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.

Rev. 27.03.2017
• Chemical substances (lubricants, solvents) must be removed from the surfaces of welded objects as
they burn and emit toxic smokes under the influence of temperature.
• The welding of galvanised objects is permitted only when efficient ventilation is provided with filtration
and access to fresh air. Zinc fumes are very toxic, an intoxication symptom is the so called zinc fever.

3. OPERATION
3.1 GENERAL NOTES
• The device must be applied according to its purpose, with observance of OHS regulations and
restrictions resulting from data included in the rating plate (IP level, operation cycle, supply voltage,
etc.).
• The machine must not be opened as it will cause warranty loss and, in addition, exploding, unshielded
elements can cause serious injuries.
• The producer does not bear any responsibility for technical changes in the device or material losses
caused by the introduction of the said changes.
• In case of incorrect device operation, contact the service centre.
• Louvers must not be shielded – the welder must be positioned at 30 cm distance from objects
surrounding it.
• The welder must not be kept under your arm or near to your body.
• The machine must not be installed in rooms with aggressive environments, high dustiness and near
devices with high electromagnetic field emission.
3.2 DEVICE STORAGE
• The machine must be protected against water and moisture.
• The welder must not be positioned on heated surfaces.
• The device must be stored in a dry and clean room.
3.3 CONNECTING THE DEVICE
3.3.1 Connecting the power
• Connection of the device must be performed by a qualified person. In addition, a person with required
qualifications should check if the earthing or electrical installation with protection system is in line with
the safety regulations and if they operate correctly.
• The device must be placed near the work station.
• Connection of excessively long conduits to the machine must be avoided.
• One-phase welders should be connected to the socket fitted with an earthing prong.
