Electrical Safety
1. Grounded tools must be plugged
into an outlet properly installed and
grounded in accordance with all
codes and ordinances. Never
remove the grounding prong or
modify the plug in any way. Do not
use any adapter plugs. Check with
a qualified electrician if you are in
doubt whether the outlet is properly
grounded. If the tool should
electrically malfunction or break down,
grounding provides a low resistance
path to carry electricity away from the
user.
2. Double insulated tools are
equipped with a polarized plug (one
blade is wider than the other). This
plug will fit in a polarized outlet
only one way. If the plug does not
fit fully in the outlet, reverse the
plug. If it still does not fit, contact a
qualified electrician to install a
polarized outlet. Do not change the
plug in any way. Double insulation
eliminates the need for the three wire
grounded power cord and grounded
power supply system.
3. Avoid body contact with grounded
surfaces such as pipes, radiators,
ranges, and refrigerators. There is
an increased risk of electric shock if
your body is grounded.
4. Do not expose power tools to rain
or wet conditions. Water entering a
power tool will increase the risk of
electric shock.
5. Do not abuse the Power Cord.
Never use the Power Cord to carry
the tool or pull the Plug from an
outlet. Keep the Power Cord away
from heat, oil, sharp edges, or
moving parts. Replace damaged
Power Cords immediately.
Damaged Power Cords increase the
risk of electric shock.
6. When operating a power tool
outside, sue an outdoor extension
cord marker “W-A” or “W”. These
extension cords are rated for outdoor
use, and reduce the risk of electric
shock.
Personal Safety
1. Stay alert. Watch what you are
doing, and use common sense
when operating a power tool. Do
not use a power tool while tired or
under the influence of drugs,
alcohol, or medication. A moment of
inattention while operating power tools
may result in serious personal injury.
2. Dress properly. Do not wear loose
clothing or jewelry. Contain long
hair. Keep your hair, clothing, and
gloves away from moving parts.
Loose clothes, jewelry, or long hair
can be caught in moving parts.
3. Avoid accidental staring. Be sure
the Power Switch is off before
plugging in. Carrying power tools
with your finger on the Power Switch,
or plugging in power tools with the
Power Switch on, invites accidents.
4. Remove adjusting keys or
wrenches before turning the power
tool on. A wrench or a key that is left
attached to a rotating part of the power
tool may result in personal injury.
5. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables
better control of the power tool in
unexpected situations.
6. Use safety equipment. Always wear
eye protection. Dust mask, non-skid
safety shoes, hard hat, or hearing

protection must be used for
appropriate conditions.
Tool Use and Care
1. Use clamps (not included) or other
practical ways to secure and
support the workpiece to a stable
platform. Holding the work piece by
hand to against your body is unstable
and may lead to loss of control.
2. Do not force the tool. Use the
correct tool for your application.
The correct tool will do the job better
and safer at the rate for which it is
designed.
3. Do not use the power tool if the
Power Switch does not turn it on or
off. Any tool that cannot be controlled
with the Power Switch is dangerous
and must be replaced.
4. Disconnect the Power Cord Plug
from the power source before
making any adjustments, changing
accessories, or storing the tool.
Such preventive safety measures
reduce the risk of starting the tool
accidentally.
5. Store idle tools out of reach of
children and other untrained
persons. Tools are dangerous in the
hands of untrained users.
6. Maintain tools with care. Keep
cutting tools maintained and clean.
Properly maintained tools are less
likely to bind and are easier to control.
Do not use a damaged tool. Tag
damaged tools “Do not use” until
repaired
7. Check for misalignment or binding
of moving parts, breakage of parts,
and any other condition that may
affect the tool’s operation. If
damaged, have the tool serviced
before using. Many accidents are
caused by poorly maintained tools.
8. Use only accessories that are
recommended by the manufacturer
for your model. Accessories that may
be suitable for one tool may become
hazardous when used on another tool.
Service
1. Tool service must be performed only
by qualified repair personnel. Service
or maintenance performed by
unqualified personnel could result in a
risk of injury.
2. When servicing a tool, use only
identical replacement parts. Use of
unauthorized parts or failure to follow
maintenance instructions may create a
risk of electric shock or injury.

Tungsten Inert Gas (TIG) Welding
Gas tungsten arc welding (GTAW),
also known as tungsten inert gas (TIG)
welding, is an arc welding process that
uses a no consumable tungsten electrode
to produce the weld. The weld area is
protected from atmospheric contamination
by a shielding gas (usually an inert gas
such as argon), and a filler metal is
normally used, though some welds, known
as autogenously welds, do not require it. A
constant-current welding power supply
produces energy which is conducted
across the arc through a column of highly
ionized gas and metal vapors known as
plasma. TAW is most commonly used to
weld thin sections of stainless steel and
non-ferrous metals such as aluminum,
magnesium, and copper alloys. The
process grants the operator greater
control over the weld than competing
procedures such as shielded metal arc
welding and gas metal arc welding,
allowing for stronger, higher quality welds.
However, GTAW is comparatively more
complex and difficult to master, and
furthermore, it is significantly slower than
most other welding techniques. A related
process, plasma arc welding, uses a
slightly different welding torch to create a
more focused welding arc and as a result
is often automated.
