since double open-circuit voltage will be
present.
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 work table as near
the weld as practical.
Insulate work clamp when not connected to
workpiece to prevent contact with any metal
object.
DO NOT
connect more than one electrode or
work cable to any single weld output
terminal.
1.4.2
FUMES AND GASSES CAN BE
HAZARDOUS
Welding produces fumes and
gasses.
Breathing
these
fumes and gasses 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 local
forced ventilation at the arc to remove
welding fumes and gasses.
If ventilation is poor, wear an approved air-
supplied respirator.
Read and understand the Material Safety
Data
Sheets
(MSDS’s)
and
the
manufacturer’s
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 gasses 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
vapors 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 while
wearing an air-supplied respirator. The
coatings and any metals containing these
elements can give off toxic fumes if welded.
1.4.3
BUILD UP OF GAS CAN INJURE
OR KILL
Shut off shielding gas supply
when not in use.
Always ventilate confined
spaces or use approved air-
supplied respirator.
1.4.4
ENCLOSED SPACES CAN
CAUSE A BUILD-UP OF NOXIOUS
FUMES AND OVERHEATING
DO NOT
use in enclosed
spaces where deadly exhaust
gasses can build up and
machine
can
overheat,
causing fire.
1.4.5
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 an approved welding helmet fitted with
a proper shade of filter lenses to protect your
face and eyes from arc rays and sparks
when welding or watching.
(See ANSI Z49.1 and Z87.1 listed in Safety
Standards). Wear approved safety glasses
with side shields under your helmet.
Use protective screens or barriers to protect
others from flash, glare, and sparks; warn
others not to watch the arc.
