These connections instructions apply to both the LN-25 Pro and
Activ8 models. These feeders have 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.
• Attach the single lead from the front of the feeder 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 weld-
ing current (See Figure A.8).
• Set the MODE switch to the "CV-WIRE" position (See Figure A.7).
• Set the "WELD TERMINALS" switch to "WELD TERMINALS ON"
• Set the "ARC CONTROL" knob to "0" initially and adjust to suit.
• Set the “REMOTE/LOCAL” switch to “LOCAL” control.
