General Safety
(Continued)
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.
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.
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.
Route the wire gun and work cables
together and secure with tape
when possible.
Never wrap arc welder cables
around the body.
Always position the wire gun 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.
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 excess
wire is cut off. Be sure that cables are
loosely coiled and out of the way. Be
sure that all metal and slag has cooled.
DANGER
!
Cylinders can explode if
damaged. Shielding gas
cylinders contain gas under high
pressure. If damaged, a cylinder can
explode. Since gas cylinders are
normally part of the welding process,
be sure to treat them carefully.
Protect compressed gas cylinders
from excessive heat, mechanical
shocks, and arcs.
Install and secure cylinders in an
upright position by chaining them
to stationary support or equipment
cylinder rack to prevent falling or
tipping.
Keep cylinders away from any
welding or other electrical circuits.
Never allow a welding electrode to
touch any cylinder.
Use only correct shielding gas
cylinders, regulators, hoses, and
fittings designed for the specific
application; maintain them and
associated parts in good condition.
Turn face away from valve outlet
when opening cylinder valve.
Keep protective cap in place over
valve except when cylinder is in use
or connected for use.
Read and follow instructions on
compressed gas cylinders, associated
equipment, and CGA publication P-1
listed in Safety Standards.
Never use
DANGER
!
flammable gasses
with MIG welders. Only inert or non-
flammable gasses such as carbon
dioxide, argon, helium, or mixtures of
one or more of these gasses are
suitable for MIG welding.
Never lift cylinders
WARNING
!
off the ground by
their valves, caps, or with chains or slings.

and cleaners.
Installation
Selecting the proper location can
significantly increase performance,
reliability and life of the arc welder.
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.
Place the welder in an area that
provides at least 12" (30,48 cm) of
ventilation space at both the front
and rear of the unit. Keep all
obstructions away from this
ventilation space.
Store wire in a clean, dry location
with low humidity to preserve the
wire 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 electric arc
welding machines. The voltage drop
in the extension cord may signifi-
cantly degrade the performance of
the welder.
