GENERAL THOUGHTS
Safety during welding
ELECTRIC SHOCK CAN KILL: Welding apparatus produce a high voltage. Do not touch the torch, ELECTRIC SHOCK CAN KILL: Welding apparatus produce a high voltage. Do not touch the torch,
welding material connected when the device is turned on to the network. All the elements forming
the welding current circuit can cause electrical shock and should therefore be avoided
touching them with bare hands and by wet or damaged protective clothing. Never work on a wet surface, or use
damaged welding cables. NOTE: Removing the external time when the device is connected to the network, as well as
the use of the device with the covers removed is prohibited! Welding cables, ground cable, earthing terminal and
welding equipment should be kept in good condition, ensuring safety.
ARC RAYS CAN BURN: It is not allowed to look directly at the eyes uncovered and exposed to an ARC RAYS CAN BURN: It is not allowed to look directly at the eyes uncovered and exposed to an
electric arc. Always wear a mask or helmets protected with a suitable filter. Bystanders, nearby,
protected with non-combustible, absorbing radiation screens. Protect
exposed parts of the body suitable protective clothing made of non-combustible material.
FUMES AND GASES CAN BE DANGEROUS: In the welding process are produced noxious fumes FUMES AND GASES CAN BE DANGEROUS: In the welding process are produced noxious fumes
and gases hazardous to health. Avoid breathing these fumes and gases. Workplace should be
adequately ventilated and equipped with exhaust ventilation. Do not weld in confined spaces.
surfaces
the elements to be welded should be free from chemical impurities such as degreasing agents (solvents) which
decompose during welding to produce toxic gases.
ELECTROMAGNETIC FIELDS MAY BE DANGEROUS: Electric current flowing through wires ELECTROMAGNETIC FIELDS MAY BE DANGEROUS: Electric current flowing through wires

Electromagnetic may interfere with pacemakers. Welding cables should be arranged in parallel, as close as possible
to each other.
SPARKS CAN CAUSE FIRE: Sparks generated during welding can cause fire, explosion and burns SPARKS CAN CAUSE FIRE: Sparks generated during welding can cause fire, explosion and burns
unprotected skin. When welding should be wearing welding gloves and protective clothing. Remove
or secure any flammable materials and substances from the workplace. Do not weld
closed containers or receptacles in which there were flammable liquids. Such containers or tanks should be rinsed
prior to welding in order to remove flammable liquid. Do not weld near flammable gases, vapors or liquids. Fire
extinguishing equipment (fire blankets and fire extinguishers powder or snow) should be located close to the
workstation in a conspicuous and easily accessible place.
POWER SUPPLY: Disconnect the power supply before carrying out any work, repairs on the device. POWER SUPPLY: Disconnect the power supply before carrying out any work, repairs on the device.
Regularly check the welding cables. If you note any damage to the wire or insulation should be
removed immediately. Welding wires can not be overwhelmed,
touch sharp edges or hot objects.
WELDED MATERIALS CAN BURN: Never touch the parts to be welded unprotected parts of the WELDED MATERIALS CAN BURN: Never touch the parts to be welded unprotected parts of the
body. While touching and moving the welding material, always use gloves and welding pliers.
Noise can damage hearing: Noise-induced, some processes Noise can damage hearing: Noise-induced, some processes or
devices can damage hearing. Wear hearing protection in situations of increased noise levels.
FIRE OR EXPLOSION: Do not use the machine near flammable substances. Make sure that the FIRE OR EXPLOSION: Do not use the machine near flammable substances. Make sure that the
electrical network is properly configured to work with the welder. Overloading the power supply may
cause fire.
FALLING EQUIPMENT CAN BE DANGEROUS: To move the machine, use the handle of transport. FALLING EQUIPMENT CAN BE DANGEROUS: To move the machine, use the handle of transport.
All the equipment necessary to lift the unit must have sufficient capacity and stable hook. When
moving the machine by forklift truck, the forks must be long enough to protrude beyond the device.
Overload can cause overheating: Do not extend the cycle of welding, welding between cycles allow Overload can cause overheating: Do not extend the cycle of welding, welding between cycles allow
the device to cool. In the case of excessive heating of the device, shorten the cycle time of welding or
reduce the welding current.

any damage caused by failure to comply with the guidelines of this manual manufacturer is not
liable.
HIGH RADIATION FREQUENCY: high radiation
frequency radio signal can zakłucać, alarm systems, work computers and communications
equipment. User is obliged to ensure a qualified electrician correct the problems resulting from
zakłucenia electrical installation. Regularly check and maintain electrical installations. Use
grounding, shielding and anti-surge protection measures to minimize any zakłucenia.
ARC WELDING CAN CAUSE ZAKŁUCENIA: Electromagnetic energy can interfere with electronic ARC WELDING CAN CAUSE ZAKŁUCENIA: Electromagnetic energy can interfere with electronic
equipment such as computers and computer-controlled equipment. Make sure that the hardware
devices in the work environment welders are electromagnetically compatible. To minimize the
potential for interference stick welding wires close to each other, as close to the ground. IN
If electrical noise sensitive spot welding should not be closer than 100m. The device must be connected and
grounded in accordance with this instruction. If noise still persists the user needs to take additional measures such as
changing jobs, the use of shielded cables, filters, linear and securing jobs.
CYLINDER MAY EXPLODE: Use only approved cylinders properly operated regulator. Transported CYLINDER MAY EXPLODE: Use only approved cylinders properly operated regulator. Transported
and stored in an upright position only. Protect from heat sources, tipping and mechanical damage.
Keep in good condition all the elements of the gas.
