1.3 Operation Safety

Please read and follow these operational safety instructions when installing, operating and

servicing the welding gun.
Welding arc and welding spatter
Welding arc can harm unprotected eyes. Also be aware of the risks to other people in and

around the working area, as reflected arc and arc flash presents a serious risk. Welding arc

and hot spatter will burn unprotected skin. Use specified, good quality safety equipment and

protective clothing.
Danger for fire or explosion
Observe the local fire safety regulations and complete an adequate risk assessment, prior to

commencing work. Remove flammable or explosive materials from welding place. Always

ensure there is adequate fire-fighting equipment available. Be aware of welding hazards eg.

the danger of fire or explosion when welding container type work pieces or enclosed spaces.

NOTE!

Fire can start from welding sparks and hot spatter, even several hours after the welding

work has finished!

Mains voltage
Never take the welding machine inside a work piece (eg. container or truck). Do not place

the welding machine on a wet surface. Always check cables before operating the machine.

Change defective cables without delay. Defective cables may cause an injury or increase

the risk of fire. Connection cables and hoses should be protected from damage from heavy

objects, sharp edges or hot work pieces.
Welding power circuit
Protect yourself by using proper protective clothing suitable for the welding application

and environment. Do not work in wet or damp conditions. Do not wear wet clothing when

welding. Never use equipment with defective or damaged cables. Unless in a designed gun

holder, do not place the welding gun on the welding machine if the machine is live. Never

point the welding gun towards your face or that of others.
Welding fumes
Ensure there is sufficient ventilation during welding. Observe safety recommendations and

precautions when welding metals which contain lead, cadmium, zinc, mercury or beryllium

and other harmful substances. Ensure you use appropriate protective respiratory equipment

suitable for the welding application, environment and materials being welded.
