spatter burn unprotected skin. Use safety gloves and protective clothing.
Danger for fire or explosion
Pay attention to fire safety regulations. Remove flammable or explosive materials from welding
place. Always reserve sufficient fire-fighting equipment on welding place. Be prepared for hazards
in special welding jobs, eg. for the danger of fire or explosion when welding container type work
pieces. Note! Fire can break out from sparks even several hours after the welding work has been
finished!
Mains voltage
Never take welding machine inside a work piece (eg. container or truck). Do not place welding
machine on a wet surface. Always check cables before operating the machine. Change defect cables
without delay. Defect cables may cause an injury or set out a fire. Connection cable must not be
compressed, it must not touch sharp edges or hot work pieces.
Welding power circuit
Isolate yourself by using proper protective clothing, do not wear wet clothing. Never work on a
wet surface or use defect cables. Do not put MIG-gun or welding cables on welding machine or
on other electric equipment. Do not press MIG-gun switch, if the gun is not directed towards a
work piece.
Welding fumes
Take care that there is sufficient ventilation during welding. Take special safety precautions when
welding metals which contain lead, cadmium, zinc, mercury or beryllium.
