ELECTRODE CONNECTION

Route the electrode cable through the strain relief in
the rear of the case. Connect the electrode cable to
the LN-15 connection block using the mounting hard-
ware provided. Secure the cable by tightening the
strain relief.
All domestic models are supplied with an optional pig-
tail for customers that prefer to make a taped and bolt-
ed connection externally. CE models have a male
twist connector for the electrode connection.

WORK CONNECTION

Connect a work lead of sufficient size between the
proper output stud on the power source and the work.
Be sure the connection to the work makes tight metal
to metal electrical contact. Poor work lead connec-
tions can result in poor welding performance.

POWER SOURCE CONNECTION

The LN-15 can be used with any DC welding power
source. A constant voltage power source is recom-
mend; however, the LN-15 can also be used with a
constant current power source as long as the open
circuit voltage is less than 110VDC.
CAUTION
To prevent possible damage to the LN-15, do not
connect the LN-15 to non-Lincoln TIG or square
wave power sources. TIG high frequency should
never be applied to the LN-15.

ENGINE DRIVE POWER SOURCE
CONNECTION
The LN-15 sends a control signal to the engine drive
and the electrode is not energized until the gun trigger
is closed. When the gun trigger is closed the wire will
begin to feed and the welding process is started.
1. Shut the welder off.
2. For electrode Positive polarity welding, connect the
electrode cable to the "+" terminal of the welder
and work cable to the "-" terminal of the welder. For
Electrode Negative welding, connect the electrode
cable to the "-" terminal of the welder and work
cable to the "+" terminal of the welder.
3. Set the MODE switch on the engine drive to CV-
WIRE.
