RISKS RELATED TO WELDING AND CUTTING PROCESSES
INTRODUCTION AND OVERVIEW
The most common arc welding processes are:
1. “MMA”;
2. “TIG”;
3. “MIG”;
The welding machines consist of two types, tran-
sformers or inverters (with or without polarity
the second allows for a large range of adjustments.
ACCESSORIES
According to the model, the unit can be equipped
with:
• “PM” – earth clamp with cable;
• “PPE” – electrode holder with cable;
• “CP_EURO” – polarity connector for mig torch;
• “T_EURO” – Mig torch with Euro connector;
• “T_TIG” – TIG torch;
• Hand Mask or helmet,
• Gas tube,
• Gas reducer,
• Wheel kit,
• Hammer Brush.
If provided, “PPE” or “CP_EURO” or “T_TIG” and
“PM” can be connected in:
• “PD” – direct polarity that is “PPE” or “CP_
EURO” or “T_TIG” to the negative pole (-) and
“PM” to the positive pole (+);
• “PI” – reverse polarity that is “PPE” or “CP_
EURO” or “T_TIG” to the positive pole (+) and
“PM” to the negative pole (-).
“MMA”PROCESS
Manual metal arc welding (MMA or MMAW), also
shielded arc welding or stick welding, is a process
coated metal rod and the work piece. Both the rod
and the surface of the work piece melt to create a
weld.
The inverter welders have the following automatic
features:
“HOT START” is a feature that pumps up the am-
perage for a short time when you start the arc. Hi-
gher amperage helps to start the arc easier without
sticking the electrode to the base metal.
“ARC FORCE” compensates for the voltage drop
by increasing the amperage. Increased amperage
ensures that the heat stays the same and that the
electrode will not stick to the base metal.
“ANTI STICK” is a feature that will take action
when the electrode sticks to the base metal. It will
detect the short circuit and automatically cut the
current. This prevents the electrode from turning
red-hot and the welding machine from overloading.

“TIG” PROCESS
In TIG welding the heat is produced by the electric
arc between a nonconsumable electrode (tung-
an inert gas (usually argon: Ar 99.5). The welding
MIG welding is an arc welding process that uses a
continuous solid wire electrode.
Welding “MIG” is distinguished in:
• “MIG GAS”: the material used is a metal wire and
the shielding gases are generally CO2, Argon or
CO2+Argon.
• “MIG NO-GAS”: the wire used in this process
contains already the dioxidiser, so shielding gases
is not required.
For the welders with output polarity connection ple-
ase connect the “CP_EURO” and “PM” in:
• “PI”, for “MIG GAS” welding;
• “PD”, for “MIG NO-GAS”welding.
The inverter welders may have the following auto-
matic features:
• “MIG PULSE” This mode is generally used for
welding stainless steel and aluminum. It combines
the advantages of other forms of transfer while mi-
nimising their disadvantages. The material is tran-
sferred in a controlled droplet form. The pulses cre-
ate spatter-free welds and a lower heat input allows
using this method on thinner materials.
MAINTENANCE
Repairs must be carried out by our authorised Ser-
vice Centres, or directly by the Manufacturer throu-
gh its own Customer Service.
ELECTROMAGNETIC COMPATIBILITY
The device may generate electromagnetic distur-
bances in telecommunications systems (telephone,
radio, television) or control and security systems.
Read the following instructions to eliminate or mi-
nimize the interferences. In order to meet the IEC
61000-3-11 requisite (Flicker), we recommend the
connection of the welder to the supply network in-
terface which has a lower impedance of Zmax =
0.24ohm. The device does not fall within the requi-
sites of IEC/EN 61000-3-12 standard. If it is con-
nected to a public power supply network, it is the
installer’s responsibility to verify that the welding
machine itself is suitable for connecting to it (if ne-
cessary, consult the distribution network company).
The user is responsible for installing and using the
arc welding equipment according to the manufactu-
rer’s instructions. If electromagnetic disturbances
are detected, then it should be the user’s respon-
sability to solve the situation with the technical
assistance of the manufacturer. Do not modify the
device without the manufacturer’s approval.
Working area control in order to prevent the
electromagnetic interferences:
Before installing the device, the user must check
the working area to detect the existence of services
which could malfunction in the event of electroma-
gnetic interference.
The following services should be taken into ac-
count:
1. Power cables, control cables, transmission and
telephone system cables nearby the generator;
2. Radio or television transmitters and receivers;
3. Computer or control devices;
4. Safety equipment and industrial process control;
5. Individual medical equipment of users operating
6. Calibration and measurement equipment.
Check the electromagnetic immunity level of the
equipment operating in the area. The user must
ensure that the other devices are electromagneti-
cally compatible. This operation may require the in-
troduction of additional protective measures. Some
problems can be solved by carrying out welding
and cutting operations when other equipment are
not in use. The size of the area to be considered
depends on the structure of the building and what
activities are taking place.
Supply system
El equipo de soldadura o de corte debe conectar-
se a la red siguiendo las recomendaciones del
fabricante. En caso de interferencias, puede ser
necesario tomar precauciones adicionales, como
de que el equipo de soldadura esté instalado de
forma permanente, se puede considerar el blindaje
metálico de los cables de alimentación. El blindaje
debe conectarse al generador para que haya un
buen contacto eléctrico entre éste y la envolvente
del propio generador.
Maintenance
The equipment must undergo regular maintenan-
ce, according to the manufacturer’s instructions.
The casing and any access within it must be pro-
perly closed during the welding and cutting. The
part thereof, except amendments provided by the
manufacturer and authorized and executed by per-
sons authorized by the manufacturer. In particular,
the arc distance from the work piece and the stabi-
lization devices, must be adjusted and maintained
according to manufacturer’s recommendations.
Welding cables
The welding cables should be kept as short as
possible and should be positioned close together,
Earthing of the work piece
Grounding the workpiece can, in some cases, re-
duce electromagnetic emissions. The user must
pay attention to prevent the earthing of the piece
from being a source of danger to people and da-
mage to the equipment. Where necessary, earthing
must be done with a direct connection between the
piece and earth, while in countries where this is not
permitted, the connection must be done using a ca-
pacitor in accordance with the country’s legislation.
Screening and shielding
Shielding of cables and equipment in the working
area can reduce interference. Shielding of the enti-
re welding or cutting installation may be considered
for special applications.
The welding machine is class A and is primarily in-
tended for industrial use. Use in other environmen-
-
gnetic compatibility. The correct use of the welding
machine is users responsibility.
