LF Declaration

Consult the data plate on the equipment for the power supply requirements. Due to the elevated 
absorbency of the primary current from the power supply network, high power systems affect the 
quality of power provided by the network. Consequently, connection restrictions or maximum 
impedance requirements permitted by the network at the public network connection point must be 
applied to these systems. In this case the installer or the user is responsible for ensuring the equipment 
can be connected, consulting the electricity provider if necessary.

Materials and their disposal

The equipment is manufactured with materials, which do not contain any toxic or poisonous 
materials dangerous to the operator. When the equipment is scrapped, it should be dismantled 
separating components according to the type of materials. Do not dispose of the equipment with 
normal waste. The European Directive 2002/96/EC on Waste Electrical and Electronic Equipment states 
the electrical equipment that has reached its end of life must be collected separately and returned to an 
environmentally compatible recycling facility.

Handling of compressed gas cylinders and regulators

All cylinders and pressure regulators used in welding operations should be handled with care.
Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a cylinder.
Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.
Always secure the cylinder safely. Never deface or alter any cylinder.

The following signs and explanations are to remind the user of the potential 

risks involved and the dangers of misuse or mistreatment of the welding 

machine.

!

RUNNING PARTS MAY BE DANGEROUS!

Keep away from running components, 
including the fan.

BE AWARE OF SPARKS AND SPATTER

Wear protective clothing, such as leather 
gloves, Flame retardant overalls, boots and 
eyewear.

DO NOT TOUCH THERMAL COMPONENTS!

Thermal components may cause severe burns 
when in contact with unprotected skin.

ELECTRIC SHOCKS CAN KILL!

Never touch electrical parts. Keep the 
equipment in good condition, replace 
damaged parts, undertake regular 
maintenance according to the instructions.
