CONNECTION OF LN-15 TO THE AIR VANTAGE®

These connections instructions apply to both the LN-15 Across-
The-Arc and Control Cable models. The LN-15 has an internal
contactor 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.
• Shut the welder off.
• For electrode Positive, connect the electrode cable to the "+"
terminal of the welder and work cable to the "-" terminal of the
welder. For electrode Negative, connect the electrode cable "-"
terminal of the welder and work cable to the "+" terminal of the
welder.
• Across The-Arc Model:
Attach the single lead from the front of the LN-15 to work
using the spring clip at the end of the lead. This is a control
lead to supply current to the wire feeder motor; it does not
carry welding current.
Control Cable Model:
Connect Control Cable between Engine Welder and Feeder.
• Set the MODE switch to the "CV-WIRE " position.
• Across The-Arc Model:
