SPECIFIC SAFETY RULES FOR INVERTER MIG/
FLUX/STICK WELDER
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 suocation 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.
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, cuess pants, and high leather boots. DO NOT wear jewellery 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. A broken o valve could release the pressurized contents
and cause the cylinder to be hurled about at dangerously high speeds, causing
serious property damage, personal injury, or death. Always use safe methods when
moving gas cylinders. Always secure a gas cylinder to a wall or approved cylinder
cart with a chain before using or storing.
PROTECT GAS CYLINDERS FROM HEAT OR DAMAGE. An excess of heat can
cause the pressurized gas to expand and explode the cylinder. Never weld on the
