•
Avoid having any type of fuel, such as cigarette lighters or matches, on your person as you weld.
•
Ensure that there is a fire extinguisher in the welding area.
Electric arc welding produces toxic fumes.
•
Provide adequate ventilation in the welding area at all times.
•
Do not weld on galvanized zinc, cadmium, or lead beryllium materials unless you are POSITIVE that
sufficient ventilation is provided. These materials produce toxic fumes.
•
Do not weld in areas close to degreasing or spraying operations. Chlorinated hydrocarbon vapors may react
with the ultra-violet rays and form highly toxic phosphine gas.
•
If you develop eye, nose, or throat irritation during welding, stop welding immediately. This is an indication
that ventilation is not adequate. Do not continue to weld until proper ventilation is provided.
Noise can damage your hearing.
Protect yourself to avoid hearing damage.
The welding arc can cause burns.
Keep the tip of the welding gun, torch, or arc welding clamp far from your body
and from other persons.
ELECTRIC SHOCK CAN KILL.
Exposed, electrically hot conductors, other bare metal in the welding circuit, or ungrounded, electrically hot equipment
can fatally shock a person whose body becomes a conductor. Do not stand, sit, lie, lean on, or touch a wet surface when
welding.
•
Disconnect the power supply before working on the welding machine.
•
Do not work with deteriorated or damaged cables.
•
Frequently inspect cables for wear, cracks, and damage. Replace cables with excessively worn insulation to
avoid possible lethal shock from bare wire.
•
Do not touch bare electrical parts.
•
Ensure that all the panels covering the welding machine are firmly secured in place when the machine is
connected to the power supply.
•
Insulate yourself from the workbench and from the floor (ground); use insulating footwear and gloves.
•
Keep gloves, footwear, clothes, the work area, and the welding equipment clean and dry.
•
Check the machine power cable frequently; the power cable must be free from damage to the insulation.
BARE CABLES ARE DANGEROUS. Do not use the machine if the power cable is damaged; it must be
replaced immediately.
•
If it is necessary to open the machine, first disconnect the power supply. Wait five (5) minutes to allow the
capacitors to discharge. Failure to take this precaution may expose the operator to the dangerous risk of electric
shock.
