7. Welding operation
7.1 Operation procedure
WARNING
Provide sufficient ventilation or
wear breathing equipment.
Toxic fumes and gases
generated during welding can
be hazardous.
Welding in a confined area
can cause suffocation due to
oxygen deficiency.
Inhalation of gases and
fumes generated during
welding can damage health.
WARNING
Prior to welding operation,
ensure workplace safety to pre-
vent fire, explosion and blow-
out.
Remove any combustible
materials in and around the
work site to prevent expo-
sure to such combustible
materials to spattering. If
they cannot be relocated,
cover them with a fireproof
cover.
Do not conduct welding near
combustible gases.
Do not place the welding
power source near combusti-
ble combustible gases, other-
wise, such gases may catch
fire from a spark of electricity
inside the welding power
source as it is electric equip-
ment.
Do not bring hot base metal,
such as a piece immediately
after welding, near combus-
tible materials. When weld-
ing a ceiling, floor or wall,
remove all combustible
materials, i including one
located in hidden places.
WARNING
Prior to welding operation,
ensure workplace safety to pre-
vent fire, explosion and blow-
out.
Firmly connect cables and
insulate the connected parts.
Connect the base metal
cable as close as possible to
the welding section.
Do not weld a sealed tank or
a pipe that contains gas.
Keep a fire extinguisher near
the welding site in case of an
emergency.
CAUTION
Wear protective gears to pro-
tect you and other personnel
against arc flash, flying spatter
and slugs and noise generated
during welding.
Wear protective gears, such
as leather gloves and protec-
tive shoes, to prevent expo-
sure of eyes and skin of
people in the surrounding
area to the arc flash.
Wear protective glasses with
sufficient light blocking struc-
ture or use a protective mask
designed for applied welding
current.
Prepare noise-proof protective
equipment.
