Electric System; Fire Prevention - Helvi COMPACT 306C Manual De Uso

Workers and their assistances must never
allow any parts of their bodies to come into
contact with metallic materials at high tempe-
ratures or which are moving (Fig. 8).
Using the arc welding and cutting equipment
requires strict respect for safety conditions
regarding electric currents. Make sure that
no metallic parts accessible to the operators
may come into direct or indirect contact with
a phase conductor or with the neutral of the
power grid.
All electrode holders and torches used must
be in good conditions. Do not coil the welding
cables around your body and never point the
torchs to other people (Fig. 9).
Make sure that no power cables from other ap-
pliances, control lines or phone cables are near
the welding generators.
Any other electric equipment in the welding
area must be in conformity with the correspon-
ding EMC regulation.
Caution: Access to the the working
area and near the welding/cutting
operation generators is forbidden to
anyone wearing pacemakers or other
such electric devices.
At least once every 6 months make sure that
all electric appliances and accessories are well
insulated. Contact your supplier for more infor-
mation on the maintenance and repair of such
equipment.

Warning: Never touch the welding
cable or the electrode and the piece
which is being welded at the same
time.

ELECTRIC SYSTEM

Any intervention on electrical and electronic
equipment must be entrusted to qualified tech-
nicians capable of performing such operations.
Prior to connecting your appliance to the power
grid, make sure that the counter, the overload
and short-circuit protection devices, the so-
ckets, the plugs and the electric system as a
whole are compatible with the maximum power
of the appliance and its voltage (please check
the information on the plate) and in conformity
with the norms and regulations in force.
The ground single-phase or three-phase con-
nection (yellow/green cable) must be protected
by a medium or high-intensity differential-resi-
dual current device (sensitivity between 1 and
30 mA).
If the cable is connected, the earth cable (when
present) must not be interrupted by the protec-
tion device against electric shock. The switch, if
present, must be at "O"; the power cable, if not
supplied, must be of the harmonized type.
Ground all metal parts near the operator, using
cables that are thicker or as thick as the wel-
ding cables.
The protection class of the appliance is IP22S,
which means it prevents:
- manual contact with internal parts in high tem-
perature, which are moving or live;
- the introduction of solid bodies with more than
12 mm of diameter;
- protection against rain with maximum inclina-
tion of 15°.

FIRE PREVENTION

The working area must be in conformity with
safety regulations. This means that fire extin-
guishers must be installed, compatible with the
type of fire which may happen.
The ceiling, the floor and the doors must be
non-flammable. All combustible material must
be moved away from the workplace (Fig. 10).
If this is not possible, cover it with a fireproof
cover.
