GENERAL SAFETY INFORMATION
Electric shock
ELECTRIC SHOCK CAN KILL.
•
Do not touch the parts under high voltage;
•
Disconnect the power supply from mains before any intervention;
•
Operator must be insulated from the weld piece and from the ground, using insulated gloves
and clothing;
•
Do not work with damaged or poorly connected cables or with slack cable clamps;
•
Keep work clothing and your body, dry;
•
Do not work in moist or wet areas;
•
Do not lean against the weld pieces;
•
Protect the power source with a suitable circuit breaker, placed near the welder if possible;
•
Do not use the machine if any of its protection parts have been removed;
•
Make sure that the mains in use is earthed.
Explosions
•
Do not weld above or near containers under high pressure;
•
Do not weld recipients that contain fuel or inflammables;
•
Do not weld in areas containing explosive dusts, gases or vapours;
•
Always use a pressure gauge to connect the machine gas hose to the bottle;
•
Do not use damaged or leaking bottles;
•
Do not use bottles that do not show what kind of gas they contain;
•
Do not expose bottles to sources of excessive heat;
•
Never mix the gas inside bottles;
•
Have always refilled bottles by specialized companies;
•
Avoid accidental contact between bottles and the electrode or other parts under voltage;
•
Replace gas hoses that show damage;
•
Keep pressure reducer efficient;
•
Use only pressure reducers manufactured for the specific gas.
Fire
•
Avoid flames being generated by sparks, slag and incandescent materials;
•
Make sure that fire extinguishing devices are available near the work area;
•
Remove inflammable and combustible materials from the area.
Burns
•
Protect the body from burns and ultraviolet radiations by wearing protective flameproof clothing (gloves –
headwear – shoes – helmets, etc.);
•
Wear a welding helmet;
•
Keep the electrode or torch tip away from your body and other people's bodies;
•
Make sure that there is first aid equipment near the work area;
•
Do not wear contact lenses, the intense heat of the arc could glue them to the cornea;
•
Replace mask glass if it is damaged or not suited to the specific welding job;
•
Wait for the welded parts to cool completely before touching them with your hands.
Fumes
Welding produces fumes and harmful metallic dusts, therefore;
•
If working in closed areas, use exhaust fans;
•
Clean the weld piece if solvents or other materials that can release toxic gases are present on its surface;
•
Do not weld metals covered with or containing lead, cadmium, graphite, zinc, chrome, mercury, if there is not
an adequate exhaust fan;
•
WARNING: do not use oxygen for ventilation!!!
Radiation
The welding arc produces radiation that can damage eyes and burn the skin. The welding arc is considered
dangerous up to a distance of 15m (50 ft). Use suitable protection.
