1. SAFETY OF USE

1.1 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.
1.2 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.

1.3 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.
1.4 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.
• All fitting and safety elements must be stored in one place.
• From the moment of turning on the release, the handle end must be kept away from the body.
• The chassis ground must be mounted to the welded element or as close to it as possible (e.g. to a work
table).
THE DEVICE CAN STILL BE UNDER VOLTAGE UPON FEEDER DISCONNECTION.
• The voltage in the input capacitor must be checked upon turning off the device and disconnecting it
from the power source. One must make sure that the voltage value is equal to zero. Otherwise, the
device elements must not be touched.
1.5 GASES AND FUMES
PLEASE NOTE: GAS MAY BE LETHAL OR DANGEROUS TO HUMAN HEALTH!
• Always keep a certain distance from the gas outlet
• When welding, ensure good ventilation. Avoid inhalation of the gas.
