Ensure that the power supply network can provide coverage of the input power demand for this
device under normal operating conditions. The fuse size, the parameters of the power cord are
given in the technical data and on the rating plate. Connection and replacement of the power
cord and plug should be made by a qualified electrician.
Remove all flammable materials from the welding area.
Use appropriate protective clothing for welding: gloves, apron, work boots, mask or visor with
appropriate certificates.
DEVICE CONNECTION FOR THE MIG / MAG METHOD
To extend the service life and ensure reliable operation of the device, observe the following rules:
The device should be placed in a well-ventilated room with free air circulation.
Do not place the device on wet ground.
Use an electrode wire with diameter and spool weight in accordance with the manufacturer's
instructions (D200, max. 15 kg). Check the technical condition of the device and welding cables on
an ongoing basis.
Welding wire spool assembly:
The device is equipped with professional wire feeder, it has 4 rolls feeder enabling work with 2
handles max 4mb when welding with steel wire and with 3mb when welding with aluminum alloy
wire, The welding wire holder allows the installation of reels with a diameter of 300mm-15kg.
5kg wire coil 15kg wire coil
Lift the side cover of the semi-automatic housing.
Ensure that the rollers fitted in the drive unit match the type and diameter of wire used. Rolls
should be used for steel wires with "V" shaped grooves, while for aluminum wires with "U" type
grooves.
Apply welding wire spools to the spool clamping mechanism, paying attention that the unwinding
direction of the wire is consistent with the direction of the wire's entry into the drive unit. Lock
the spools before slipping by tightening the nut on the spool mounting body.
The end of the wire should be straightened or cut off a bent section.
To feed wire into the feeder, release the pressure of the feed rollers.

USER MANUAL

Insert the end of the wire into the guide located at the back of the feeder and route it over the
drive roller by inserting it into the welding gun stub.
Tighten the wire in the drive roller groove and tighten.
Remove the gas nozzle from the burner and unscrew the contact tip.
Turn the device on.
Unwind the welding gun cable so that it is straight. ATTENTION! Do not drive the
welding torch ends towards the face or other people.
Press the welding button on the welding gun and hold it until the wire appears behind the torch.
When the end of the welding wire passes through the connector in the torch, release the button
approx. 5 cm and replace the contact tip and gas nozzle.
Adjust the clamping force by turning the knob, clockwise-increases the clamping force, to the left-
decreases the clamping force. Too low clamping force will cause the drive roller to slip. Too much
pressure increases the feed resistance and deforms the wire.
We recommend placing the wire into the welding gun with the valve on the shielding gas cylinder
closed. This will reduce its unnecessary losses.
Installation of shielding gas cylinders:
A cylinder with a suitable shielding gas must always be properly secured against falling over. If
possible, attach to an approved welding carriage with the MIG / MAG device. The trolley is not
standard equipment of the set.
Connect the semi-automatic machine to the cylinder with a suitable hose.
Unscrew the regulator valve before starting to weld. Always close the cylinder valve after welding.

MIG/MAG welding process
Arc welding in gas shields (marked MIG / MAG) is one of the most commonly used processes in the
production of welded structures. The abbreviation MAG (Metal Active Gas) includes in its
description types of active protective gases. The abbreviation MIG (Metal Inert Gas) refers to inert
gas shields. The semi-automatic welding process involves fusing the edges of the work piece and
the consumable electrode material with the heat of an electric arc glowing between the electrode
in the form of a solid wire and the welded part, in an inert or active gas shield.
The main protective gases used for MIG welding are inert gases such as argon, helium and MAG
active gases: CO2, H2, O2, N2 and NO, used separately or as additives to argon or helium.
The fusible electrode is in the form of a solid wire, usually 0.6 1.2 mm in diameter, and is fed in mm,
and is fed in m / min upwards. Welding torches can be cooled by liquid or shielding gas. Welding is
carried out mainly with direct current with positive polarity, as semiautomatic, mechanized
welding, direct current with positive polarity, as semi-automatic, mechanized, automatic or robotic
welding using specialized equipment. The shield of the welding arc glowing between the

USER MANUAL
8
consumable electrode and the material being welded ensures the formation of the weld under
very favorable thermal and chemical conditions. This type of welding can be used to make high-
quality joints of all metals that can be joined by arc welding. These include: carbon and low alloy
steels as well as corrosion resistant steels. Welding can be carried out in workshop and field
conditions in all positions.
SINGLE PULSE MODE
MIG PULSE is an advanced form of welding that uses the best of the forms of the transfer of molten
electrode material to the work piece. Unlike short circuits, pulse welding does not produce spatter
and there is a risk of cold "leakage". Welding positions in the pulse are not limited because they are
derived from globular or spray forms, and their use is definitely more efficient. By cooling the spray
arc process, pulsed MIG is able to extend the welding range, and smaller heat input does not cause
a problem with burning thin materials. MIG PULSE is one of the best welding processes for a wide
range of applications and types of metal.
DOUBLE PULSE MODE
Welding with the MIG / MAG method with double pulse we get a high level of face appearance
(husk effect). In addition, the use of automatic wire feed affects welding performance. The MIG /
MAG method with double pulse allows the regulation of current pulsation (pulse balance) and
adjustment of the wire feed speed. Thanks to this, we improve the appearance of the weld. When
MIG / MAG welding with double pulse, current pulses occur in two ranges. The sequential system of
our devices automatically combines two levels of pulses.
The benefits of using the MIG MAG method with double pulse are:
1. MIG / MAG double pulse welding is faster than TIG welding.
2. MIG / MAG double pulse welding achieves high aesthetics like the TIG method.
3. MIG / MAG double pulse welding results in less deformation than TIG.

B. CHOICE OF WELDING METHOD
This page allows you to select welding methods as below:
Synergy, MIG, LIFT-TIG, MMA
Turn the red knob of the font panel to select the welding mode then press for confirmation.
SYNERGY - synergic settings. The user selects the basic welding parameters such as the type of
material, thickness of the material to be welded, diameter of the welding wire. Other parameters of
the device are selected automatically using the database of uploaded programs.
MIG mode - welding using individual user settings. The system suggests the selection of key welding
parameters, indicating the thickness of the welded material when adjusting them. This information
suggests to the user that the settings are correct.
LIFT-TIG - TIG lift mode (ignition of the arc by rubbing) - welding with a tungsten electrode in an inert
gas shield.
MMA MODE - welding with coated electrode. In addition to welding current adjustment, the user can
additionally set ARC-FORCE, HOT START and enable or disable the VRD protection system.
ARC FORCE - Stabilizes the arc regardless of fluctuations in its length, reduces the amount of spatter.
HOT-START - a function that makes welding easier. When the arc strikes, the welding current is
temporarily increased to heat up the material and electrode at the point of contact, and to properly
shape the penetration and weld face at the initial stage of welding.

USER MANUAL
12
VRD - the device has a VRD (Voltage Reduction Device) system, which for welding mode MMA with
electrodes reduces the open circuit voltage, which significantly increases the user's safety. In special
cases of using electrodes with high arc ignition current, problems with its initiation may occur.
C. Synergy function (MIG/MAG )
In the SYNERGY mode, the user only selects the basic welding parameters such as the type of material, the
thickness of the material to be welded, and the diameter of the welding wire (0.8mm, 1.0mm and 1.2mm
available). Other parameters of the device are selected automatically using the database of uploaded
programs.
The SYNERGY mode only allows continuous welding, it has no possibility to adjust the PULS and dual
PULS settings.
You can manually correct the synergy settings.
NOTE: If the material type and thickness settings are changed, the system will return with the
remaining parameters to the factory default values.
Step 1-Choice of material
The user selects the welded material (and
welding wire) from the list of alloys available in
the program.
Step 2-Selecting the thickness of the work
piece
The user chooses the thickness of the welded
material. The device automatically selects the
intensity on this basis welding current, arc
voltage and feeder speed.

USER MANUAL

Step 3 Selecting the welding wire diameter
You choose the welding wire diameter you plan
to use.
ATTENTION!
The device automatically reduces or increases
its maximum power depending on the wire
diameter.
Step 4 Selecting the welding wire diameter
You choose the welding wire diameter you
plan to use.
ATTENTION!
The device automatically reduces or increases
its maximum power depending on the wire
diameter.
Step 5 Selecting the welding wire diameter
You choose the welding wire diameter you
plan to use.
ATTENTION!
The device automatically reduces or increases
its maximum power depending on the wire
diameter.
According to the programmed welding parameters, the welding wire diameters selected by the
user directly influence the welding current and voltage, and wire feeder speed. For example,
choosing a 0.8mm wire will automatically limit the maximum welding current to e.g. 140A,
choosing a 1.0mm wire will allow welding 200A current. These actions are aimed at optimizing
the welding process and avoiding problems associated with burning the wire too quickly just
after the contact tip in a situation where it is no longer possible to increase the feeder speed.
The inability to set the maximum welding current is not a software error and results from the welding
wire diameter selected.

USER MANUAL

D.MIG/MAG OPERATION
In MIG welding mode, the user sets all welding parameters one after the other. The system
suggests the selection of optimal welding parameters by indicating at their adjustment thickness of
the welded material (see table - setting the wire feeder speed). This information suggests to the
user that the settings are correct. Depending on the welding style (forced positions, fast welding
with higher current or slower current with lower intensity), these settings may require a slight
adjustment by the user.

Choice of welded material (and wire)
From the list of alloys available in program.
Setting the wire feeder speed ATTENTION!
It will show automatically the estimated
thickness of the welded material in order to
select the optimal welding parameter.
Adjusting the arc voltage
Increasing or decreasing this value will lengthen
or shorten the arc length.
Inductance regulation
Properly selected welding inductance reduces
the amount of spatter. It depends on the wire
diameter welding, shielding gas used, current
and welding position. Reducing the inductance
makes the arc more stable and concentrated,
while increasing contributes to the formation of
a more fluid pool and reduces the amount of
spatter. Properly selected, it is characterized by
a stable arc, even transfer of liquid metal
droplets, maintaining a constant weld pool size
and characteristic repetitive sound without
splashes and explosions.

E. MIG / MAG WELDING WITH PULSE
In order to start welding in MIG / MAG PULS mode, the settings should be made as in the
previous chapter. Additional welding parameters in pulse welding mode are presented in the
following tables:
Welding current selection2
The pulse current function is mainly used when
welding thin elements, low melting metals, e.g.
lead, or welding in forced positions. Other
advantages of pulsating current welding are the
smaller heat affected zone, greater welding arc
stability,
Pulse frequency adjustment
Changing this parameter extends or shortens the
welding arc.
ATTENTION!
The pulse frequency is automatically selected
based on the other welding parameters, there is
no need to manually correct it.
Pulse cycle setting
Adjusting this parameter causes increasing or
reducing the amount of spatter during welding.
ATTENTION!
The pulse cycle value is automatically selected based
on the other welding parameters, there is no need to
manually correct it.
