1 SAfETY PRECAUTIONS

WEldING aNd arc cuttING caN bE harmful to
yoursElf aNd othErs. the user must therefore be edu-
cated against the hazards, summarized below, deriving from
welding operations. for more detailed information, order the
manual code 3.300.758
ElEctrIc shock - may be fatal.
· Install and earth the welding machine according to
the applicable regulations.
· do not touch live electrical parts or electrodes with
bare skin, gloves or wet clothing.
· Isolate yourselves from both the earth and the workpiece.
· make sure your working position is safe.
fumEs aNd GasEs - may be hazardous to your health.
· keep your head away from fumes.
· Work in the presence of adequate ventilation, and
use ventilators around the arc to prevent gases from
forming in the work area.
arc rays - may injure the eyes and burn the skin.
· protect your eyes with welding masks fitted with fil-
tered lenses, and protect your body with appropriate
safety garments.
· protect others by installing adequate shields or curtains.
rIsk of fIrE aNd burNs
· sparks (sprays) may cause fires and burn the skin;
you should therefore make sure there are no flam-
mable materials in the area, and wear appropriate
protective garments.
NoIsE
this machine does not directly produce noise excee-
ding 80db. the plasma cutting/welding procedure
may produce noise levels beyond said limit; users
must therefore implement all precautions required by law.
pacEmakErs
· the magnetic fields created by high currents may affect the
operation of pacemakers. Wearers of vital electronic equip-
ment (pacemakers) should consult their physician before
beginning any arc welding, cutting, gouging or spot welding
operations.
EXplosIoNs
· do not weld in the vicinity of containers under pres-
sure, or in the presence of explosive dust, gases or
fumes. · all cylinders and pressure regulators used in
welding operations should be handled with care.
ElEctromaGNEtIc compatIbIlIty
this machine is manufactured in compliance with the
instructions contained in the harmonized standard
EN50199, and must be used solely for professional pur-
poses in an industrial environment. There may be poten-
tial difficulties in ensuring electromagnetic compatibility
in non-industrial environments.

NotEs: the welding machine has also been designed for
use in environments with a pollution rating of 3.
(see IEc 664).
2.3 DESCRIPTION Of PROTECTIVE DEVICES
2.3.1. Thermal protection
this machine is protected by a temperature probe, which
prevents the machine from operating if the allowable tempe-
ratures are exceeded. under these conditions the fan keeps
running and the lEd J lights.
2.3.2. Block protections
this welding machine is equipped with various safety devi-
ces that stop the machine before it can suffer damage.
In the event of a malfunction, the letter E may appear on
the display z, followed by a flashing number:
52 = start button pressed during start-up.
53 = start button pressed during thermostat reset.
