PRODUCT DESCRIPTION
The SAM engine welders are multi-purpose welding
machines. They are designed to be used on all open
arc or submerged arc processes within the rating of the
unit.
The machine is designed to be used with the following
automatic equipment: LN-7, LN-8, LN-9, LN-22, LN-
23P (with Adapter Kit), LN-25, NA-3, LT-7, or LT-56. It
can be used with most other equipment whose power
requirements do not exceed the rating of the machine.
The SAM machines have two types of output charac-
teristics; a variable voltage output characteristic for
stick and submerged arc welding and also constant
voltage characteristics for Innershield® plus both dip-
transfer and spray-transfer processes.
INSTALLATION PRECAUTIONS
SPARK ARRESTER
Some federal, state or local laws may require that
diesel engines be equipped with exhaust spark
arresters when they are operated in certain locations
where unarrested sparks may present a fire hazard.
The standard mufflers included with these welders do
not qualify as spark arresters. When required by local
regulations suitable spark arresters must be installed
and properly maintained.
An incorrect arrester may lead to damage of the
engine or its performance. Contact the engine
manufacturer for specific recommendations.
MACHINE GROUNDING
The 1984 National Electrical Code does not require
this machine to be grounded under normal operating
circumstances.
Some state, local or other codes or unusual operating
circumstances may require the machine frame to be
grounded. It is recommended that you determine the
extent to which such requirements may apply to your
particular situation and follow them explicitly. A
machine grounding stud marked with the symbol
is
provided on the welding generator frame foot.
In general, if the machine is to be grounded it should
be connected with a #8 or larger copper wire to a solid
earth ground such as a metal water pipe going into the
ground for at least ten feet and having no insulated
joints, or to the metal framework of a building which
has been effectively grounded. The National Electrical
Code lists a number of alternate means of grounding
electrical equipment.
ADDITIONAL SAFETY PRECAUTIONS
FALLING EQUIPMENT can cause
injury.
● Do not lift this machine using lift
bale if it is equipped with a heavy
accessory such as trailer or gas
cylinder.
● Lift only with equipment of adequate lifting
capacity.
● Be sure machine is stable when lifting.
The recommended undercarriage for use with this
equipment for in-plant and yard towing by a vehicle is
Lincoln’s K767-1. If the user adapts a non-Lincoln
undercarriage, he must assume responsibility that the
method of attachment and usage does not result in a
safety hazard nor damage the welding equipment.
Some of the factors to be considered are as follows:
1. Design capacity of undercarriage vs. weight of
Lincoln equipment and likely additional attach-
ments.
2. Proper support of, and attachment to, the base of
the welding equipment so there will be no undue
stress to the framework.
3. Proper placement of the equipment on the under-
carriage to insure stability side to side and front to
back when being moved and when standing by itself
while being operated or serviced.
4. Typical conditions of use, i.e., travel speed; rough-
ness of surface on which the undercarriage will be
operated; environmental conditions; likely mainte-
nance.
5. Conformance with federal, state and local laws. (1)

specific requirements for use on public highways.
