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 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.
Always be sure
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.

coatings and cleaners.
LOCATION
Selecting the proper location can
significantly increase performance,
reliability and life of the arc welder.
●
For best results locate the
welder/generator in an
environment that is clean and dry.
Dust and dirt in the unit retain
moisture and increase wear of
moving parts.
●
Store electrodes in a clean, dry
location with low humidity to
preserve the flux coating.
PRE-OPERATION
1. Check engine oil level. Oil is NOT
mixed with the gasoline, however
adequate oil supply is necessary for
proper engine lubrication. Refer to
the Engine Manual for SAE, API and
fill quantity specifications. Unit is
shipped without oil in engine.
2. Use of a Ground Fault Interrupter
(GFI) is strongly recommended.
Ground Fault Interrupters can
significantly reduce the possibility of
injury if an electrical short occurs. In
order to install a GFI, the
welder/generator neutral wire must
be internally grounded to the
welder/generator frame, and the
frame must be properly grounded
to the earth.
A Ground Fault
Interrupter may
not be effective if used on a
welder/generator that is not grounded!
Refer to the section entitled Grounding
for proper steps to ground the
welder/generator.
!
WARNING
3. When installing a GFI, be sure to
follow all national and local
regulations. If not sure of
regulations or procedures, obtain
assistance from a qualified (licensed
or certified) electrical technician.
GROUNDING
1. Use the ground terminal and wing
nut on the welder/generator frame
to connect the unit to a suitable
ground source. Securely fasten the
end terminal of the ground wire to
the ground terminal on the
welder/generator frame. Tighten
the washer and wing nut on top of
the ground wire end terminal.
2. The ground wire should be made of
#8 gauge wire. Do not use wire with
a higher gauge number. Higher
gauge numbers indicate thinner
wire, which may not provide an
adequate ground path.
3. The other end of the ground wire
must be securely fastened to an
approved ground source.
The following are ground sources
approved by the National Electric Code.
Other ground sources may be
acceptable. Refer to the National Electric
Code and local regulations for further
ground source information. If not sure
of regulations or procedures, obtain
assistance from a qualified (licensed or
certified) electrical technician.
a. An underground water pipe at
least ten feet in length
b. A non-corrosive underground
pipe at least eight feet in length
and 3/4 inch diameter
c. A steel or iron underground rod
at least eight feet in length and
5/8 inch diameter
d. A non-ferrous rod at least eight
feet in length, 1/2 inch in
diameter, and approved for
grounding purposes
Any rod or pipe used for grounding must
be driven to eight feet deep or buried in
the deepest possible trench.
STARTING
1. Remove all electrical loads from the
welder/generator.
