SECURITY
This section deals with the basic safety regulations when working with a semi-automatic welding machine
B SAFETY DURING WELDING
ELECTRIC SHOCK CAN KILL: Welding equipment produces high voltage. Do not touch
the welding gun or connected welding material when the device is plugged in. All elements
forming the welding current circuit can cause electric shock, therefore it should be avoided
to touch them with bare hands and through damp or damaged protective clothing. It is not
allowed to work on wet surfaces or use damaged welding cables. ATTENTION: Removal
of external covers while the device is connected to the network, as well as using the
device with removed covers is prohibited! Welding cables, ground cable, earthing clamp
and welding equipment should be kept in a good technical condition ensuring safe
operation.
ARC RAYS CAN BURN: It is forbidden to look directly at the electric arc with the naked
eyes. Always wear a mask or helmets with an appropriate filter. Protect the bystanders
with the use of non-flammable, radiation-absorbing screens. Protect the exposed parts of
the body with suitable protective clothing made of non-flammable material.
FUMES AND GASES CAN BE DANGEROUS: The welding process produces
harmful fumes and gases that are hazardous to health. Avoid breathing these
vapors and gases. The workplace should be adequately ventilated and equipped
with a ventilation exhaust. Do not weld in closed rooms. The surfaces of the
components to be welded should be free of chemical contamination, such as
degreasing substances (solvents), which decompose during welding, producing
toxic gases.
ATTENTION: Disconnect the device from the mains before carrying out maintenance and
cleaning.
SPARKS CAN CAUSE A FIRE: Welding sparks can cause fire, explosion, and
burns to bare skin. When welding, wear welding gloves and protective clothing.
Remove or contain all flammable materials and substances from the workplace.
Do not weld closed containers or tanks containing flammable liquids. Such
containers or tanks should be rinsed before welding in order to remove flammable
liquids. Do not weld in the vicinity of flammable gases, vapors or liquids. Fire
fighting equipment (blankets
5

fire extinguishers and dry powder or snow extinguishers) should be located near the
workplace in a visible and easily accessible place.
ELECTRICAL POWER: Disconnect the mains power supply before starting any work or
repairs on the device. Check welding cables regularly. If any damage to the wire or
insulation is noticed, they should be removed immediately. Welding cables must not be
crushed, touch sharp edges or hot objects.
WELDED MATERIALS CAN BURN: Never touch welded parts with unsecured body
parts. Welding gloves and tongs should always be used when touching and moving the
workpiece.
NOISE CAN DAMAGE HEARING: Noise from some processes or devices can damage
your hearing. Hearing protection should be worn in situations of increased noise level.

USING THE DEVICE
P. DISCONNECTING TO THE NETWORK
Before connecting this device to the mains, check the voltage, the number of phases and the
frequency.
The parameters of the supply voltage are given in the technical data section of this manual and on the rating plate of
the device.
Check the connections of the grounding conductors of the equipment to the mains.
Make sure that the mains supply can cover the input power demand of this device under normal operating conditions.
The fuse size and power cord parameters are given in the technical data of this manual.
The supply network should be characterized by a stable voltage. The cross-section of the power cables should not be less
than 2.5 mm.
Connect devices without power plugs according to the following tips.
Connection and replacement of the power cord and plug should be performed by a qualified electrician.
The wire in yellow and green insulation is the ground and should always be connected to the socket marked with the
earth symbol (PE), regardless of whether it is a 230 [V] power supply.
Earth symbol.
WITH PLACING ELECTRODE WIRE
1. Make sure that the rollers installed in the drive unit correspond to the type and diameter of the introduced
wire. If the roll groove differs with the diameter of the electrode wire, adjust the groove by turning or
replacing the roll. For steel wires, rollers with V-grooves should be used, and for aluminum wires with
U-grooves. Place the spool with the filler wire on the spool mounting mechanism, taking care that the wire
unwinding direction is in the direction of the wire entering the drive unit. Lock the spool against falling by
tightening the nut on the spool body.
The end of the wire wound on the spool, straighten or cut off the bent section, then file it off so that it is not
sharp.
To enable the introduction of the wire into the feeder, release the pressure of the feed rolls. Insert the end of
the wire into the guide at the rear of the feeder and guide it over the drive rolls and insert it into the socket
leading to the welding holder. Press the wire into the grooves of the drive rolls by tightening the clamp.

8. Remove the gas nozzle and unscrew the contact tip.
9. Switch on the device, unfold the handle so that it is in a straight line, then press the button on the handle until the
wire appears in the outlet (approx. 20 mm), release the button.
10. Screw on the contact tip, install the gas nozzle.
11. Adjust the contact force by turning the pressure knob. Too little pressure will cause the drive roller to slip.
Too much pressure force increases the feeding resistance and deforms the wire, which may result in cutting
it.
P. SHUT-OFF GAS
1. The cylinder with the appropriate shielding gas should be placed on the shelf of the semi-automatic machine and
secured against tipping over by securing it to the support using the enclosed safety devices. Remove the cap that
protects it and unscrew the cylinder valve for a moment to remove any contamination.
Install the regulator so that the gauges are vertical. Connect the semi-automatic machine with the
cylinder (outlet from the regulator) with a suitable hose.
Unscrew the reducer valve only before welding. Close the cylinder valve after welding.
Avoid welding in an open space or in a draft - a blast of air may disturb the shielding gas stream and
deprive the molten metal of its protection.

S. CHOOSING THE METHOD MMA
The device can be welded with coated consumables.
1. To weld with the MMA method, select "MMA" on the selection panel. Use the panel
adjustment knob to set the welding current A.
Additionally, depending on your preferences, you can select and set Hot start and Arc force. The current
value is shown on the display of the device.
Plug the welding cables into the current sockets (6 and 8) (plus and minus).
Recommended welding current, polarity, and electrode drying requirements are given by the electrode
manufacturers on their packaging.
2.
S. CHOOSING THE METHOD MIG-MAG IN MANUAL MODE
The device can be welded with the MAG method in manual mode, i.e. with manual parameter setting - just like in a traditional
semi-automatic welding machine.
1. Select MANUAL on the control panel.
The wire diameter selection remains active, you can select one of the wire diameters, but the adjustment range for each of
them is the same. So the choice of the diameter does not really matter.
2. Select the appropriate welding control method on the control panel.
3. When welding in a gas shield, insert the polarity conversion plug into the (+) socket and the mass holder into (-).
18

4. When welding FLUX with a self-shielding wire, insert the polarity conversion plug into the socket (-
), and in (+) the mass handle.
S. CHOOSING THE METHOD TIG- LIFT
In order to weld with this method it is necessary to use an additional TIG torch equipped with a shielding gas control
valve. The TIG torch should be connected to the negative (-) polarity connector and the gas hose to the gas cylinder
regulator. Connect the positive (+) polarity connector to the material to be welded using a cable with an earth clamp.

BASIC INFORMATION ABOUT WELDING
Coated electrode welding (MMA) is a process in which metal is melted and then joined by heating it with an electric
arc using a fusible metal electrode coated with a flux coating. The electric current creates an electric arc between the
electrode and the material being joined. During the welding process, the electrode coating decomposes under the
influence of temperature, forming gaseous substances which are a gas shield during welding and slag.
If the electrode moves around the weld site at the correct speed, the deposited metal forms a layer called a weld.
The welder is powered by an alternating current source and can generate alternating and direct current. The best welding characteristics are
obtained when using direct current.
Voltage and current are measured in the welding circuit. The voltage (V) is regulated by the arc length between the electrode and the
welded surface and depends on the diameter of the electrode. The current is a measure of the power in the welding circuit and is
measured in amperes (A) and is adjusted via a knob.
The setting of the welding current depends on the diameter of the electrode, the size and thickness of the workpiece
and the welding position. When welding materials of the same thickness, a smaller electrode and a lower welding
current are used for materials with a small surface area than for larger surfaces. A thin metal requires less current,
and a smaller electrode requires less voltage.
It is recommended to weld when working in a horizontal and vertical position. However, when we are forced to weld in
a vertical or overhead position, it is worth setting the amperage lower than when working horizontally. The best welds
are obtained by keeping the arc short, smooth movement of the electrode and driving the electrode down at a constant
speed during melting. More detailed welding procedures are presented later in these operating instructions.
ELECTRODES WELDING IN PRACTICE
Nobody can learn to weld by reading manuals, guides, or other literature on the subject. The ability to weld correctly
can only be acquired through practice. The information contained in the attached manual is intended to help
inexperienced people understand the principles of welding with coated electrodes and facilitate the start of learning.
For more information on welding, an in-depth literature is available.
The knowledge of the welding operator must go beyond the information about the arc itself. The user of the welder
must know how to control the arc, which requires knowledge of the welding circuit and the device that supplies the
current during welding. The welding cable starts at the welding torch where the electrode is mounted and ends at the
connector where the cable is attached to the welding machine. The current flows through the welding cable to the
electrode holder and then through the electric arc. On the other side of the working arc, the current flows through the
base metal to the ground conductor, then back to the device. The system must be closed. The mass holder must be
firmly mounted on the cleaned base metal. Metal should be cleaned of paint, rust, etc. it is necessary to obtain good
current flow. Connect the ground cable as close as possible to the welding point. Avoid closing the welding circuit
through hinges, bearings, electrical systems and other such objects that may impede the flow of current in the system.
