User manual
• never wrap the welding cables around your body,
• do not position yourself between the welding cables. and keep both welding cables on your same side;
• connect the return cable to the workpiece, as close as possible to the area to be welded,
• do not work next to, sit or lean on the source of the welding current,
• do not transport the welding power source or wire feeder while welding.
Pacemaker users should consult a doctor before using this equipment.
Exposure to electromagnetic fields during welding may have other health effects that are not yet known.
RECOMMENDATIONS FOR ASSESSING THE WELDING AREA AND EQUIPMENT
General Information
It is the user's responsibilit to install and use the arc welding equipment according to the manufacturer's instructions. If electromagnetic disturbances
are detected, it is the user's responsiblity to resolve the situation using the manufacturer's technical support. In some cases, this corrective action may
be as simple as earthing the welding circuit. In other cases, it may be necessary to construct an electromagnetic shield around the welding current
source and around the entire workpiece by setting up input filters. In any case, electromagnetic interference should be reduced until it is no longer an
inconvenience.
Assessing the welding area
Before installing arc welding equipment, the user should assess the potential electromagnetic problems in the surrounding area. The following should
be taken into account:
a) the presence of power, control, signal and telephone cables above, below and next to the arc welding equipment,
b) radio and television receivers and transmitters,
c) computers and other control equipment,
d) critical safety equipment, e.g. the protection of industrial equipment,
e) the health of nearby persons, e.g. those using of pacemakers or hearing aids,
f) the equipment used for calibrating or measuring,
g) the protection of other surrounding equipment.
The operator has to ensure that the devices and equipment used in the same area are compatible with each other. This may require further protective
measures;
h) the time of day when welding or other operations are to be carried out.
The size of the surrounding area to be taken into account will depend on the building's structure and the other activities taking place there. The
surrounding area may extend beyond the boundaries of the premises.
Assessment of the welding equipment
In addition to the assessment of the surrounding area, the arc welding equipment's assessment can be used to identify and resolve cases of
interference. It is appropriate that the assessment of any emissions should include in situ procedures as specified in Article 10 of CISPR 11. In situ
measurements can also be used to confirm the effectiveness of mitigation measures.
GUIDELINES ON HOW TO REDUCE ELECTROMAGNETIC EMISSIONS
a. Public mains power supply: Arc welding equipment should be connected to the mains power grid according to the manufacturer's recommendations.
If any interference occurs, it may be necessary to take additional precautionary measures such as filtering the mains power supply. Consider protecting
the power cables of permanently installed arc welding equipment within a metal pipe or a similar casing. The power cable should be protected along
its entire length. The shield should be connected to the welding power source to ensure that there is good electrical contact between the conduit and
the welding power source enclosure.
b. The maintenance of arc welding equipment: Arc welding equipment should be subject to routine maintenance as recommended by the
manufacturer. All access points, service openings and bonnets should be closed and properly locked when the arc welding equipment is in use.
The arc welding equipment should not be modified in any way, except for those modifications and adjustments mentioned in the manufacturer's
instructions. The spark gap of arc starters and stabilisers should be adjusted and maintained according to the manufacturer's recommendations.
c. Welding cables: Cables should be as short as possible, placed close together either near or on the ground.
d. Equipotential bonding: Consideration should be given to linking all metal objects in the surrounding area. However, metal objects connected to
the workpiece increase the risk of electric shocks to the user if they touch both these metal parts and the electrode. It is necessary to insulate the
operator from such metal objects.
e. Earthing the workpiece: In cases where the part to be welded is unearthed for electrical safety reasons or due to its size and location, such as ship
hulls or structural steel buildings, an earthed connection can reduce emissions in some cases, although not always. Care should be taken to avoid
the earthing of parts which could increase the risk of injury to users or damage to other electrical equipment. If necessary, the workpiece's connection
should be earthed directly, but in some countries where a direct connection is not allowed, the connection should be made with a suitable capacitor
chosen according to national regulations.
f. Protection and protective casing: The selective protection and encasing of other cables and equipment in the surrounding area may limit
interference problems. The safeguarding of the entire welding area may be considered for special applications.
THE TRANSPORTING AND MOVING OF THE MACHINE'S POWER SOURCE
The machine is equipped with a handle to easy transportation. Be careful not to underestimate its weight. The handle cannot be
used to hang or attach the machine on something else.
Do not use the cables or torch to move the welding power source. It should be moved in an upright position.
Do not carry or transport the power source overhead of people or objects.
Never lift a gas cylinder and the welding power source at the same time. Their transportation requirements are different.
