Recommendations 1. 3.
Risk of electric shocks.
The electrical components include the electrode,
the welding circuit, the input circuit and the inter-
nal circuits, the welding wire and the metal parts in
contact with it, the wire spool and the housing for
the welding wire feed rollers. The slightest contact
with these parts may cause an electric shock or even
electrocution when the machine is switched on.
Factors increasing the risk of electric shock: Moisture
in the immediate area, working on an electrically-con-
ductive surface, inadequate earthing, poor mainte-
nance of the equipment, unsafe working methods.
Preventing risks:
Avoid any contact with live wire spools. •
In the case of water-cooled torches, inspect the •
torch at regular intervals in order to identify any
leaks; take care to prevent condensation.
Do not coil the cables around your body. •
Before replacing the electrode, ensure that it is •
no longer live.
Switch off the machine before carrying out any •
maintenance or repair operations or while it is not
in use.
Wear safety gloves, clothing, aprons and boots •
which are dry and free from holes.
Insulate the component and the earth by means •
of mats or other means of providing suf fi cient in-
sulation if the welder is required to work on metal
surfaces or structures.
This machine must be installed and earthed in ac- •
cordance with its User Manual and with national,
local and municipal codes of practice.
The return cable must be attached correctly (clean •
contact surface, cable securely fastened, as close
as possible to the area to be welded).
Do not use damaged, worn or bare (uninsulated) •
cables which are of insuf fi cient size or not prop-
erly assembled. If this is the case, they must be
replaced immediately.
The welding station must be correctly earthed. •
If the component to be welded has to be earthed, •
use a separate cable.
Use the appropriate connectors. •
Note the no-load voltage, which is limited to 80 V
r.m.s. for alternating current or 113 V for direct
current (the voltage required to strike the arc). The
maximum value for plasma cutting power sources is:
500 V.
Risk of inhaling fumes or
gases.
Welding generates fumes and gases which are
hazardous to health. Do not inhale the fumes.
Origin of the fumes and gases: Base metal, fi ller
metal, coating ( fl ux) with welding by coated electrode,
shielding gas, solvents and materials covering the
metal to be welded.
In order to prevent risks:
Use breathing apparatus, such as fi ltering masks, •
assisted-ventilation masks, inducted air masks
and disposable masks.
Avoid chlorinated solvents. •
Ensure that the components are completely dry •
before welding.
Do not work alone! •
Trap the fumes and gases at source. •
Remove paint, oil or any other surface coating. •
Risk of burns to the eyes or
the skin due to radiation.
Les rayonnements de l’arc de soudage sont susRadi-
ation from arc welding is liable to cause burns to the
eyes and the skin.
Identifying the risks: Exposure to the radiation
emitted by the arc, generating intense visible and
invisible rays (ultraviolet and infrared), re fl ection of
the rays while welding metals such as aluminium and
stainless steel, arc strike, sparks, pin-holes created
by the tip of a tungsten electrode.
In order to prevent risks:
Wear gloves or leather gauntlets to protect your •
hands and lower arms.
Wear an apron or gaiters to protect your legs, •
knees and forefoot.
Wear a mask (headband-type, hand-held or elec- •
tronic mask) or goggles fi tted with a suitable fi l-
ter.
Use safety shields to protect nearby workers. •
Tie a scarf around your neck and button the neck •
of the protective clothing.
