b)
Get rid of flammable or explosive objects such as propane-butane
lighters or matches before welding.
c)
Use face protection (helmet or shield) and eye protection with a filter
with a degree of darkness matched to the welder's vision and welding
current. The safety standards suggest a tint of No. 9 (minimum No. 8)
for any amperage below 300 amperes. Lower shielding tints may be
used if the arc covers the workpiece.
d)
Always use approved safety glasses with side shields under the helmet
or other shielding.
e)
Use a work area shield to protect others from glare or spatter.
f)
Always wear earplugs or other hearing protection to protect against
excessive noise and to prevent splatter from entering the ears.
g)
Bystanders should be warned before looking at an electric arc.

PROTECTION AGAINST SHOCK
Electric shock can be fatal.
a)
Plug the power cord into the nearest outlet and arrange it in a
practical and safe manner. Avoid spreading the cable carelessly
around the room on an unstudied surface, which may result in electric
shock or fire.
b)
Contact with electrically charged parts may cause electric shock or
severe burns.
c)
The electric arc and the working area are electrically charged when
current flows.
d)
The input circuit and the internal current circuit of the unit are also
energized when the power is turned on.
e)
Do not touch electrically energized parts.
f)
Wear dry, lint-free, insulated gloves and protective clothing.
g)
Use insulating mats or other insulating coverings on the floor that are
large enough to prevent body contact with the object or floor.
h)
Do not touch the electric arc.
i)
Turn off electrical power before handling, cleaning, or replacing an
electrode.
j)
Ensure that the grounding cable is properly connected and that the
plug is properly connected to a grounded outlet. Improper grounding
of the unit may result in a risk to life or health.
k)
Regularly inspect current cables for damage or lack of insulation. A
damaged cable should be replaced. Careless repair of insulation may
result in death or personal injury.
