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 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 1.9,
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
be sure 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 and 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
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 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 local
forced ventilation at the arc to remove
