• Protect the environment from welding spatter. Remove flammable materials, such as
flammable fluids, 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
container-type work pieces.
• Never direct the spark spray 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 the machine.
• 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.
• 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 can
be lethal and 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 authorised 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 sufficient supply of fresh air, particularly in closed spaces. You can also ensure the
supply of clean and sufficient breathing air by using a fresh-air mask.
• Take extra precautions when working on metals or surface-treated materials containing
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 lift
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 allowed load of suspension beams or the transportation
trolley of welding equipment.
• It is recommended that the wire coil be removed during lifting or transportation.
environment
• Protect welding machines from heavy rain and direct sunshine even if it were suitable for
outdoor use.
• Always store the machine in a dry and clean space.
• Protect the machine from sand and dust during use and in storage.
• The recommended operating temperature range is -20 to +40 °C. The machine’s operation
efficiency decreases and it becomes more prone to damage if used in temperatures in
excess of 40 °C.
• Place the machine so that it is not exposed to hot surfaces, sparks or spatter.
