WARNING!  

 
Smoke and gases! 
Smoke and gases can lead to breathing difficulties and poisoning. In addition, solvent 
vapour (chlorinated hydrocarbon) may be converted into poisonous phosgene due to 
the ultraviolet radiation of the arc! 

• 

Ensure that there is sufficient fresh air! 

• 

Keep solvent vapour away from the arc beam field! 

• 

Wear suitable breathing apparatus if appropriate! 

 
Fire hazard! 
Flames may arise as a result of the high temperatures, stray sparks, glowing-hot parts 
and hot slag produced during the welding process. 
Stray welding currents can also result in flames forming! 

• 

Check for fire hazards in the working area! 

• 

Do not carry any easily flammable objects such as matches or lighters. 

• 

Keep appropriate fire extinguishing equipment to hand in the working area! 

• 

Thoroughly remove any residue of flammable substances from the workpiece before 

starting welding. 

• 

Only continue work on welded workpieces once they have cooled down. 

Do not allow to come into contact with flammable material! 

• 

Connect welding leads correctly! 

 
Risk of accidents if these safety instructions are not observed! 
Non-observance of these safety instructions is potentially fatal! 

• 

Carefully read the safety information in this manual! 

• 

Observe the accident prevention regulations in your country. 

• 

Inform persons in the working area that they must observe the regulations! 

 
Danger when coupling multiple power sources

Coupling multiple power sources in parallel or in series has to be carried out by 
qualified personnel and in accordance with the manufacturer's guidelines. Before 
bringing the power sources into service for arc welding operations, a test has to verify 
that they cannot exceed the maximumallowed open circuit voltage. 

• 

Connection of the machine may be carried out by qualified personnel only! 

• 

When decommissioning individual power sources, all mains and welding current leads have 

to be safely disconnected from the welding system as a whole. (Danger due to inverse 
voltages

!

• 

Do not couple welding machines with pole reversing switch (PWS series) or machines for 

AC welding, as a minor error in operation can cause the welding voltages to be combined. 
 

 

WARNING!  

 
Hazards due to improper usage! 
Hazards may arise for persons, animals and material objects if the equipment is not 
used correctly. No liability is accepted for any damages arising from improper usage! 

• 

The equipment must only be used in line with proper usage and by trained or expert staff! 

• 

Do not modify or convert the equipment improperly!
