1.3 INTERNATIONAL SAFETY
SYMBOL -
The symbols shown and defined in Section
1: Safety are used throughout this manual to
call attention to and identify possible
hazards.
The international warning symbol shown
above is used on all decals, labels and signs
that concern information pertaining to bodily
harm. When you see the international
warning symbol,
pay extremely careful
attention , and follow the given instructions
or indications to avoid any possible hazard.
1.4 ARC WELDING HAZARDS
1.4.1 ELECTRICAL 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 semi-
automatic or automatic 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 weld with the electrode holder
connected to the negative (-) port, and the
work piece connected to the vehicle: Bodily
harm and equipment damage may occur.
DO NOT touch live electrical parts.
Wear dry, hole-free insulating gloves and
body protection.
Insulate yourself from work and ground using
dry insulating mats or covers big enough to
prevent any physical contact with the work or
ground.
DO NOT use AC output in damp areas, if
movement is confined, or if there is a danger
of falling.
Additional safety precautions are required
when working in electrically hazardous
conditions such as in damp locations or while
wearing wet clothing; on metal structures
such as floors, gratings, or scaffolds; when in
cramped positions such as sitting, kneeling,
or lying; or when there is a high risk of
unavoidable or accidental contact with the
work piece or ground.
DO NOT work alone!
Disconnect input power or stop engine
before installing or servicing this equipment.
Lockout/tag out input power according to
OSHA29 CFR1910.147 (see
Section 1.10,
Principal Safety Standards ).
Properly install and ground this equipment
according to its Owner’s Manual and
national, state, and local codes.
Always verify the supply ground: check and
ensure that input power cord ground wire is
properly connected to ground terminal in
disconnect box or that cord plug is connected
to a properly grounded receptacle outlet.
When making input connections, attach
proper grounding conductor first and double-
check connections.
Frequently inspect input power cord for
damage or bare wiring; replace cord
immediately if damaged—bare wiring can
kill.
Turn off all equipment when not in use.
DO NOT use worn, damaged, undersized, 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 different machine.
Use only well-maintained equipment. Repair
or replace damaged parts at once. Maintain
unit according to manual.
DO NOT touch electrode holders connected
to two welding machines at the same time
