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

• Pay attention to correct working position when lifting a heavy device – risk of injury to

the back.

• 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.

• Do not exceed the maximum allowable load of suspension beams or the transportation

trolley of welding equipment. It is recommended that the wire coil be removed during

lifting or transportation.
