1.0 Safety Precauons
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The electrode and work circuit is
electrically live whenever the output is on. The input
power circuit and machine internal circuits are also
live when power is on. In semiautomac or automac
wire welding, the wire, wire reel, drive roll housing,
and all metal parts touching the welding wire are
electrically live. Incorrectly installed or improperly
grounded equipment is a hazard.
Do not touch live electrical parts.
Wear dry, sound insulang gloves and body
protecon.
Insulate yourself from work and ground using dry
insulang mats or covers big enough to prevent any
physical contact with the work ground.
Addional safety precauons are required when any
of the following electrically hazardous condions
are present: in damp locaons or while wearing wet
clothing; on metal structures such as oors, grangs,
or scaolds; when in cramped posions such as sing,
kneeling, or lying; or when there is a high risk of
unavoidable or accidental contact with the work piece
or ground. For these condions, use the following
equipment in order presented: 1) a semiautomac DC
constant voltage (wire) welder, 2) a DC manual (sck)
welder, And, do not work alone!
Disconnect input power before installing or servicing
this equipment. Lockout/tagout input power according
to Safety Standards.
Properly install and ground this equipment according
to naonal and local standards.
Always verify the supply ground - check and ensure
that input power cable ground wire is properly
connected to ground terminal in the receptacle outlet.
When making input connecons, aach proper
grounding conductor rst - double-check connecons.
Frequently inspect input power cable for damage or
bare wiring - replace cable immediately if damaged -
bare wiring can kill.
Turn o all equipment when not in use.
Do not use worn, damaged, under sized, or poorly
spliced cables.
Do not drape cables over your body.
If earth grounding of the work piece is required,
ground it directly with a separate cable.
Do not touch electrode if you are in contact with the
work, ground, or another electrode from a dierent
machine.
Use only well-maintained equipment. Repair or
replace damaged parts at once. Maintain unit
according to manual.
Wear a safety harness if working above oor 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
praccal.
Insulate work clamp when not connected to work
piece to prevent contact with any metal object.
Welding produces fumes and gases. Breathing these
fumes and gases can be hazardous to your health.
FUMES AND GASES can be hazardous.
Keep your head out of the fumes. Do not breathe the
fumes.
If inside, venlate the area and/or use local forced
venlaon at the arc to remove welding fumes and
gases.
If venlaon is poor, wear an approved respirator.
Read and understand the Material Safety Data Sheets
(MSDS’s) and the manufacturer’s instrucons for
metals, consumable, coangs, cleaners, and de-
greasers.
Work in a conned space only if it is well venlated,
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 locaons near de-greasing, cleaning, or
spraying operaons. The heat and rays of the arc can
react with vapours to form highly toxic and irritang
gases.
Do not weld on coated metals, such as galvanized,
lead, or cadmium plated steel, unless the coang
is removed from the weld area, the area is well
venlated, and while wearing an air-supplied
respirator. The coangs and any metals containing
these elements can give o 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 y o from the weld.
