•
Do not touch electrode if you are in contact with
the work, ground, or another electrode from a
different machine.
•
Use only weII-maintained equipment. Repair or
replace damaged parts at once. Maintain unit
according to manual.
•
Wear a safety harness if working above floor
level.
•
Keep all panels and covers securely in place.
•
Clamp work cable with good metal-to-metal
contact to work piece or worktable as near the
weld as practical.
•
Insulate work clamp when not connected to
work piece to prevent contact with any metal
object.
•
Do not connect more than one electrode or
work cable to any single weld output terminal.
▲
SIGNIFICANT DC VOLTAGE exists after
removal of input power on inverters.
•
Turn off inverter, disconnect input power, and
discharge input capacitors according to
instructions in Maintenance Section before
touching any parts.
FUMES AND GASES can be
hazardous.
Welding produces fumes and
gases. Breathing these fumes
and gases can be hazardous
to your health.
•
Keep your head out of the fumes. Do not
breathe the fumes.
•
If inside, ventilate the area and/or use exhaust
at the arc to remove welding fumes and gases.
•
If ventilation is poor use an approved air-
supplied respirator.
•
Read the Material Safety Data Sheets
(MSDSs) and the manufacturers’ instructions
for metals, consumables, coatings, cleaners,
and degreasers.
•
Work in a confined space only if it is well
ventilated, or while wearing an air-supplied
respirator. Always have a trained watch-person
nearby. Welding fumes and gases can displace
air and lower the oxygen level causing injury or
death. Be sure the breathing air is safe.
•
Do not weld in locations near degreasing,
cleaning, or spraying operations. The heat and
rays of the arc can react with vapours to form
highly toxic and irritating gases.
•
Do not weld on coated metals, such as
galvanized, lead, or cadmium plated steel,
unless the coating is removed from the weld
area, the area is well ventilated, and if
necessary, while wearing an air-supplied
respirator. The coatings and any metals
containing these elements can give off toxic
fumes if welded.
ARC RAYS can burn eyes
and skin.
Arc rays from the welding
process
produce intense
visible and invisible (ultraviolet
and infrared) rays that can
burn eyes and skin. Sparks fly
off from the weld.
•
Wear a welding helmet fitted with a proper
shade of filler to protect your face and eyes
when welding or watching (see Safety
Standards).
•
Wear approved safety glasses with side shields
under your helmet.
•
Use protective screens or barriers to protect
others from flash and glare; warn others not to
watch the arc.
•
Wear protective clothing made from durable,
flame-resistant material (leather and wool) and
foot protection.
WELDING can cause fire or
explosion.
Welding on closed
containers, such as tanks,
drums, or pipes, can cause
them to blow up. Sparks can
fly off from the welding arc.
The flying sparks, hot work piece, and hot
equipment can cause fires and burns. Accidental
contact of electrode to metal objects can cause
sparks, explosion, overheating, or lure. Check and
be sure the area is safe before doing any welding.
•
Protect yourself and others from flying sparks
and hot metal.
•
Do not weld where flying sparks can strike
flammable material.
•
Remove all flammables within 35 ft (10.7 m) of
the welding arc. If this is not possible, tightly
cover them with approved covers.
