welding circuits and the welder. Electromagnetic fields may
interfere with medical prostheses such as pacemakers.
Suitable and sufficient measures should be implemented
to protect those operators having such aids. For instance,
they should not be allowed to enter that area where welding
equipment is used. Any operator
consult their doctor before coming close to an area where
welding equipment is used.
This device meets the specific requirements of the product
technical standard and is intended for professional use in an
industrial environment only. Compliance to expected limits
for human exposure to electromagnetic fields at home is not
ensured.
Follow these strategies to minimise exposure to electromagnetic
fields (EMF):
„ Do not place your body between the welding cables. Both
welding cables should be on the same side of your body.
„ Twist both welding cables together and secure them with tape
when possible.
„ Do not wrap the welding cables around your body.
„ Connect the earth cable to the workpiece as close as possible
to the area to be welded.
„ Do not work with the welder hanging from your body.
„ Keep your head and trunk as far as possible from the welding
circuit. Do not work close to the welder, or seated or leaning
on it. Minimum distance: Fig 11 Da = cm 50; Db = cm.20
Class A equipment
This equipment has been designed to be used in professional
and industrial environments.
If this equipment is used in domestic environments and those
directly connected to a low voltage power supply network
which supplies buildings used for domestic purposes, it may be
difficult to ensure compliance to electromagnetic compatibility
as the result of conducted or radiated disturbances.
Welding (cutting) in conditions of risk
„ IIf you are required to work in conditions of risk (electric
discharges, suffocation, the presence of inflammable or
explosive materials), make sure that an authorised expert
evaluates the conditions beforehand. Make sure that trained
people are present who can intervene in the event of an
emergency. Use the protective equipment described in 5.10;
A.7; A.9 of the IEC or CLC/TS 62081 technical specification.
„ If you are required to work in a position raised above ground
level, always use a safety platform.
„ If more than one machine has to be used on the same piece,
or in any case on pieces connected electrically, the sum of the
no-load voltages on the electrode holders or on the torches
may exceed the safety levels. Make sure that an authorised
expert evaluates the conditions beforehand to see if such risk
exists and adopt the protective measures described in 5.9 of
the IEC or CLC/TS 62081 technical specification if required.
Additional warnings
„ Do not use the machine for purposes other than those
described, for example to thaw frozen water pipes.
„ Place the machine on a flat stable surface, and make sure
that it cannot move. It must be positioned in such a way as
to allow it to be controlled during use but without the risk of
being covered with sparks.
„ Do not lift the machine. No lifting devices are fitted on the
machine.
„ Do not use cables with damaged insulation or loose
connections.

having such aids should
„ Connections to the mains must be made by expert or qualified
personnel.
„ Make sure that the machine is switched off and disconnected
from mains before carrying out this procedure.
„ Make sure that the power socket that the machine is plugged
into is protected by safety devices (fuses or automatic switch)
and grounded.
„ The device must be connected only to a supply system, with
an earthed 'neutral' lead.
Recommendations for use
„ Only use an extension lead when absolutely necessary and
providing it has an equal or larger section to the power cable
and is fitted with a grounding conductor.
„ Do not block the machine air intakes. Do not store the machine in containers or on shelving that does not guarantee suitable
ventilation.
„ Do not use the machine in any environment in the presence
of gas, vapours, conductive powders (e.g. iron shavings),
brackish air, caustic fumes or other agents that could damage the metal parts and electrical insulation.
The electric parts of the machine have been treated with
L
protective resins. When used for the first time, smoke may
be noticed; this is caused by the resin drying out completely.
The smoke should only last for a few minutes.
Description of the welding machine
The welding machine is a current generator for continuous wire
welding, commonly known as MIG / MAG, suited to welding
carbon or light alloy steels, stainless steel and aluminium using protective gas.
The electrical characteristic of the transformer is flat (constant
voltage).
The welding machine is a current transformer for manual arc
welding using MMA coated electrodes and TIG with a torch
that strikes the arc on contact.
The delivered current is direct.
The electrical characteristic of the transformer is of the falling
type.
The welding machine is built using electronic INVERTER
technology.
