
Never directly touch live parts. After use, care-
fully replace the torch or the electrode holding
grippers, avoiding contact with the parts con-
nected to earth.
SAFETY REGARDING WELDING FUMES
AND GAS

Carry out purification of the work
area, from gas and fumes mitted du-
ring the welding, especially when welding is
carried out in an enclosed space.

Place the welding system in a well-aired place.

Remove any traces of varnish that cover the parts
to be welded, in order to avoid toxic gases being
released. Always air the work area.

Do not weld in places where gas leaks are
suspected or close to internal combustion
engines.

Keep the welding equipment away from baths for
the removal of grease where vapours of tri-
chlorethylene or other chlorine containing hyd-
rocarbons are used as solvents, as the welding
arc and the ultraviolet radiation produced by it
react with such vapours to form phosgene,
a highly toxic gas.
PROTECTION FROM
BURNS AND NOISE

Never use broken or defective
protection masks.

Do not look at the welding arc without a suitable
protective shield or helmet.

Protect your eyes with a special screen fitted with
adiactinic glass (protection grade 9-14 EN 169).

Immediately replace unsuitable adiactinic glass.

Place transparent glass in front of the adiactinic
glass to protect it.

Do not trigger off the welding arc before you are
sure that all nearby people are equipped with
suitable protection.

Pay attention that the eyes of nearby persons are
not damaged by the ultraviolet rays produced by the
welding arc.

Always use protective overalls, splinter-proof
glasses and gloves.

Wear protective earphones or earplugs.

Wear leather gloves in order to avoid burns and
abrasions while manipulating the pieces.
AVOIDANCE OF FLAMES AND EXPLO-
SIONS

Remove all combustibles from the
workplace.
RADIATION,

Do not weld close to inflammable materials or li-
quids, or in environ ments saturated with explo-
sive gasses

Do not wear clothing impregnated with oil and
grease, as sparks can trigger off fame's.

Do not weld on recipients that have contained
inflammable substances, or on materials that can
generate toxic and inflammable vapours when
heated.

Do not weld a recipient without first determin-
ing what it has contained. Even small traces of an
inflammable gas or liquid can cause an explo-
sion.

Never use oxygen to degas a container.

Avoid gas-brazing with wide cavities that have
not been properly degassed.

Keep a fire extinguisher close to the workplace.

Never use oxygen in a welding torch; use only
inert gases or mixtures of these.
RISKS DUE TO ELECTROMAGNETIC
FIELDS

The magnetic field generated by
the machine can be dangerous to
people fitted with pace-makers, hearing aids and
similar equipment. Such people must consult
their doctor before going near a machine in
operation.

Do not go near a machine in operation with
watches, magnetic data supports and timers etc.
These articles may suffer irreparable damage due
to the magnetic field.

This equipment complies with the set protection
requirements and directives on electromag-netic
compatibility (EMC). Welding machines in terms
of interference suppression are determined for
industrial space - classification according to EN
55011 (CISPR - 11) group 2, inclusion class A. Is
assumed that their wide use in all industrial area,
but it is not for using at home! In particu-lar, it
complies with -the technical prescriptions of the
EN 60974-10 standard and is foreseen to be used
in all industrial spaces and not in spaces for
domestic use. If electromagnetic disturban-ces
should occur, it is the user's responsibility to
resolve the situation with the technical assistan-
ce of the producer. In some cases the remedy is
schormare the welder and introduce suitable
filters into the supply line.
WARNING: This inclusion class A is not made for using
in residential premises where is electrical energy
supplied by low-voltage system. Here can be some
problems with
