Noise can damage your hearing. Protect yourself suitably to avoid hearing damage.
The welding arc can cause burns.
Keep the tip of the welding gun/torch far from your body and far from other
persons.
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 phosphate gas.
 If you develop momentary eye, nose, or throat irritation when welding, stop welding immediately. This is an
indication that ventilation is not adequate. Do not continue to weld until ventilation is improved.
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 wet surfaces when
welding.

Disconnect the power supply before working on the welding machine.

Do not weld with deteriorated or damaged cables.

Frequently inspect cables for wear, cracks, or damage. Replace those with excessively worn insulation to avoid a
possible lethal shock from bared cable.

Do not touch bare electrical parts.

Ensure that all of 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 and 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; a damaged power cable 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 you to the dangerous risk of electric shock.
