General Safety Rules
WARNING! Read all instructions
Failure to follow all instructions
listed below may result in
electric shock, re, and/or
serious injury. The term “power
tool” in all of the warnings listed
below refers to your line-operated
(corded) Arc Welder.
SAVE THESE INSTRUCTIONS
Work area safety1.
Keep work area clean and well a.
lit. Cluttered or dark areas invite
accidents.
Do not operate power tools in b.
explosive atmospheres, such as in
the presence of ammable liquids,
gases or dust. Power tools create
sparks which may ignite the dust or
fumes.
Keep children and bystanders c.
away while operating a power
tool. Distractions can cause you
to lose control.
Electrical safety2.
Avoid body contact with grounded a.
surfaces such as pipes, radiators,
ranges and refrigerators. There is
an increased risk of electric shock if
your body is grounded.
Page 3SKU 97717 For technical questions, please call 1-800-444-3353.
Page 4
Do not touch exposed electrical b.
parts.
Do not expose power tools to rain c.
or wet conditions. Water entering a
power tool will increase the risk of
electric shock.
Do not abuse the cord. Never use d.
the cord for pulling or unplugging the
power tool. Keep cord away from
heat, oil, sharp edges or moving
parts. Damaged or entangled cords
increase the risk of electric shock.
When operating a power tool e.
outdoors, use an extension cord
suitable for outdoor use. Use of
a cord suitable for outdoor use
reduces the risk of electric shock.
Personal safety3.
Stay alert, watch what you are a.
doing and use common sense
when operating a power tool. Do
not use a power tool while you are
tired or under the inuence of drugs,
alcohol or medication. A moment
of inattention while operating power
tools may result in serious personal
injury.
Remove any adjusting key or wrench d.
before turning the power tool on. A
wrench or a key left attached to a
rotating part of the power tool may
result in personal injury.
Do not overreach. Keep proper e.
footing and balance at all times.
This enables better control of the
power tool in unexpected situations.
Power tool use and care4.
Do not force the power tool. Use a.
the correct power tool for your
application. The correct power tool
will do the job better and safer at the
rate for which it was designed.
Do not use the power tool if the b.
switch does not turn it on and
off. Any power tool that cannot
be controlled with the switch is
dangerous and must be repaired.
Disconnect the plug from the c.
power source before making any
adjustments, changing accessories,
or storing power tools. Such
preventive safety measures reduce
the risk of starting the power tool
accidentally.
Use safety equipment. Always wear b.
ANSI-approved safety glasses and
arc shaded, impact safety full face
shield. Safety equipment such as
NIOSH-approved respirator, heavyduty work gloves, non-skid safety
shoes, or hearing protection used
for appropriate conditions will reduce
personal injuries.
Avoid accidental starting. Ensure c.
the switch is in the off-position
before plugging in. Carrying power
tools with your nger on the switch
or plugging in power tools that have
the switch on invites accidents.
Store idle power tools out of the d.
reach of children and do not allow
persons unfamiliar with the power
tool or these instructions to operate
the power tool. Power tools are
dangerous in the hands of untrained
users.
Maintain power tools. Check for e.
misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool’s operation. If damaged,
have the power tool repaired before
use. Many accidents are caused by
poorly maintained power tools.
Page 4SKU 97717 For technical questions, please call 1-800-444-3353.
