vi
HW1484722
WARNING
• Be sure to observe the following warnings and use protectors to
protect yourself or other people from the fumes or gases
generated at welding and short of the oxygen.
• In order to prevent gas poisoning or suffocation, be sure to ventilate sufficiently or use
an inhaler, etc. when welding at a place specified by regulations such as labor safety
and sanitary regulations or hypoxia preventive regulations.
• In order to prevent dust trouble or gas poisoning due to the fumes or gases, use a
local air exhaust facility specified by regulations such as labor safety and sanitary
regulations or dust trouble preventive regulations or use effective protectors for
breathing.
Fumes or gases generated at welding may harm your health.
• When welding within such areas as a tank, a boiler, or a ship’s hold, be sure to
ventilate sufficiently or use an inhaler, etc. in order to prevent or offset any actual or
potential oxygen shortage.
Gas heavier than air such as carbon dioxide gas or argon gas stays at the bottom.
• When welding in a small space, be sure to ventilate the site sufficiently or use an
inhaler. At the same time, operations must be done under trained supervisor.
Welding operations at a small space may result in short of the air, causing a
person to be suffocated.
• Do not perform welding near degreasing, cleaning, or spraying operations.
Failure to observe this warning may generate extremely noxious gases.
• Before welding coated steel plates, be sure to ventilate sufficiently or use protectors
for breathing.
Welding such coated steel plates generates noxious fumes or gases.

vii
HW1484722
WARNING
Observe the following cautions to prevent fire, explosion, or
rupture.
• Spatter and heated base metal just after welding may cause fire.
• Unstable electrical contacts (e.g. between the terminals, between
the jig and the workpiece, etc.) may cause fire.
• Generating arc in a vessel containing gasoline or other
flammables may result in explosion.
• Welding a sealed tank or pipe may result in burst.
• Remove inflammables so that they will not get spattered. If they cannot be removed,
use the inflammables with nonflammable covers.
Spatters or hot base metal immediately after welding may result in fire.
• Do not weld near flammable gases.
If arc is generated in a container (for inflammables) in which gasoline or the like is
put, the container may explode.
• Do not make hot base metals immediately after welding close to inflammables.
• Remove inflammables at the hidden side when welding ceiling, floor, or wall.
Failure to observe this caution may result in fire.
