BREATHING WELDING FUMES CAN BE HAZARDOUS TO YOUR HEALTH
Inhaling fumes and gases over a long period of time, generated during welding is dangerous and
forbidden .

SAFETY RULES

ELECTRICAL SHOCK COULD BE FATAL
must comply
●Wear dry, hole-free insulating gloves and body protection.
●Do not touch electrode with bare hand. Do not wear wet or damaged gloves and
body protection.
●Do not touch live electrical parts.
●Never touch electrode while in contact with working surface, ground or another
electrode which is connected to a different machine .
●Protect yourself from electric shock by insulating yourself from work and ground.
Use non-flammable, dry insulating material if possible, or use dry rubber mats, dry
wood or plywood, or other dry insulating material big enough to cover your full area
of contact with the work or ground, and watch for fire.
● Never connect up more than 1 electrodes or wires to the machine.
●Turn off the machine, when not in use .
●Disconnect input plug or power before working on machine.
●Frequently inspect input power cord for damage or bare wiring - repair or replace
cord immediately if damaged.
●Be sure input ground wire is properly connected to a ground terminal in disconnect
box or receptacle.
Irritation of the eyes, nose and throat are symptoms of inadequate ventilation. Take immediate
●
steps to improve ventilation. Do not continue welding if symptoms persist.
●Install a natural or forced air ventilation system in the work area.
●Install an adequate ventilation system in the welding and cutting area, if needed
install a system that can remove the fume and vapor accumulated in the entire work
area, to prevent pollution use adequate filtration in discharge.
●In the event of welding in small, confined places, or welding lead, beryllium,
cadmium, zinc, zinc coated or painted materials; also wear a fresh air supplied
respirator in addition to the above mentioned rules .
●Always have a trained watch-person nearby, while working in small confined places.
Avoid working in such confined places if possible.
●If gas cylinders are grouped in a different area, make sure that it is a well-ventilated
area. When not being used, turn off the cylinder valve .
● Shielding gasses such as argon is denser than air and when being used in confined
places, can be inhaled in place of air, and this is dangerous for your health.
●Do not perform welding operations near chlorinated hydrocarbon vapors produced
by degreasing or painting.
