Safety Warnings - Deca D-mig 760 TD Bedienungsanleitung

Manutenzione
Spegni la saldatrice ed estrai la spina dalla presa d'alimentazione prima di effettuare
operazioni di manutenzione.
Manutenzione ordinaria effettuabile dall'operatore periodicamente in funzione dell'uso.
• Controlla i collegamenti del tubo gas, del cavo torcia e del cavo massa. • Pulisci con
una spazzola di ferro l'ugello portacorrente ed il diffusore gas. Sostituiscili se sono
usurati. • Pulisci la saldatrice all'esterno con un panno umido.
Ad ogni sostituzione della bobina di filo:
• Controlla l'allineamento, la pulizia e lo stato di usura del rullino trainafilo Fig.10. •
Asporta la polvere metallica che si deposita sul meccanismo trainafilo. • Pulisci la guaina
guidafilo con solventi anidri e sgrassanti ed asciuga con aria compressa. • Controlla
l'usura delle Etichette di avvertenza. • Sostituisci le parti usurate.
Manutenzione straordinaria effettuabile da personale esperto o qualificato in ambito
elettromeccanico periodicamente, in funzione dell'uso. (Applicare la norma EN 60974-4)
• Ispeziona l'interno della saldatrice e rimuovi la polvere depositata sulle parti elettriche
(usa aria compressa) e sulle schede elettroniche (usa una spazzola molto morbida o dei
prodotti appropriati).
• Verifica che le connessioni elettriche siano ben serrate e che i cablaggi non abbiano
l'isolante danneggiato.
Instruction Manual
Read this instruction manual carefully before using the welding machine.
MIG/MAG continuous wire arc-welding machines, referred to in this manual as "welding
machines", are designed for industrial and professional use.
Make sure that the welding machine is installed and repaired only by qualified persons or
experts, in compliance with the law and with the national regulations.
Make sure that the operator is trained in the use and risks connected to the arc-welding
processs and in the necessary measures of protection and emergency procedures.
Detailed information can be found in the "Installation and use of arc-welding equipment"
brochure: IEC or CLC/TS 62081.

Safety warnings

„ Make sure that the power socket to which the welding machine is connected is protected
by suitable safety devices (automatic switch) and that it is grounded.Make sure that the
plug and power cable are in good condition.
„ Before plugging into the power socket, make sure that the welding machine is switched
off.
„ Switch the welding machine off and pull the plug out of the power socket as soon as
you have finished working.
„ Switch the welding machine off and pull the plug out of the power socket before:
connecting the welding cables, installing the continuous wire, replacing any parts in the
torch or wire feeder, carrying out maintenance operations, or moving it (use the carrying
handle on the welding machine).
„ Do not touch any electrified parts with bare skin or wet clothing. Insulate yourself
from the electrode, the piece to be welded and any grounded accessible metal parts.
Use gloves, footwear and clothing designed for this purpose and dry, non-flammable
insulating mats.
„ Use the welding machine in a dry, ventilated space. Do not expose the welding machine
to rain or direct sunshine.
„ Use the welding machine only if all panels and guards are in place and mounted
correctly.
„ Do not use the welding machine if it has been dropped or struck, as it may not be safe.
Have it checked by a qualified person or an expert.
„ Eliminate any welding fumes through appropriate natural ventilation or using a smoke
exhauster. A systematic approach must be used to assess the limits of exposure
to welding fumes, depending on their composition, concentration and the length of
exposure.
„ Do not weld materials that have been cleaned with chloride solvents or that have been
near such substances.
„ Use a welding mask with adiactinic glass suited for welding. Replace the mask if
damaged; it may let in radiation.
„ Wear fireproof gloves, footwear and clothing to protect the skin from the rays produced
by the welding arc and from sparks. Do not wear greasy garments as a spark could set
fire to them. Use protective screens to protect people nearby.
„ Do not allow bare skin to come into contact with hot metal parts, such as the torch,
electrode holder grippers, electrode stubs, or freshly welded pieces.
„ Metal-working gives off sparks and splinters. Wear safety goggles with protective side
eye guards.
„ Welding sparks can trigger fires.
„ Do not weld or cut anywhere near inflammable materials, gasses or vapours.

EN
„ Do not weld or cut containers, cylinders, tanks or piping unless a qualified technician
or expert has checked that it is possible to do so, or has made the appropriate
preparations.
„ Never direct the torch towards yourself, others or metal parts; the continuous wire could
make holes or cause short circuits.
„ Switch off the welding machine and pull the plug out of the power socket before carrying
out any manual operations on the moving parts of the wire feeder.
EMF Electromagnetic Fields
Welding current creates electromagnetic fields (EMF) near the 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 having such aids should 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.
„ 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 9 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 in conditions of risk
„ If welding needs to be done 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 welding 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 welding machine for purposes other than those described, for example
to thaw frozen water pipes.
„ Place the welding machine and wire feeder 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 welding sparks.
„ Do not lift the welding machine. No lifting devices are fitted on the machine.
„ Do not work with the wire feeder hanging from your body using straps or any other
device.
„ Do not use cables with damaged insulation or loose connections.
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).
This manual refers to a range of welding machines that differ in some of their
characteristics. Identify your model in Fig. 1.
