an explosion.
F. F. Avoid direct contact of the skin or wet clothes with
live metal parts. Wear dry or insulation protective equi-
pment.
Residual current is present in the inverter after work.
Do not hold an unfixed workpiece in your hands.
Do not touch the workpiece close to the weld since
the weld is very hot. Let it cool down. Do not touch
the electrodes directly after use. Let them cool down.
In the proximity of the welding equipment, any persons
having a pacemaker and a cardioverter defibrillator
must not be present. Do not use the welding equip-
ment after consuming drugs, alcohol, medicaments or
if tired.
Prevention of Fire and Explosion
Hot slag parts and sparks may cause fire.
Protect flammable objects or cover them by inflamma-
ble materials where applicable. Flammable materials
include: wood, sawdust, clothes, paints and solvents,
petrol, fuel oil, natural gas, acetylene, propane and si-
milar flammable substances.
A. Do not weld vessels or piping where flammable ma-
terials (solid, liquid or gaseous) have been stored. Do
not weld materials that have been cleaned by cleaning
products containing chlorine (or similar substances)
since arc-induced vapours may produce toxic gases or
may result in an explosion.
B. As a fire prevention, prepare appropriate fire extin-
guishing devices, e.g. fire extinguishers, water, sand,
in the proximity of the welding equipment.
C. Do not perform welding and cutting on closed ve-
ssels and pipes.
Risk of Poisoning
A. The workspace must be adequately ventilated! Ga-
ses and smoke released during welding are harmful if
being inhaled for a long time. Therefore, adhere to the
following regulations:
B. Ensure adequate natural or forced ventilation in the
workspace.
C. Use a protective breathing apparatus and ensure
fresh air inlet in all places with insufficient supply of air.
D. Attention! Leaking gas is a source of risk. Protective
gases, e.g. argon, are heavier then air and may push
the air out in narrow spaces.
EAs a basic rule, a welder working in narrow spaces
(e.g. boilers, trenches) must be safeguarded by ano-
ther worker from the outside.
F. When working with lead, zinc, cadmium, beryllium,or
galvanized and painted materials, forced ventilation is
necessary. The welder must wear a respirator.
G. Insufficient ventilation and related symptoms of
poisoning are manifested by irritation of eyes, nose
and throat. In that case interrupt your work and ven-
tilate the workplace properly. If the problems persist,
stop welding.
H. Do not weld close to areas where painting or degre-
asing is carried out. In such areas, vapours containing
chlorinated hydrocarbons may be present in the air
(due to such work processes); under high temperatu-
res and electric arc radiation, a highly toxic phosgene
gas is produced.
! The welding equipment is provided with a protective
circuit against overload or against excessive electric
current and heat. If the voltage and output current
levels including equipment temperature exceed the
safety regulations, the welding equipment is automati-
cally switched off. Since higher values of the aforesaid
may have caused damages to the equipment.
If the welding time exceeds the allowed period of the
particular working mode, the welding equipment is
switched off for its own protection. Since the equipment
is overheated, the indicator light is red. Under such
conditions, it is forbidden to pull the plug out because
the equipment must be cooled. When the indicator li-
ght is extinguished, the temperature has returned to its
normal value and you may continue welding.
If unused, store the equipment on a safe dry place
away from children.
- Use protective equipment against noise,
dust and vibrations !!!

DESCRIPTION (A)
The inverter is a rectifier provided with the most advan-
ced technology of inversion.
The development of a welding converter is considered
a revolution in welding industry.
The welding energy source may penetrate a thicker,
more concentrated and more stable arc. When the ad-
hesiveness and the workspace decrease, its reaction
is much faster. It means that this is a welding equip-
ment with various dynamic features, which may be set
to a larger or a smaller arc.
The welding equipment is characterized as follows:
It is efficient, energy-saving and compact. It provides
a stable arc, well-welded joints, high no-load voltage,
good compensation force capacity and is multipurpo-
se. It may weld stainless steel, alloy steel, carbon ste-
el, coper, aluminium and other non-ferrous metals. It
may work with electrodes having different properties
and materials, including acidic, alkaline and granular.
It may be used in high altitudes, different atmospheric
pressures, indoors or outdoors. When compared with
classic welding equipment, it is compact, with small
volume and weight, and its installation and operation
are easy.
Manual metal arc (MMA) means manual welding with
a coated electrode. This method is especially used du-
ring assembly welding due to the equipment mobility.
Inverter - a DC welding source determined for manu-
al welding by a coated electrode. The source utilizes
modern knowledge from power and control electronic
fields. This results in high performance with low wei-
ght and good welding properties. It is suitable for use
during assembly and craft work. The current range
enables use of electrodes starting from diameter of 1.6
