01/11
This machine has been designed in accordance with all relevant directives and standards. However, it may still generate
electromagnetic disturbances that can affect other systems like telecommunications (telephone, radio, and television) or
other safety systems. These disturbances can cause safety problems in the affected systems. Read and understand this
section to eliminate or reduce the amount of electromagnetic disturbance generated by this machine.

This machine has been designed to operate in an industrial area. The operator must install and operate this
equipment as described in this manual. If any electromagnetic disturbances are detected the operator must put
in place corrective actions to eliminate these disturbances with, if necessary, assistance from Lincoln Electric.
This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal
to 2227kVA at the interface point between the user’s supply and the public system. It is the responsibility of the installer or
user of the equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment is
connected only to a supply with a short circuit power Ssc greater than or equal to 2227kVA.

Before installing the machine, the operator must check the work area for any devices that may malfunction because of
electromagnetic disturbances. Consider the following.
 Input and output cables, control cables, and telephone cables that are in or adjacent to the work area and the machine.
 Radio and/or television transmitters and receivers. Computers or computer controlled equipment.
 Safety and control equipment for industrial processes. Equipment for calibration and measurement.
 Personal medical devices like pacemakers and hearing aids.
 Check the electromagnetic immunity for equipment operating in or near the work area. The operator must be sure that
all equipment in the area is compatible. This may require additional protection measures.
 The dimensions of the work area to consider will depend on the construction of the area and other activities that are
taking place.

Consider the following guidelines to reduce electromagnetic emissions from the machine.
 Connect the machine to the input supply according to this manual. If disturbances occur if may be necessary to take
additional precautions such as filtering the input supply.
 The output cables should be kept as short as possible and should be positioned together. If possible connect the work
piece to ground in order to reduce the electromagnetic emissions. The operator must check that connecting the work
piece to ground does not cause problems or unsafe operating conditions for personnel and equipment.
 Shielding of cables in the work area can reduce electromagnetic emissions. This may be necessary for special
applications.
WARNING
The Class A equipment is not intended for use in residential locations where the electrical power is provided by the public
low-voltage supply system. There can be potential difficulties in ensuring electromagnetic compatibility in those locations,
due to conducted as well as radio-frequency disturbances.

EN169 Standard.

FUMES AND GASES CAN BE DANGEROUS: Welding may produce fumes and gases hazardous to
health. Avoid breathing these fumes and gases. To avoid these dangers the operator must use enough
ventilation or exhaust to keep fumes and gases away from the breathing zone.

ARC RAYS CAN BURN: Use a shield with the proper filter and cover plates to protect your eyes from
sparks and the rays of the arc when welding or observing. Use suitable clothing made from durable
flame-resistant material to protect you skin and that of your helpers. Protect other nearby personnel with
suitable, non-flammable screening and warn them not to watch the arc nor expose themselves to the arc.

English 3 English
 WELDING SPARKS CAN CAUSE FIRE OR EXPLOSION: Remove fire hazards from the welding area
and have a fire extinguisher readily available. Welding sparks and hot materials from the welding process
can easily go through small cracks and openings to adjacent areas. Do not weld on any tanks, drums,
containers, or material until the proper steps have been taken to insure that no flammable or toxic vapors
will be present. Never operate this equipment when flammable gases, vapors or liquid combustibles are
present.
WELDED MATERIALS CAN BURN: Welding generates a large amount of heat. Hot surfaces and
materials in work area can cause serious burns. Use gloves and pliers when touching or moving
materials in the work area.

EQUIPMENT WEIGHT OVER 30kg: Move this equipment with care and with the help of another person.
Lifting may be dangerous for your physical health.

CYLINDER MAY EXPLODE IF DAMAGED: Use only compressed gas cylinders containing the correct
shielding gas for the process used and properly operating regulators designed for the gas and pressure
used. Always keep cylinders in an upright position securely chained to a fixed support. Do not move or
transport gas cylinders with the protection cap removed. Do not allow the electrode, electrode holder,
work clamp or any other electrically live part to touch a gas cylinder. Gas cylinders must be located away
from areas where they may be subjected to physical damage or the welding process including sparks and
heat sources.
