Welding may damage your body or others. Take protection during operation.
Only professionally trained technicians should install, set-up, operate, 

maintain and repair the equipment.
Do not maintain or repair the machine when the machine is connected to 

power.
Electric shock can kill.
Never touch electrical parts.
Wear dry, hole-free gloves and clothes to insulate yourself.
Insulate yourself from work and ground using dry insulation. Make certain 

the insulation is large enough to cover your full area of physical contact with 

work and earth.
Ensure equipment is correctly installed. Earth the work or metal to be 

welded according the operation manual.
Ensure equipment is operated in a safe position.
Fumes and gases can be dangerous!
Welding may produce fumes and gases hazardous to health. Avoid breathing 

these fumes and gases.
Use sufficient ventilation and/or exhaust at the arc to keep fumes and gases 

away from the breathing zone.
Welding sparks can cause fire or explosion.
Remove fire hazards from the welding area. If this is not possible, cover 

them to prevent the welding sparks from starting a fire. Remember that 

welding sparks and hot welding material can easily go through small cracks 

and openings to adjacent areas.
Do not weld enclosed tanks or containers.
Have a fire extinguisher readily available.
Hot parts can cause burns.
Do not touch hot parts.
Use torch after cooling or use the welding blow lamp.
Personnel with a heart-pacemaker should keep away from the welding arc.
Rotating parts may be dangerous.
Keep clear of rotating parts (eg fan).
Keep machine parts in a safe position.
