weld, for example, when welding pipes, since such a coating imparts
increased viscosity of the molten pool and provides greater depth boiling
seam.
To get a quality weld such electrodes require mandatory baking. Welding is
performed by the DC reverse polarity (electrode is connected to the BNC
connector on the welding machine labeled "+").
Coated welding electrodes for alternating current (IR-3 ANO-21, etc.) can
perform a straight polarity ("-" of the electrode) and feedback ("+" on the
electrode). Polarity selection depends on the welding conditions. Reverse
polarity provides a more stable arc with low-quality electrodes heats the
workpiece less. Is mainly used for welding thin parts and to work in tight
spaces. The electrode is burned slowly. Straight polarity allows more heat to
the weld area. Is mainly used for welding the heat capacity of the massive
parts. The electrode burns faster .
WARNING!
The electrode and the slag heated to a high temperature. To
avoid burns, be careful when changing the electrode and
remove slag.
