3. SAFETY OF USE
ATTENTION! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in an electric shock, fire and/or serious injury or death.

3.1. GENERAL NOTES

• Take care of your own safety and the one of third parties by reviewing and strictly following the instructions, included
in the operating manual of the device.
• Only qualified and skilled personnel can be allowed to start, operate, maintain and repair the machine.
• The machine must never be operated contrary to its intended purpose.
3.2. PREPARATION OF WELDING WORK SITE
WELDING OPERATIONS MAY CAUSE FIRE OR EXPLOSION!
• Strictly follow the occupational health and safety regulations applicable to welding operations and make sure to
provide appropriate fire extinguishers at the welding work site.
• Never carry out welding operations in flammable places that pose the risk of material ignition.
• Never carry out welding operations in an atmosphere containing flammable particles or vapours of explosive
substances.
• Remove all flammable materials within 12 meters from the welding operations site and if removal is not possible
cover flammable materials with fire retardant covering.
• Use safety measures against sparks and glowing particles of metal.
• Make sure that sparks or hot metal splinters do not penetrate through the slots or openings in the coverings, shields
or protective screens.
• Do not weld tanks or barrels that contain or have contained flammable substances. Do not weld in the vicinity of
such containers and barrels.
• Do not weld pressure vessels, pipes of pressurised installations or pressure trays.
• Always ensure adequate ventilation.
• It is recommended to take a stable position prior to welding.
3.3. PERSONAL PROTECTION EQUIPMENT
ELECTRIC ARC RADIATION CAN CAUSE DAMAGE TO EYES AND SKIN!
• When welding, wear clean, oil stain free protective clothing made of non-flammable and non-conductive material
(leather, thick cotton), leather gloves, high boots and protective hood.
• Before welding remove all flammable or explosive items, such as propane butane lighters or matches.
• Use facial protection (helmet or shield) and eye protection, with a filter featuring a shade level matching the sight of
the welder and the welding current. The safety standards suggest colouring No. 9 (minimum No. 8) for each current
below 300 A. A lower colouring of the shield can be used if the arc is covered by the workpiece.
• Always use approved safety glasses with side protection under the helmet or any other cover.
• Use guards for the welding operations site in order to protect other people from the blinding light radiation or
projections.
• Always wear earplugs or another hearing protection to protect against excessive noise and to avoid spatter entering
the ears.
• Bystanders should be warned to not look at the arc.
3.4. PROTECTION AGAINST ELECTRIC SHOCK
ELECTRIC SHOCK CAN BE LETHAL!
• The power cable must be connected to the nearest socket and placed in a practical and secure position. Positioning
the cable negligently in the room and on a surface which was not checked must be avoided as it can lead to
electrocution or fire.
• Touching electrically charged elements can cause electrocution or serious burns.
• Electrical arc and the working area are electrically charged during the power flow.
• Input circuit and inner power circuit of the devices are also under voltage charge when the power supply is turned
on.
• The elements under the voltage charge must not be touched.
• Dry, insulated gloves without any holes and protective clothing must be worn at all times.
• Insulation mats or other insulation layers, big enough as not to allow for body contact with an object or the floor,
must be placed on the floor.
• The electrical arc must not be touched.
• Electrical power must be shut down prior to cleaning or electrode replacement.
• It must be checked if the earthing cable is properly connected or the pin is correctly connected to the earthed socket.
Incorrect connection of the earthing can cause life or health hazard.
• The power cables must be regularly checked for damage or lack of insulation. Damaged cables must be replaced.
Negligent insulation repair can cause death or serious injury.
• The device must be turned off when it is not in use.
• The cable mustn't be wrapped around the body.
• A welded object must be properly grounded.
• Only equipment in good condition can be used.
• Damaged device elements must be repaired or replaced. Safety belts must be used when working at height.
