1.4 Protection against electric shock

ELECTRIC SHOCK CAN BE LETHAL
• The feeder must be connected to the nearest socket and placed in a practical and secure position.
Putting the cable in a negligent position in the room and on the 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 burn.
• 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 when the power supply is
turned on.
• The elements under the voltage 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 device earthing can cause life or health hazard.
• 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 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
• Voltage in the input capacitor must be checked upon turning off the device and feeder disconnection
and 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 stay clear of the gas exhaust.
• On inspection, attention must be paid to air change, concurrently avoiding gas inhalation.
• Chemical substances (lubricants, solvents) must be removed from the surfaces of welded details as they
burn and emit toxic smokes under the influence of temperature.
• Welding galvanised details is permitted only when efficient guy-wires are provided with filtration and
access to fresh air. Zinc fumes are highly toxic, an intoxication symptom is so-called metal fever.
