There are many risks associated with the use of oxyacetylene welding. Appropriate safety
measures should be taken when working with this equipment.
• Never use oxygen to air-blow the
workplace or your clothes. Any spark may cause a fire.
• Do not work with damaged or leaking equipment.
• Do not use the torch as a hammer or to remove burrs
from work material.
3
• Before welding or cutting, make sure that the working
area is in perfect conditions to avoid accidents.
• Work in well-ventilated areas.
Work Area
• Always keep a fire extinguisher handy.
• Use reverse flow check valves or check
valves on all connections. These safety valves help prevent
accidents caused by gas backflow or flame blowback
in the system.
• Always use welding glasses to protect your eyes from
sparks or flares.
• Always wear special welding gloves and watch out for
sparks that could fall into your wrists.
• Do not wear torn or broken
clothing: a spark could ignite the fabric.
Safety equipment
• Do not smoke near the cylinders.
• Handle the cylinders with care. Avoid
dropping or hitting them and do not expose them to heat
or flame. Remember that the cylinders must always be in
an upright position.
• Secure the cylinders in place before
making connections to prevent them from falling out. It is
recommended that they be mounted and chained to a
loading trolley.
• Never use a cylinder that is dented.
• Cylinder protection caps should be in place whenever
you move the cylinders or when you are not using them.
• Empty cylinders must be stored in a specific location and
clearly marked as "Empty"”.
• Under no circumstances should you alter or force the
cylinder connections.
Cylinder handling
• Do not smoke near the connections.
• Do not use oil or grease on the
connections under any circumstances. The equipment
does not require lubrication. Oil and lubricants burn
violently in the presence of pressurized oxygen.
• Make sure that all connections and
hoses are in good condition. Replace any damaged ones
immediately.
• When installing the connections, make sure that they are
tight.
• Use soapy water to detect any
leaks and correct them before turning on.
• Under no circumstances allow damaged
or missing "O" rings on the cone tip. Should this happen,
gases will mix inside the material, which could cause the
flame to be reversed or an explosion to occur.
Connections
• Purge the oxygen and acetylene
passages separately before switching on (see page 5 and
6).
• Avoid wasting gas by using the proper pressure settings.
If gauges indicate external pressure, correct immediately.
• The working pressure in the acetylene gauge should
NEVER exceed 15 PSI (1.03 bar).
• Purge the entire system after each use
(see page 9). DO NOT disconnect the equipment with the
cylinder valves open.
• In case of a leak, move the cylinder to an open area away
from flammable material and immediately report it to your
supervisor or to Civil Protection.
