SPECIFIC SAFETY WARNINGS FOR WELDERS
WARNING:
In order to avoid mistakes that could cause serious injury, read the following steps
carefully and understand them thoroughly before using this welder.
WELDING FUMES.
Breathing welding fumes can cause suffocation or poisoning without
warning. Keep your head out of welding fumes. Use adequate ventilation at the arc
to safely remove the fumes from your breathing zone and the general area. Use ANSI
approved respirators for the type of welding operation. Protect others from these fumes.
WELDING IN A CONFINED SPACE CAN BE HAZARDOUS.
Always open all covers,
sustain forced ventilation, remove toxic and hazardous materials, and provide a power
disconnect to the welder inside the workspace. Always work with someone who can give
you help from outside the space. Welding can displace oxygen. Always check for safe
breathing atmosphere and provide air-supplied respirators if necessary. Keep in mind
that all normal welding hazards are intensified in a confined space.
ELECTRIC SHOCK. DO NOT
touch live electrical parts. Connect welder to power
source with approved earth ground. Make sure all electrical connections are tight,
clean, and dry. Connect workpiece to approved earth ground. The work lead is NOT a
ground connection and is to be used only to complete the working welding circuit. Do
not operate the welder if the output cable, electrode, or any part of the system is wet.
Do not immerse them in water. Do not allow any body part to come in contact with the
electrode if you are in contact with the material being welded, ground or electrode
from another welder.
PREVENT FIRES. Welding work zones must be kept clear of flammable liquids, such
as gasoline and solvents; combustible solids, such as paper and wood; and flammable
gases, such as acetylene and hydrogen. Provide approved fire barriers and fire
extinguishing equipment for the welding zone. Stay alert for sparks and spatter thrown
into cracks and crevices that can start a smoldering fire. Inspect the work area again one
hour after welding for any potential fire hazards.
WORKING AREA. Keep working area clear of any material not involved in the welding
operation. Keep all equipment, workpieces, and work surfaces clean, dry, and free of
entanglements. Keep lead cables organized and away from your body.
PROTECT BODY FROM ARC BURNS, SPARKS, AND SPATTER.
Wear correct and
approved eye, ear, and body protection. Wear complete body protection, such as clean
and oil-free protective clothing, leather gloves, protective cap, heavy long-sleeve shirt,
cuffless pants, and high leather boots. DO NOT wear jewelry or frayed clothing. Use a
welding helmet with the correct shade of filter for the operation. Protect other people
and property in your working zone from exposure to arc radiation, sparks, and spatter.
HANDLING GAS CYLINDERS.
Regardless of content, pressurized gas cylinders can
explode. Always secure a protector cap in place over the outlet valve assembly when
moving the cylinder.
