Welding arc and spatter
The arc and the reflected radiation from it can damage unprotected eyes. Shield your eyes and
protect your surroundings appropriately before you start welding. The arc and welding spatter will
burn unprotected skin. When welding, use protective clothes and clothing.
Danger of fire and explosion
Observe the fire safety instructions. Remove flammable material in and near the location in which
you will weld. Have the necessary fire extinguishing equipment at hand. Note the dangers posed
by special jobs, such as the risk of fire and explosion when welding tanks. Note! Sparks may ignite
a fire even hours later!
Welding is working with fire, note the special instructions for such work.
Mains voltage
Never bring the welding machine inside the work piece (e.g. container or car). Never set the
welding machine on a wet surface. Replace faulty cables immediately, they create a danger to life
and can cause a fire. See that the connecting cable does not stick, touch sharp edges, or come in
contact with a hot piece.
Welding current circuit
Isolate yourself from the welding current circuit by wearing dry and undamaged protective clothing.
Never work on a wet surface. Never use damaged welding cables. Never set the electrode holder,
earth clamp, or welding cables on top of the power source or other electrical equipment.
Welding fumes
Ensure adequate ventilation. Always take special measures when welding metals containing lead,
cadmium, zinc, mercury, or beryllium.
This equipment’s electromagnetic compatibility (EMC) is designed for use in an
industrial environment. Class A equipment is not intended for use in residential location
