General Safety
(Continued)
explosion if not properly vented!
Verify that any cylinder or container to
be welded has an adequate ventilation
hole, so that expanding gases can be
released.
WARNING
!
Do not breathe fumes that
are produced by the arc
welding operation. These
fumes are dangerous. If the welding
area cannot be adequately ventilated,
be sure to use an air-supplied
respirator.
G Keep the head and face out of the
welding fumes.
G Do not perform electric arc welding
operations on metals that are
galvanized or cadmium plated, or
contain zinc, mercury, or beryllium
without completing the following
precautions:
a. Remove the coating from the
base metal.
b. Make sure that the welding area
is well-ventilated.
c. Use an air-supplied respirator.
Extremely toxic fumes are created
when these metals are heated.
WARNING
!
The electromagnetic field
that is generated during arc
welding may interfere with
the operation of various electrical and
electronic devices such as cardiac
pacemakers. Persons using such devices
should consult with their physician
prior to performing any electric arc
welding operations.
G Route the electrode and work
cables together and secure with
tape when possible.
G Never wrap arc welder cables
around the body.
G Always position the electrode and
work leads so that they are on the
same side of the body.
G Exposure to electromagnetic fields
during welding may have other
health effects which are not known.
Always be sure
WARNING
!
that the welding
area is secure and free of hazards
(sparks, flames, glowing metal or slag)
prior to leaving. Be sure that
equipment is turned off and electrode
is removed. Be sure that cables are
loosely coiled and out of the way. Be
sure that all metal and slag has cooled.

Installation
Location
Selecting the proper location can
significantly increase performance,
reliability and life of the arc welder.
G For best results locate the welder in
an environment that is clean and
dry. Dust and dirt in the welder
retain moisture and increase wear
of moving parts.
G Store electrodes in a clean, dry
location with low humidity to
preserve the flux coating.
G The receptacle used for the welder
must be properly grounded and the
welder must be the only load on the
power supply circuit. Refer to the
Circuit Amperage chart on page 1
for correct circuit capacity.
G The use of an extension cord is not
recommended for arc welding
machines. Extension cord use will
significantly degrade the
performance of the welder.
Assembly
HANDSHIELD
1. Cut detachable handle away from
shield. Trim the excess plastic to
remove sharp edges.

3. To attach the handle, place shield on
a flat surface and press handle into
place (See Figure 5).

NOTE: If you have never welded before
or have little experience, a full face
helmet is recommended. Both hands
are needed to stabilize and control the
angle and arc length of the electrode.
