 WARNING 

 

Risk of injury due to improper clothing! 
During arc welding, radiation, heat and voltage are sources of risk that cannot be 
avoided. The user has to be equipped with the complete personal protective equipment 
at all times. The protective equipment has to include: 

•  Respiratory protection against hazardous substances and mixtures (fumes and vapours); 

otherwise implement suitable measures such as extraction facilities. 

•  Welding helmet with proper protection against ionizing radiation (IR and UV radiation) and 

heat. 

•  Dry welding clothing (shoes, gloves and body protection) to protect against warm 

environments with conditions comparable to ambient temperatures of 100 °C or higher and 
arcing and work on live components. 

•  Hearing protection against harming noise. 

 

 

 WARNING 

 

Risk of injury due to radiation or heat! 
Arc radiation results in injury to skin and eyes. 
Contact with hot workpieces and sparks results in burns. 

•  Use welding shield or welding helmet with the appropriate safety level (depending on the 

application)! 

•  Wear dry protective clothing (e.g. welding shield, gloves, etc.) according to the relevant 

regulations in the country in question! 

•  Protect persons not involved in the work against arc beams and the risk of glare using 

safety curtains! 

 

 

 WARNING 

 

Explosion risk! 
Apparently harmless substances in closed containers may generate excessive pressure 
when heated. 

•  Move containers with inflammable or explosive liquids away from the working area!

 

•  Never heat explosive liquids, dusts or gases by welding or cutting! 

 

Fire hazard! 
Due to the high temperatures, sparks, glowing parts and hot slag that occur during 
welding, there is a risk of flames. 

•  Be watchful of potential sources of fire in the working area! 
•  Do not carry any easily inflammable objects, e.g. matches or lighters. 
•  Ensure suitable fire extinguishers are available in the working area! 
•  Thoroughly remove any residue of flammable materials from the workpiece prior to starting 

to weld. 

•  Only further process workpieces after they have cooled down. Do not allow them to contact 

any flammable materials!
