n-
structed using the finest components and material available.
Used properly, this equipment will give you many years of
profitabl
e, efficient service.
The system incorporates the latest in engineering advances
for complete, reliable end welding of mild ste

3.0 UNPACKING YOUR UNIT
Upon receipt of your unit, place it as close as possible to the
point of installation before unpacking it. Once the unit is u
n-
packed, it is recommended that you inspect it for any phys
i-
cal damage that may have occurred in shipping.
Y
our unit has been completely assembled and inspected at
the factory. Upon receipt, the unit must be hooked up to the
recommended
incoming power before welding.
Place the unit in a large enough area to provide adequate
ve
n
tilation. Do not restrict the air flow around the front lou-
vers or from the fan at the rear of the unit. Do not allow w
a-
ter to enter the unit in any way.
4.0 SUGGESTED SAFETY PRECAUTIONS
In any welding operation, it is the responsibility of the
welder
to observe all safety rules to insure his or her personal safety
and to protect those working in the area.

4.1 Personal Safety Precautions
1. Always treat electricity with respect. Under open circuit
conditions, the welding machines output voltage may be da
n-
gerous.
2. Don’t work on live circuits or conductors. Disconnect the
main power before checking the machine or performing any
maintenance or repair operations.
3. Be sure the welding machine cabinet is properly grounded
to a good electrical ground. Con
sult local electrical codes.
4. Never operate a welder in the rain, or operate a welder
while standing in water. Avoid wearing
wet or sweaty clothes
when welding.
5. Don’t operate with worn or poorly connected cables, and
don’t operate the weld gun with loose cable connections. I
n-
spect all cables frequently for insulation failures, exposed
wires, loose connections and repair as needed.
6. Don’t overload w
elding cables or continue to operate with
over heated cables.
7. Don’t weld near flammable materials or liquids in or near
the
area, or on ducts or pipes carrying explosive gases.
8. Don’t weld on containers which have held combustible or
flammable materials, or on materials which give off flamm
a-
ble or toxic vapors when heated.
