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 

Welding produces electromagnetic field around it. Electromagnetic fields can 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.

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.
