General Safety
Take precautions to be sure that
flying sparks and heat do not cause
flames in hidden areas, cracks,
behind bulkheads, etc.
Fire hazard! Do not
weld on containers or
pipes that contain or
have contained
flammable materials or
gaseous or liquid combustibles.
Arc welding closed
cylinders or containers
such as tanks or drums
can cause 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.
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.
Keep the head and face out of the
welding fumes.
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.
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
(Con't)
prior to performing any electric arc
welding operations.
Route the electrode and work
cables together and secure with
tape when possible.
Never wrap arc welder cables
around the body.
Always position the electrode and
work leads so that they are on the
same side of the body.
Exposure to electromagnetic fields
during welding may have other
health effects which are not known.
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.

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.
Store electrodes in a clean, dry
location with low humidity to
preserve the flux coating.
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 Amps chart on page 1 for
correct circuit capacity.
The use of an extension cord is not
recommended for arc welding
machines. Extension cord use will
significantly degrade the
performance of the welder.
