In environments classified as dangerous, only use S-marked welding equipments with
•
a safe idle voltage level. These work environments include, for example, humid, hot or
small spaces, where the user may be directly exposed to the surrounding conductive
materials.
Do not use arc welding equipment for pipe thawing.
•
spatter and fire safety
Welding is always classified as hot work, so pay particular attention to the fire safety
•
regulations during welding and after it.
Remember that fire can break out from sparks, even several hours after the welding work
•
is completed.
Protect the environment from welding spatter. Remove combustible materials, such as
•
flammable liquid from the welding vicinity, and supply the welding site with adequate
fire fighting equipment.
In special welding jobs, be prepared for hazards such as fire or explosion when welding
•
inside enclosed work spaces, such as tanks and vessels. Ensure you have authority to
work.
Never direct the sparks or cutting spray of a grinder toward the welding machine or
•
flammable materials.
Beware of hot objects or spatter falling on the machine when working above. Welding in
•
flammable or explosive sites is absolutely forbidden.
general electric safety
Only connect the welding machine to an earthed electric network. Note the
•
recommended mains fuse size.
Do not take the welding machine inside a container, vehicle or similar work piece unless
•
authorized to do so.
Do not place the welding machine on a wet surface and do not work on a wet surface.
•
Do not allow the mains cable to be directly exposed to water.
•
Ensure cables or welding torches are not squashed by heavy objects and that they are
•
not exposed to sharp edges or a hot work piece.
Make sure that faulty and damaged welding torches are changed immediately as they
•
may cause electrocution or fire.
Remember that the cable, plugs and other electric devices may be installed or replaced
•
only by an electrical contractor or engineer authorized to perform such operations.
Turn off the welding machine when it is not in use.
•
welding power circuit
Insulate yourself from the welding circuit by using dry and undamaged protective
•
clothing.
Never touch the work piece and welding rod, welding wire, welding electrode or contact
•
tip at the same time.
Do not put the welding torch or ground cable on the welding machine or other electric
•
equipment.
welding fumes
Ensure proper ventilation and avoid inhaling the fumes.
•
Ensure a sufficient supply of fresh air, particularly in closed spaces. You can also ensure
•
an adequate supply of clean breathing air by using a filtered fresh-air mask.
Take extra precautions when working on metals or surface-treated materials containing,
•
for example, lead, cadmium, zinc, mercury or beryllium.
transportation, lifting and suspension
Never pull or lift the machine by the welding torch or other cables. Always use the lifting
•
points or handles designed for that purpose.
Only use a transport unit designed for the equipment. Try to transport the machine in an
•
upright position, if possible.
Never lift a gas cylinder and the welding machine at the same time. There are separate
•
provisions for gas cylinder transportation.
Never use a welding machine when suspended unless the suspension device has been
•
designed and approved for that particular purpose.
